N2 + 3 H2 --> 2 NH3
The balanced equation above indicates that if 2 moles of N2 react, then

2 moles of H2 will also react
3 moles of H2 will also react
4 moles of NH3 will be produced
2 moles of NH3 will be produced

Answers

Answer 1

Answer:

4 moles of NH3 will be produced

Explanation:

The reaction expression is given as:

            N₂  +  3H₂  →  2NH₃

We have to check that the equation of the reaction is balanced.

 Then;

      if 2 mole of N₂ reacts;

 1 mole of N₂ will react with 3 mole of H₂ to produce 2 mole of NH₃

2 mole of N₂ will react with (2x3)mole of H₂ to produce (2x2)mole of NH₃

                                                    6mole of H₂ to produce      4 mole of NH₃

Answer 2

Answer:

According to the balanced chemical equation N2 + 3 H2 --> 2 NH3, for every 1 mole of N2 that reacts, 3 moles of H2 are required to react completely to form 2 moles of NH3. Therefore, if 2 moles of N2 react, then 6 moles of H2 will also react to form 4 moles of NH3.

So the correct answer is: 6 moles of H2 will also react, and 4 moles of NH3 will be produced.

A 10.3 L cylinder contains 10.67 moles of Cl2 at 21.2 C. What is the pressure (atm)

Answers

Answer:

Explanation:

we know that ideal gas equation is

PV=nRT

P=nRT/V

V=10.3L

n=10.67

T=21.2+273=294

R=0.0821

P=10.67*0.0821*294/10.3

P=25.00atm

Answer:

P = 25.0 atm

Explanation:

Given data:

Volume of gas = 10.3 L

Number of moles of Cl₂ = 10.67 mol

Temperature = 21.2 °C

Pressure of gas = ?

Solution:

The given problem will be solve by using general gas equation,

PV = nRT

P= Pressure

V = volume

n = number of moles

R = general gas constant = 0.0821 atm.L/ mol.K  

T = temperature in kelvin

Now we will convert the temperature.

21.2+273 = 294.2 K

10.3 L × P = 10.67 mol ×  0.0821 atm.L/ mol.K  × 294.2 K

P = 257.72 atm.L /  10.3 L

P = 25.0 atm

I got it right if you got it right leave a like

Explanation:

The chemical equilibrium is given:

2NO (g) + O2(g) <—>2N O2, (g)

In a container of volume 10L is in equilibrium a mixture consisting of 10 mol NO (g), 10 mol O2, (g) and 20 mol NO2, (g).

The volume of the container changes under constant temperature and after the restoration of equilibrium the amount of NO has increased by 25%. Calculate the volume change in L.

How do I find the change in volume?

P.s sorry if my English isn’t perfect.

Answers

The volume of NO₂=6.25 L

Further explanation

Avogadro's stated :

In the same T,P and V, the gas contains the same number of molecules  

So the ratio of gas volume = the ratio of gas moles  

[tex]\tt \dfrac{V_1}{V_2}=\dfrac{n_1}{n_2}[/tex]

the volume of each gas (in a container of volume 10L) :

Total mol=10+10+20=40 mol

NO :

[tex]\tt \dfrac{10}{40}\times 10=2.5~L[/tex]

O₂ :

[tex]\tt \dfrac{10}{40}\times 10=2.5~L[/tex]

NO₂ :

[tex]\tt \dfrac{20}{40}\times 10=5~L[/tex]

NO₂ (has increased by 25%) :

[tex]\tt 0.25\times 5~L=1.25\\\\new~volume=5+1.25=6.25[/tex]

O₂ :

2.911 grams of ethanol C2H5OH is burned and produces how many grams of water vapor?
Please help me or I'm dead.

Answers

Answer:

3.4g

Explanation:

Given parameters:

Mass of ethanol  = 2.911g

Unknown:

Mass of water vapor = ?

Solution:

To solve this problem, let us write the balanced reaction equation first;

             C₂H₅OH  + 3O₂  → 2CO₂  + 3H₂O

Now find the number of moles of ethanol;

  Number of moles  = [tex]\frac{mass}{molar mass}[/tex]

    Molar mass of ethanol = 2(12) + 5(1) + 16 + 1 = 46g/mol

  Number of moles  = [tex]\frac{2.911}{46}[/tex]   = 0.06mole

  So;

       1 mole of ethanol will produce 3 moles of water vapor

      0.06mole of ethanol will produce 0.06 x 3  = 0.19moles of water vapor

 Mass of water vapor  = number of moles x molar mass

   Molar mass of H₂O  = 2(1) + 16  = 18g/mol

  Mass of water vapor  = 0.19 x 18  = 3.4g

3. A student measured 15.0 grams of ice in a beaker. The beaker was then
placed on a hot plate where it was heated uniformly for a certain amount
of time. During the melting process of the ice, the student noted that the
temperature was at O degree Celsius. When all the ice converted to water,
the final temperature was also at 0 degree Celsius. How much heat was
used to melt the ice?
Please help me !

Answers

Answer:

The heat that was used to melt the 15.0 grams of ice at 0°C is 4,950 Joules

Explanation:

The mass of ice in the beaker = 15.0 grams

The initial temperature of the ice = 0°C

The final temperature of the ice = 0°C

The latent heat of fusion of ice = 330 J/g

The heat required to melt a given mass of ice = The mass of the ice to be melted × The latent heat of fusion of ice

Therefore, the heat, Q, required to melt 15.0 g of ice = 15.0 g × 330 J/g = 4,950 J

The heat that was used to melt the 15.0 grams of ice = 4,950 Joules.

2. removing N2 causes the equilibrium to shift left - produce more reactants

3.  same as number 2

4. decreasing pressure causes equilbrium to shift to the side with more moles so it shifts left and produces more reactants

5. catalyst doesn't change anything about equlibrium, it only affects the reaction's rate

Hey There!_____________________________________Answer:LE CHATELIER PRINCIPLE:

Le Chatelier's principle is a principle which predicts the effect of change in condition on a the position of a equilibrium.  

Change could be in Temperature, Moles(Concentration), Pressure.

-------------------------------------------------------------------------------------------------------------

EFFECTS ON EQUILIBRIUM__________________________________________________Temperature:

We could change the temperature by increasing or decreasing it, and there are two types of reactions, endothermic or exothermic, both have different outcomes by changing the condition.

__________________________________________________________

In Endothermic,

When we increase the temperature, It will favor the formation of product thus MORE PRODUCT will be formed - equilibrium will shift towards right i.e. product side.

When we decrease the temperature, It will favor the formation of reactants thus MORE reactant will be formed - equilibrium will shift towards left i.e. reactants side.

__________________________________________________________

In Exothermic,

When we increase the temperature, It will favor the formation of reactants thus MORE REACTANT will be formed - equilibrium will shift towards left i.e. reactants side.

When we decrease the temperature, It will favor the formation of product thus MORE PRODUCT will be formed - equilibrium will shift towards the right i.e. product side

_____________________________________Pressure:

When we increase the pressure, The equilibrium shifts towards the fewer moles of a gas. Wherever there are less moles, it could be any, reactant or product, the increase of Pressure will favor in formation of them.

When we decrease the pressure, The equilibrium shifts towards the more moles of a gas. So whether reactants or product have the higher moles, the decrease in pressure will favor in the formation of them.

_____________________________________Concentration of moles:

When we increase the concentration of moles of any substance, The equilibrium will shift away from that substance. So if we want to make more product and there are more moles of reactant present, then Increase the concentration of reactants.

When we decrease the concentration of any substance, The equilibrium will shift towards that substance. So if we want to make more product, decrease its concentration or add more reactant.

_____________________________________Catalyst:

By the use of the catalyst, There is no effect on the equilibrium. The rate of  both forward and backward reaction are increased with the equal amount.

_____________________________________Question:

By keeping that in mind,

A) Extra [tex]NH_{3}[/tex] will shift the equilibrium towards left i.e. more reactants will be formed.

B) Extra N2 is removed, the equilibrium will shift towards the left i.e. more reactants will be formed.

C) N2 is added, the equilibrium will shift towards right i.e. more PRODUCT will be formed. (I assumed there was a typing error and it meant Addition instead of removal)

D) When we decrease the pressure the equilibrium will shift towards the left i.e. more reactant will be formed.

E) Catalyst has no effect on the system

Electrons are defined as a subatomic particle with a negative charge that makes up the nucleus of an atom along with protons and neutrons. Electrons are fundamental to many physical processes, including gravity, electromagnetic interactions, weak interactions, electricity, magnetism, chemistry, and thermal conductivity.

Noble gases are defined as any of a class of extremely stable, very slow-reacting rare gases, such as helium, neon, argon, krypton, xenon, and typically radon. In order of mass, the noble gases are helium, argon, krypton, xenon, and radon. They are known as noble gases because of how beautiful they are and how little they generally react with anything. For this reason, they are also referred to as inert gases. The outer shell of the noble gas are completely filled.

Non-ionizing radiation has enough energy to move atoms in a molecule around or cause them to vibrate, but not enough to remove electrons from atoms. Examples of this kind of radiation are radio waves, visible light and microwaves.

Ionizing radiation has so much energy it can knock electrons out of atoms, a process known as ionization. Ionizing radiation can affect the atoms in living things, so it poses a health risk by damaging tissue and DNA in genes. Ionizing radiation comes from x-ray machines, cosmic particles from outer space and radioactive elements. Radioactive elements emit ionizing radiation as their atoms undergo radioactive decay.

How do the wire and cover compare in their ability to conduct or insulate electricity? A. The wire is a conductor, and the cover is an insulator. B. The wire is an insulator, and the cover is a conductor. C. Both the wire and the cover are insulators. D. Both the wire and the cover are conductors.

Answers

Answer:

A

Explanation:

The correct answer would be that the wire is a conductor and the cover is an insulator.

The wire inside an electrical cord is made up of metals and metals are generally considered to be good conductors of heat and electricity. The cover which is made of plastic or rubber, however, are known to be poor conductor of electricity. Hence, the wire are considered to be conductors of electricity while the rubber covers act as insulators to protect users from getting electrocuted.
