The formula weight of CuCl is: 98.999
<span>Percent compositions are usually weight percent (abbreviated w/o). </span>
<span>Since CuCl has one mole of each element, the calculation is simple. </span>
<span>For Cu it is: (63.546 / 98.999) x 100% = 64.189 w/o </span>
<span>For Cl it is 100.000 - 64.189 = 35.811 w/o </span>
Explanation:
What is the purpose of the scientific method?
<em><u>ans/</u></em>
the goal of any scientific method is to solve a problem or to better understand an observed event.
b.
i. What does the law of conservation of energy say?
<em><u>ans/</u></em>
The law of conservation of energy states that energy can neither be created nor destroyed - only converted from one form of energy to another.
ii. List two different kinds of energy.
<em><u>ans/</u></em>
Potential energy.
Kinetic energy.
iii. What does the law say about changes energy can undergo?
<em><u>ans/</u></em>
The implication of the Law of Conservation of Energy is that for any energy conversion, if a certain type, or form, of energy gets reduced by a certain amount, then another type of energy must increase by the same amount.
