Answer:
Explanation:
Subscripts are numbers written after elements, subscripts indicate how many of each atom there are in a compound.
Answer:
C. the carbons in ethene are linked by double bonds
Explanation:
The reason for the lack of free rotation about the carbons of ethene is that they are linked with with double bonds.
In single bonds afforded with the ethane compound, there is free rotation.
The double bonds confer a special restriction on the rotational potential of the bonded atoms round the carbon.
Answer:
that would be true you place it outside the hexagon
Explanation:
Rate = k[A] = first order reaction
<h3>Further explanation</h3>
Given
Rate law
Required
A first-order reaction
Solution
The rate law : equation for the rate of chemical reaction
For reaction
aA + bB ⇒ C
The rate : r = k[A]ᵃ[B]ᵇ
The sum of exponents(a+b) is the reaction order
From the choice :
a. a+b = 2, second order reaction
b. a+b = 3, third order reaction
c. a+b = 4, fourth order reaction
d a+0 = 1, first order reaction
