if you have 4 moles of n2 and 6 moles of h2, how much would be produced?

Answer:

CO2

Explanation:

Answer: 143*tank temperature/tank pressure L

Explanation: too few data. Need to know the pressure and what if any, temperature change.

tank volume = (tank temp/tank pressure)*(500*200/700) = 143*tank temp/tank pressure L

At constant temperature, (500*700)/tank temp

e.g. at 1400mm Hg, 500*700/1400 = 250L

The main purpose for converting numbers into scientific notation is to make calculations with surpisingly large or small numbers less complicated. Since zeros are not used to place the decimal point, all of the digits in a number in scientific notation are meaningful and easier to read. Hope this helps!

Explanation: google and me.....hope this helps

One factor which scientists used to classify orders of is Soil texture

Soil texture is a classification strategy that scientists used to determine soil classes orders based on their physical texture.

Soil texture and soil structure are unique properties of the soil that will have a great effect on the behavior of soils, such as water holding capacity, nutrient retention and supply, drainage, and nutrient leaching.

Following are the solution to this question:

Explanation:

Evaporate involves pushing to liquid from either a liquid phase. It's used passively, like in the overnight loss of moisture, and aggressively, as in the substrate loss of moisture by the light. The vaporized water is coming from the sea, but only 77% of the precipitation occurs and over the ocean as well as the remaining rain falls over land. Groundwater and rainwater are the primary sources of water.

Answer:

V₂ = 90.42 L

Explanation:

Given data:

Initial volume = 21.4 L

Initial pressure = 681 mmHg (681/760=0.89 atm)

Initial temperature = 42.3 °C (42.3 +273 = 315.3 K)

Final temperature = 221°C (221+273 = 494 K)

Final volume = ?

Final pressure = 248 mmHg(248/760 =0.33 atm)

Formula:

P₁V₁/T₁ = P₂V₂/T₂  

P₁ = Initial pressure

V₁ = Initial volume

T₁ = Initial temperature

P₂ = Final pressure

V₂ = Final volume

T₂ = Final temperature

Solution:

P₁V₁/T₁ = P₂V₂/T₂  

V₂ = P₁V₁T₂/T₁P₂

V₂ = 0.89 atm × 21.4 L × 494 K / 315.3 K × 0.33 atm

V₂ = 9408.72 L /104.05

V₂ = 90.42 L

Answer:

The given substance is cast iron.

Explanation:

Given data:

Mass of substance = 50 g

Heat absorbed = 23000 J

Initial temperature = 250°C

Final temperature = 1250°C

Which metal is this = ?

Solution:

Specific heat capacity:

It is the amount of heat required to raise the temperature of one gram of substance by one degree.

Formula:

Q = m.c. ΔT

Q = amount of heat absorbed or released

m = mass of given substance

c = specific heat capacity of substance

ΔT = change in temperature

ΔT = 1250°C -  250°C

ΔT = 1000°C

23000 j = 50 g ×c ×1000 °C

23000 J = 50,000 g. °C×c

c = 23000 J /50,000 g. °C

c = 0.46 J/g.°C

The given substance is cast iron.

Answer:

a. 2.41 g

Explanation:

First we calculate the number of lithium ion moles (Li⁺) in the solution, multiplying the concentration times the volume:

500 mL ⇒ 500 / 1000 = 0.500 L

Then we convert moles of Li⁺ to moles of Li₃PO₄, keeping in mind that for each mole of Li₃PO₄ there are 3 Li⁺ moles:

Finally we convert Li₃PO₄ moles to grams, using its molar mass:

The mass of lithium phosphate, Li₃PO₄ required to prepare the solution is 2.41 g

The correct answer to the question is Option A. 2.41 g

We'll begin by calculating the concentration of Li₃PO₄. This can be obtained as follow:

Li₃PO₄(aq) —> 3Li⁺(aq) + PO₄³¯(aq)

From the balanced equation above,

3 moles of Li⁺ is present in 1 mole of Li₃PO₄.

Therefore,

0.125 M Li⁺ will be present in = 0.125 / 3 = 0.0417 M Li₃PO₄.

Thus, the concentration of Li₃PO₄ is 0.0417 M

Molarity of Li₃PO₄ = 0.0417 M

Volume = 0.5 L

Mole = Molarity x Volume

Mole of Li₃PO₄ = 0.0417 × 0.5

Mole of Li₃PO₄ = 0.02085 mole

Molar mass of Li₃PO₄ = (3×7) + 31 + (16×4) = 116 g/mol

Mass = mole × molar mass

Mass of Li₃PO₄ = 0.02085 × 116

Thus, the mass of Li₃PO₄ required to prepare the solution is 2.41 g

The correct answer to the question is Option A. 2.41 g

The answer is C or warm objects to cool objects

Explanation:

Heat is the thermal energy flows from one substance to another when the substances differ in temperature. When you drink hot chocolate the heat from the liquid will flow to your mouth.

Answer: H2O and NH3 are polar molecules. H2 is a nonpolar molecule but the H-H bond is also nonpolar.

Therefore, the best choice is CCl4. Although the C-Cl bond is polar due to electronegativity differences, the molecule itself is nonpolar because the net dipole moments cancel out, given its tetrahedral molecular structure.

Answer:

1.209g of MgO participates

Explanation:

In this problem, we have 0.030 moles of MgO that participates in a particular reaction.

And we are asked to solve for the mass of MgO that participates, that means, we need to convert moles to grams.

To convert moles to grams we need to use molar mass of the compound:

1 atom of Mg has a molar mass of 24.3g/mol

1 atom of O has a molar mass of 16g/mol

That means molar mass of MgO is 24.3g/mol + 16g/mol = 40.3g/mol

And mass of 0.030 moles of MgO is:

0.030 moles MgO * (40.3g/mol) =

Explanation:

The rate constant : b. 1/ M² · s

The reaction rate (v) shows the change in the concentration of the substance (changes in addition to concentrations for reaction products or changes in concentration reduction for reactants) per unit time.  

For A + B  ---> C + D

Can be formulated:

[tex]\large{\boxed{\boxed{\bold{v~=~k.[A]^a[B]^b}}}[/tex]

where

v = reaction speed, M / s

k = constant, mol¹⁻⁽ᵃ⁺ᵇ⁾. L⁽ᵃ⁺ᵇ⁾⁻¹. S⁻¹

a = reaction order to A

b = reaction order to B

[A] = [B] = concentration of substances

Units of the rate constant - k depend on rate law, so it is unique for the specific reaction

So for the rate law :

Δ[C]/ΔT = k[A]²[B] , the units are :

[tex]\tt \dfrac{M}{s}=k\times M^2\times M\\\\k=\dfrac{M/s}{M^2\times M}\\\\k=\dfrac{1}{M^2.s}[/tex]

Explanation:

If we look at the structures of each of the compounds we can be able to deduce the accurate hybridization of each of the atoms listed.

Looking at ClNO - we can see that the nitrogen atom is linked to oxygen by a double bond and linked to chlorine by a single bond retaining a lone pair on nitrogen. Hence the nitrogen is in sp2 hybridized state.

For ClOCl, the compound has a sp3 hybridized oxygen atom linked to two chlorine atoms as expected retaining two lone pairs on oxygen.

For NCOH, the carbon atom is doubly bonded to oxygen hence it is sp2 hybridized.

A) Label 2 (Sp2)

B) Label 3 (Sp3)

C) Label 1 (Sp)

Explanation:

A) Have 7 Lone Pairs (LP) to place. 1 on N. 1 becomes a double bond. Double bonds count as 1 Electron Group. Same for single bond and LP. Add these to get 3. 3 coresponds for SP2

B) 8LP. 2LP on O. 2 bonds to O. Add to get 4. 4-> Sp3

Explanation:

Given data:

Number of molecules of F₂ = 3.45 × 10²²

Mass in gram = ?

Solution:

Avogadro number:

The given problem will solve by using Avogadro number.

It is the number of atoms , ions and molecules in one gram atom of element, one gram molecules of compound and one gram ions of a substance.

The number 6.022 × 10²³ is called Avogadro number.

1 mole = 6.022 × 10²³ molecules

3.45 × 10²² molecules ×1 mol / 6.022 × 10²³ molecules

0.57× 10⁻¹  mol

0.057 mol

Mass in gram :

Mass = number of moles × molar mass

Mass = 0.057 mol × 37.9 g/mol

Mass = 2.16 g
