The final volume of the gas that was heated from -25.0 °C to standard temperature is 2.2L.

<h3>How to calculate volume?</h3>

The volume of a given gas can be calculated using the Charles law equation as follows:

V1/T1 = V2/T2

Where;

V1 = initial volume
V2 = final volume
T1 = initial temperature
T2 = final temperature

V1 = 2L
V2 = ?
T1 = -25°C + 273 = 248K
T2 = 273K

2/248 = V2/273

273 × 2 = 248V2

546 = 248V2

V2 = 546/248

V2 = 2.2L

Therefore, the final volume of the gas that was heated from -25.0 °C to standard temperature is 2.2L

Each of the following reactions is allowed to reach equilibrium in a sealed container. For which of the reactions could you shif

natta225 [31]

Answer:

None of the reaction will be favored to the right by a decrease in pressure.

Explanation:

CH₄(g) + 2O₂(g) ⇄ CO₂(g) + 2H₂O(l)

CaCO₃(s) ⇄ CaO(s) + CO₂(g)

Br₂(g) + 3Cl₂(g) ⇄ 2BrCl₃(g)

2H₂S(g) + 3O₂(g) ⇄ 2SO₂(g) + 2H₂O(g)

From Le Chatellier's principle, we must understand that pressure changes only affects reactions in gaseous phases. The second reaction will not be affected by pressure.

We are now left with three equations.

Also, increase in pressure favors sides with lower volume. We can know the volume from the coefficients in the equation. Now let us check the volumes:

CH₄(g) + 2O₂(g) ⇄ CO₂(g) + 2H₂O(l)

3 moles of gases 3 moles of gases

Br₂(g) + 3Cl₂(g) ⇄ 2BrCl₃(g)

4 moles of gases 2 moles of gases

2H₂S(g) + 3O₂(g) ⇄ 2SO₂(g) + 2H₂O(g)

5 moles of gases 4 moles of gases

None of the reaction will be favored to the right by a decrease in pressure.

The first reaction will not be affected by any change in pressure because the total number of moles on the two sides are equal.

The last two reactions will be favored to the right by increasing pressure and a decrease in pressure will favor the backward left reaction.

Calculate the solubility of carbon dioxide in water at an atmospheric pressure of 0.400 atm (a typical value at high altitude).

likoan [24]

Answer:

1.40*10⁻² M

Explanation:

We have the solubility formula

Solubility,

S = KH*P

where

KH = measure of hardness of water / carbonate hardness = 3.50*10⁻² mol/L.atm

P = atmospheric pressure = 0.400 atm

Hence, we have

S = KH*P

= (3.50*10⁻² mol/L.atm)*(0.400 atm)

= 1.40*10⁻² mol/L

But 1 mol/L = 1 M,

Hence, the answer (1.40*10⁻² mol/L ) is equivalent to

= 1.40*10⁻² M

Balance the chemical equation.Au plus HC l plus HNO 3 right arrow AuC l Subscript 3 Baseline plus NO plus Upper H 2 Upper OAu+HC

tino4ka555 [31]

Answer:

$Au+ 3HCl + HNO_3 \to AuCl_3+NO+2H_2O$

Explanation:

Chemical Equations are representations of chemical reactions in terms of the symbols and formulae of the elements and compounds involved. A chemical equation usually have the reactant at the left hand side while the product is on the right hand side.

A chemical Equation is of little or no value if is not in balanced equation. When an equation is balanced , the total number of atoms of any element on the left-hand side of it must be equal to the total number of atoms of that element on the right hand side.

in the given question; we are given a word problem of chemical symbol to compute and also to balance the chemical equation.

From below; the chemical equation can be written as:

$Au+ HCl + HNO_3 \to AuCl_3+NO+2H_2O$

From the above equation we will notice that it is not truly balanced ; so th balanced equation can be written as:

$Au+ 3HCl + HNO_3 \to AuCl_3+NO+2H_2O$
