"Fog forms in a valley", a physical process called condensation occurs when a gas or vapour transforms into a liquid state.

On a chilly soda can, water gathers. As the air cools around the container, water vapor in the atmosphere reaches its dew point and condenses into liquid droplets. Condensation is the conversion of water vapor into liquid. On the outside of a chilly glass or container, water vapor condenses and turns into liquid water (sweat).

Aldol condensation, Knoevenagel condensation, Claisen condensation, and Dieckman condensation (intramolecular Claisen condensation) are a few examples of common condensations that produce alcohols as a by-product.

Explanation:

Hello there!

In this case, by knowing that the kinetic energy is such energy associated to the movement of an object, it is possible for us to recall the formula for its calculation in terms of mass and velocity as shown below:

[tex]K=\frac{1}{2} mv^2[/tex]

Thus, given the mass and velocity, it is possible to obtain the following kinetic energy:

[tex]K=\frac{1}{2} (5kg)(10m/s)^2\\\\K=250J[/tex]

557.3J is the work of expansion of the CO2 gas

Explanation:

The work of expansion of a gas under constant temperature and pressure (Isobaric pressure) is:

W = P*ΔV

Where W is work

P is pressure = 1.0atm

ΔV = Final volume - Initial Volume = 6.5L - 1.0L = 5.5L

Replacing:

W = 1.0atm*5.5L

W = 5.5atmL

Answer:

The molarity will be "0.26 M".

Explanation:

The given values are:

Mass,

= 2.00 g

Volume of solution,

= 100 mL

or,

= [tex]\frac{100}{1000}[/tex]

= [tex]0.1 \ L[/tex]

Molar mass of KCl,

= 74.5 gm

Now,

Moles of KCl will be:

=  [tex]\frac{Given \ mass}{Molar \ mass}[/tex]

=  [tex]\frac{2}{74.5}[/tex]

=  [tex]0.026[/tex]

hence,

The molarity will be:

=  [tex]\frac{Moles \ of \ solute}{Volume \ of \ solution}[/tex]

On substituting the values, we get

=  [tex]\frac{0.026}{0.1}[/tex]

=  [tex]0.26 \ M[/tex]

Answer:

2HBr + Ba(OH)2 → BaBr2 + 2H2O

Explanation:

Hydrogen Bromide + Barium Hydroxide = Barium Bromide + Water

The balanced chemical equation with the correct coefficients is 2HBr + Ba(OH)₂ → BaBr₂ + 2H₂O.

First balancing the barium (Ba) atoms first. There is one barium atom on the left side and one on the right side, so no coefficients are needed for barium.

HBr + Ba(OH)₂ → BaBr₂ + H₂O

There is one hydrogen atom on the left side and two hydrogen atoms on the right side. To balance the hydrogen, place a coefficient of 2 in front of HBr:

2HBr + Ba(OH)₂ → BaBr₂ + H₂O

There are two bromine atoms on the left side and two bromine atoms on the right side, so they are already balanced.

2HBr + Ba(OH)₂ → BaBr₂ + H₂O

There is one barium atom on the left side and one barium atom on the right side, so they are already balanced.

Balance the oxygen (O) atoms. There are two oxygen atoms on the left side and only one on the right side. To balance the oxygen, place a coefficient of 2 in front of H₂O.

2HBr + Ba(OH)₂ → BaBr₂ + 2H₂O

Answer:

The limiting reactant is CuSO₄.

Explanation:

The reaction is:

Fe(s) + CuSO₄(aq) → FeSO₄(aq) + Cu(s)      (1)

To find the limiting reactant we need to find the number of moles of the reactants.

[tex] \eta_{Fe} = \frac{m}{A_{r}} [/tex]

Where:

m: is the mass of iron = 3.26 g  

[tex]A_{r}[/tex]: is the standard atomic weight of iron = 55.845 g/mol

[tex]\eta_{Fe} = \frac{3.26 g}{55.845 g/mol} = 0.058 moles [/tex]

[tex] \eta_{CuSO_{4}} = M*V [/tex]                

Where:

M: is the concentration of the CuSO₄ = 0.200 mol/dm⁻³

V: is the volume of the solution = 80.0 cm³

First, we need to convert the units of the volume to dm³ knowing that 1 dm = 10 cm and 1 L= 1 dm³.

[tex] V = 80.0 cm^{3}*\frac{1 dm^{3}}{(10 cm)^{3}} = 0.080 dm^{3} [/tex]

Now, the number of CuSO₄ moles is:

[tex] \eta_{CuSO_{4}} = M*V = 0.200 mol/dm^{3}*0.080 dm^{3} = 0.016 moles [/tex]            

So, to determine the limiting reactant we need to use the molar ratio from equation (1), Fe:CuSO₄ = 1:1

[tex]\eta_{Fe} = \frac{1 mol Fe}{1 mol CuSO_{4}}*0.016 moles \: CuSO_{4} = 0.016 moles[/tex]

Since we need 0.016 moles of Fe to react with 0.016 moles of CuSO₄ and initially we have 0.058 moles of Fe, then the limiting reactant is CuSO₄.  

Therefore, the limiting reactant is CuSO₄.  

I hope it helps you!

The limiting reactant would be CuSO4

Looking at the equation of the reaction:

Fe (s) + CuSO4 (aq) → FeSO4 (aq) + Cu (s)

The mole ratio of Fe to CuSO4 is 1:1. Thus, every 1 mole of Fe will require 1 mole of CuSO4 for reaction.

Recall that: mole = mass/molar mass

Also: mole = molarity x volume

mole of Fe = 3.26/55.8

                    = 0.058 moles

mole of CuSO4 = 0.200 x 80/1000

                            = 0.016

The mole of Fe in the reaction is more than the mole of CuSO4. Thus, CuSO4 is the limiting reactant of the reaction. Fe is in excess.

Answer:

Option b (V1/T1 = V2/T2) is the right alternative or the new volume will be "0.048 L".

Explanation:

The given values are:

Temperature,

T₁ = 25°C

or,

   = 298.15 K

T₂ = 50°C

or,

    = 323.15 K

Volume,

V₁ = 45 mL

or,

    = 0.045 L

V₂ = ?

As we know,

⇒  [tex]\frac{V_1}{T_1} =\frac{V_2}{T_2}[/tex]

Or,

⇒  [tex]V_2=\frac{V_1\times T_2}{T_1}[/tex]

On substituting the values, we get

⇒       [tex]=\frac{0.045\times 323.15}{298.15}[/tex]

⇒       [tex]=\frac{14.541}{298.15}[/tex]

⇒       [tex]=0.048 \ L[/tex]

Answer:

Oxidation - reduction reaction which is called redox reaction.

Explanation:

The type of reaction that is a part of another type but treated separately is called Oxidation - reduction reaction.

Thus is because they usually involve 2 separate half reactions which are oxidation reactions that involve loss of electrons and then reduction equations which involve gain of electrons.

They are treated separately for example when sodium reacts with chlorine to form sodium chloride.

2Na + Cl2 = 2NaCl

Now, sodium undergoes oxidation by loosing elctrons and it's half reaction is;

2Na → 2Na​^(+) + 2e^(-)

​​Meanwhile chlorine undergoes reduction by gaining electrons and its half reaction is;

Cl2 + 2e^(-) → 2Cl^(-)

[Cl-18]⁻ & [Cl-20]⁻

Explanation:

By definition isotopes are elements with the same number of protons by different number of neutrons. Elements X-18 & X-20 have 17 protons and represent Chlorine isotopes Cl-18 & Cl-20 each with 17 protons and 18 electrons to give the isotopes a -1 oxidation state. Both isotope of chlorine have 7 electron in its valence shell and 10 electrons in its core structure.  Gaining 1 electron fills the valence octet and establishes a -1 oxidation state.
