Boyle's law gives the relationship between pressure and volume of gas. 
It states that at constant temperature, pressure is inversely proportional to volume of gas.
PV = k
where P - pressure, V - volume and k - constant 
P1V1 = P2V2
where parameters for the first instance are on the left side and parameters for the second instance are on the right side of the equation 
substituting these values in the equation 
4.00 atm x 500 L = 8.0 atm x V
V = 250 L 
new volume is 250 L

Given the reaction: Ca + 2H2O → Ca(OH)2 + H2 What is the total number of moles of Ca needed to react completely with 4.0 moles o
DiKsa [7]

<u>Answer:</u> The number of moles of calcium metal required is 2.0 moles.

<u>Explanation:</u>

We are given:

Moles of water reacted = 4.0 moles

The given chemical reaction follows:

Ca+2H_2O\rightarrow Ca(OH)_2+H_2

By Stoichiometry of the reaction:

2 moles of water is reacted with 1 mole of calcium metal

So, 4.0 moles of water will react with = \frac{1}{2}\times 4.0=2.0mol of calcium metal

Hence, the number of moles of calcium metal required is 2.0 moles.

Consider the following reaction where K. = 154 at 298 K: 2NO(g) + Brz(9) 2NOBr(g) A reaction mixture was found to contain 2.69x1
bekas [8.4K]

Explanation:

2NO(g) + Br_2(g)\rightleftharpoons 2NOBr(g)

Equilibrium constant of reaction = K=154

Concentration of NO = [NO]=\frac{2.69\times 10^{-2} mol}{1 L}=2.69\times 10^{-2} M

Concentration of bromine gas = [Br_2]=\frac{3.85\times 10^{-2} mol}{1 L}=3.85\times 10^{-2} M

Concentration of NOBr gas = [Br_2]=\frac{9.56\times 10^{-2} mol}{1 L}=9.56\times 10^{-2} M

The reaction quotient is given as:

Q=\frac{[NOBr]^2}{[NO]^2[Br_2]}=\frac{(9.56\times 10^{-2} M)^2}{(2.69\times 10^{-2} M)^2\times 3.85\times 10^{-2} M}

Q=328.06

Q>K

The reaction will go in backward direction in order to achieve an equilibrium state.

1. In order to reach equilibrium NOBr (g) must be produced.  False

2. In order to reach equilibrium K must decrease. False

3. In order to reach equilibrium NO must be produced. True

4. Q. is less than K . False

5. The reaction is at equilibrium. No further reaction will occur. False
