Calculate the number of atoms in 0.316 mol of phosphorus
Nikitich [7]

Answer:

\large \boxed {7.61 \times 10^{23}\text{ atoms}}

Explanation:

1. Molecules of P₄

The molecular formula of phosphorus is P₄.

\text{Molecules of P}_{4} = \text{0.316 mol P}_{4} \, \times \dfrac{ 6.022  \times 10^{23}\text{ molecules P}_{4}}{\text{1 mol P}_{4}} = 1.90 \times 10^{23}\text{ molecules P}_{4}

2. Atoms of P

One molecule of phosphorus contains four P atoms.

\text{Atoms of P} = 1.90 \times 10^{23}\text{ molecules P}_{4} \times \dfrac{\text{4 atoms P}}{\text{1 molecule P}_{4}}\\\\= \large \boxed{\mathbf{7.61 \times 10^{23}}\textbf{ atoms P}}

Alex787 [66]

Answer:

The rate equation for this reaction:

R=k[NH_3]^0

Explanation:

Decomposition of ammonia:

2NH_3\rightarrow N_2+3H_2

Rate law of the can be written as;

R=k[NH_3]^x

1) Rate of the reaction , when [NH_3]=2.0\times 10^{-3} M

1.5\times 10^{-6} M/s=k[2.0\times 10^{-3} M]^x..[1]

2) Rate of the reaction , when [NH_3]=4.0\times 10^{-3} M

1.5\times 10^{-6} M/s=k[4.0\times 10^{-3} M]^x..[2]

[1] ÷ [2]

\frac{1.5\times 10^{-6}M/s}{1.5\times 10^{-6}M/s}=\frac{k[2.0\times 10^{-3}M]^x}{k[4.0\times 10^{-3}M]^x}

On solving for x , we get ;

x = 0

The rate equation for this reaction:

R=k[NH_3]^0

If a reaction mixture initially contains 0.195 m so2cl2, what is the equilibrium concentration of cl2 at 227 ???c?
Aloiza [94]
Missing in your question the K constant value =2.99X10^-7
The reaction equation:
         SOCl2 ⇄ SO2 +Cl2
initial 0.195          0        0
         -X             +X      +X
final  (0.195-X)      X        X

K= [SO2][Cl2]/SOCl2
by substitution
2.99X10^-7 = (X)(X)/(0.195-X)
2.99X10^-7 = X^2 / (0.195-X) by solving this equation 
∴X = 0.00024 = 2.4 X10^-4 
∴[Cl2] = 2.4X10^-4 m
