In a group of water molecules, where do hydrogen bonds form?
ollegr [7]

Answer:

Water molecules forming hydrogen bonds with one another. The partial negative charge on the O of one molecule can form a hydrogen bond with the partial positive charge on the hydrogens of other molecules. Water molecules are also attracted to other polar molecules and to ions.

Explanation: Water molecules forming hydrogen bonds with one another. The partial negative charge on the O of one molecule can form a hydrogen bond with the partial positive charge on the hydrogens of other molecules. Water molecules are also attracted to other polar molecules and to ions.

<u>Answer:</u> The value of K_p is 324

<u>Explanation:</u>

We are given:

Initial pressure of S_8(g) = 1.00 atm

The chemical equation for the conversion of S_8(g) to S_2(g) follows:

                  S_8(g)\rightleftharpoons 4S_2(g)

<u>Initial:</u>          1

<u>At eqllm:</u>    1-x       4x

We are given:

Equilibrium partial pressure of S_8(g)=0.25atm

Evaluating the value of 'x', we get:

\Rightarrow (1-x)=0.25\\\\\Rightarrow x=1-0.25=0.75

The expression of K_p for the above reaction follows:

K_p=\frac{(p_{S_2})^4}{p_{S_8}}

p_{S_2}=4x=(4\times 0.75)=3atm

p_{S_8}=0.25atm

Putting values in above expression, we get:

K_p=\frac{3^4}{0.25}\\\\K_p=324

Hence, the value of K_p is 324

What volume in liters will be occupied by 1.20 moles of helium gas at a pressure of 3.675 atm and 100*C?
lesya [120]

Answer:

V = 121.82 L

Explanation:

Given data:

Number of moles of gas = 1.20 mol

Pressure of gas = 3.675 atm

Temperature = 100°C

Volume occupied = ?

Solution:

Formula:

General gas equation:

PV = nRT

R = general gas constant.

Now we will convert the temperature into kelvin.

100+273 = 373 K

V = nRT/P

V = 1.2 mol × 0.0821 atm.L/mol.K × 373 K / 3.675 atm

V = 447.68 / 3.675 atm

V = 121.82 L
