<h3><u>Answer;</u></h3>
C. increasing the surface area of Fe2O3
<h3><u>Explanation;</u></h3>
- The rate of reaction refers to the speed at which products are formed from reactants.
- The rate of any chemical reaction depends on a number of factors which include, surface area, temperature, concentration of reactants among others.
- <em><u>When solids and liquids react, increasing the surface area of the solid will increase the rate of reaction. Thus, decrease in the size of particles causes an increase in the total surface area of the solid and therefore increasing the rate of reaction.</u></em>
Shrivel/shrink and become flaccid because the water inside of the potato leaves the potato and joins the salt water due to the lower concentration in the salt water
0.986 moles of CaO are formed when 98.60 g of decomposes.
<h3>What are moles?</h3>
A mole is defined as 6.02214076 × of some chemical unit, be it atoms, molecules, ions, or others.
Number of moles of CaCO3 =
Number of moles of CaCO3 =
= 0.986 moles
Reaction:
→
Since the reaction is 1:1:1.
So 0.986 moles of CaO are formed.
