Answer:
1.553 M^2s^-1
Explanation:
Now let us consider experiments 1,2,3.
In experiment 1 and 2, the concentration of NO is doubled and the initial rate of reaction is quadrupled.
0.575/0.144 = 4
So;
2^2 =4
In experiment 2 and 3
The concentration of reaction of H2 is doubled and the rate of reaction is doubled.
0.575/0.287 = 2
2^1 =2
So we can now write;
Rate =k[NO]^2 [H2]^1
Taking up the first reaction;
0.144 =k [0.475]^2 [0.411]
k = 0.144/ [0.475]^2 [0.411]
k = 1.553 M^2s^-1
Electrons have a mass of 1/1836

Answer:
<h3>The answer is 12.5 g</h3>
Explanation:
The mass of a substance when given the density and volume can be found by using the formula
mass = Density × volume
From the question we have
mass = 2.5 × 5
We have the final answer as
<h3>12.5 g</h3>

The complete chemical formula for the unknown compound will be 
<h3>Chemical formula</h3>
The chemical formula of the compound is
and x is supposed to be a whole number.
In the analysis, C = 2.22 moles and H = 6.7 moles
Dividing both by the smallest: C = 1 and H = 3
Thus, the empirical formula of the compound will be 
But since the compound is
, it means both C and H are multiplied by 2.
The chemical formula will, therefore, be
