the mass of 1 mole of the element is used as a conversion factor to convert grams to moles
the line graphs and pie charts are used for different kinds of analysis
a) pie chart : it compares the portion of one thing in a group of different things
For example out of 100 people how many have brown hairs , how many have black hairs and how many have white hairs
or
like population division out of 100 into different parts
b) line graphs: they show the relation ship between two variables
Example: effect of temperature on volume
it tells the trend in any property with respect to some other quantity or quality parameter.
Q=mcdeltaT. use this formula and find the answer.
Answer:
Option c is the correct one <em>sorry</em><em> </em><em>this</em><em> </em><em>is</em><em> </em><em>not</em><em> </em><em>the</em><em> </em><em>correct</em><em> </em><em>one</em>
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
