Answer:

The volume of water vapor increases.

Explanation:

Pressure, concentration, and temperature all affect the equilibrium position of chemical reactions in a closed system such as this one. Increasing HCl increases the pressure in the system. It favors the forward's reaction because this favors a reduced overall pressure in the system. The products have a combined 3 moles of gases while the reactants have a combined 5 moles of gases.

Using dimensional analysis, how many seconds are in 1.2 days?

julsineya [31]

Answer:

103,680 seconds

Explanation:

1.2 days x $\frac{24 hours}{1 day} \frac{60 minutes}{1 hour} \frac{60 seconds}{1 minute}$

(1.2)(24)(60)(60) = 103,680 seconds

What is the density of CHCL3 vapor at 1.00atm and 298K?

Advocard [28]

Answer:

4.8 g/mL is the density of chloroform vapor at 1.00 atm and 298 K.

Explanation:

By ideal gas equation:

$PV=nRT$

Number of moles (n)

can be written as: $n=\frac{m}{M}$

where, m = given mass

M = molar mass

$PV=\frac{m}{M}RT\\\\PM=\frac{m}{V}RT$

where,

$\frac{m}{V}=d$ which is known as density of the gas

The relation becomes:

$PM=dRT$ .....(1)

We are given:

M = molar mass of chloroform= 119.5 g/mol

R = Gas constant = $0.0821\text{ L atm }mol^{-1}K^{-1}$

T = temperature of the gas = $298K$

P = pressure of the gas = 1.00 atm

Putting values in equation 1, we get:

$1.00atm\times 119.5g/mol=d\times 0.0821\text{ L atm }mol^{-1}K^{-1}\times 298K\\\\d=4.88g/L$

4.8 g/mL is the density of chloroform vapor at 1.00 atm and 298 K.
