Answer : The volume of gas will be, 113.5 L

Explanation :

Combined gas law is the combination of Boyle's law, Charles's law and Gay-Lussac's law.

The combined gas equation is,

\frac{P_1V_1}{T_1}=\frac{P_2V_2}{T_2}

where,

P_1 = initial pressure of gas = 60 atm

P_2 = final pressure of gas = 30 atm

V_1 = initial volume of gas = 29 L

V_2 = final volume of gas = ?

T_1 = initial temperature of gas = 115 K

T_2 = final temperature of gas = 225 K

Now put all the given values in the above equation, we get:

\frac{60atm\times 29L}{115K}=\frac{30atm\times V_2}{225K}

V_2=113.5L

Therefore, the volume of gas will be, 113.5 L

A scientist measures the standard enthalpy change for the following reaction to be 67.9 kJ:
hodyreva [135]

Answer:

-252.5 kJ/mol = ΔH H2O(g)

Explanation:

ΔH Fe2O3 = -825.5kJ/mol

ΔH H2 = 0kJ/mol

ΔH Fe = 0kJ/mol

Based on Hess's law, ΔH of a reaction is the sum of ΔH of products - ΔH of reactants. For the reaction:

Fe2O3(s) + 3 H2(g) →2Fe(s) + 3 H2O(g)

ΔHr = 67.9kJ/mol = 3*ΔH H2O + 2*ΔHFe - (ΔH Fe2O3 + 3*Δ H2)

67.9kJ/mol = 3*ΔH H2O + 2*0kJ/mol - (ΔH -825.5kJ/mol + 3*Δ H2)

67.9 = 3*ΔH H2O(g) + 825.5kJ/mol

-757.6kJ/mol = 3*ΔH H2O(g)

<h3>-252.5 kJ/mol = ΔH H2O(g)</h3>

How many grams of KNO3, are needed to create 675.0 mL with a concentration of 1.71 M
valkas [14]

Answer:

Бардык белгилүү авиация мыйзамдарына ылайык, аары учуу мүмкүнчүлүгү жок. Канаттары өтө эле кичинекей, семиз денесин чече албайт. Албетте, аары баары бир учат. Себеби аарылар адам мүмкүн эмес деп эсептеген нерсеге маани бербейт.

Given the balanced equation representing a reaction: H2 → H + H What occurs during this reaction? 1. Energy is absorbed as bonds
RoseWind [281]

Answer : The correct option is, (2) Energy is absorbed as bonds are broken.

Explanation :

As we know that the bonds are formed and breaks during the chemical reaction. Some energy is released or absorbed when the bonds are formed and breaks during the chemical reaction.

During the bond breaking, some energy is required to break the bonds.

During the bond formation, some energy is released to the formation of the bonds.

In the given reaction, the bond between the hydrogen-hydrogen in H_2 are breaking into two hydrogen. That means during the bond breaking, some energy is required or absorbed to break the bonds.

Hence, the correct option is, (2) Energy is absorbed as bonds are broken.

The equilibrium constant for the reaction sr(s) + mg2+(aq) ⇌ sr2+(aq) + mg(s) is 3.69 × 1017 at 25°c. calculate e o for a cell m
frutty [35]
We are going to use this formula:

E° = 0.0592/ n * ㏒K

when E° is the standard state cell potential

and n is number of moles of electrons transferred in the balanced equation

for the reaction of the cell.

Sr(s) + Mg2+ (aq) ↔ Sr2+(aq) + Mg(s)

we can get it by using the given balanced equation, we here have 2 electrons

transferred so, n = 2 

and K the equilibrium constant = 3.69 x 10^17

so, by substitution:

∴ E° = 0.0592 / 2 * ㏒ (3.69 x 10^17)

        = 0.52 V
