A 10-ft moving truck has a volume capacity of 402 cubic feet, which is equivalent to 1.138 x 10^7 milliliters. What
ELEN [110]

Answer: The mass of silver is 1.19 X 10^14 M g

Explanation: The volume of the truck is 402 cubic feet or 1.138 x 10⁷ mm.

The density of silver is 10.49 g/mL.

We need to find the mass of silver that will fit in this moving truck. Density equals mass divided by volume. So,

<h2>d= m/v where m= mass m= d x V</h2><h2>M=10.49 g/mL X 1.138 X 10∧7 mL</h2>

M=119376200 g  1 gram=10⁻⁶ Megagram 119376200= 1.19 X 10^14 Mg hence the mass of silver is 1.19 X 10^14 M g hopefully this will help you please mark me as brainlist

Consider: CO(g) + Cl2 (g) ⇌ COCl2 (g) Kc = 1.2×103 at 395 °C. If the equilibrium concentrations of Cl2 and COCl2 are the same at
ad-work [718]

Answer : The equilibrium concentration of CO in the reaction is, 8.3\times 10^{-4}M

Explanation :

The given chemical reaction is:

CO(g)+Cl_2(g)\rightleftharpoons COCl_2(g)

The expression for equilibrium constant is:

K_c=\frac{[COCl_2]}{[CO][Cl_2]}

As we are given:

Concentration of Cl_2 at equilibrium = Concentration of COCl_2

So,

K_c=\frac{[Cl_2]}{[CO][Cl_2]}

K_c=\frac{1}{[CO]}

1.2\times 10^3=\frac{1}{[CO]}

[CO]=8.3\times 10^{-4}M

Therefore, the equilibrium concentration of CO in the reaction is, 8.3\times 10^{-4}M
