<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>
Oxygen is more ELECTRONEGATIVE than Hydrogen, which means that the electrons in the atom are coaxed more toward the Central Oxygen atom. Because of this, the charge is not evenly distributed among the molecule, causing it to have positive and negative sides. This is what we call a POLAR molecule.
Yes, when molten candle wax solidifies it is a chemical reaction
<u>Explanation:</u>
Basically Wax is crystalline so once the candle light melts it freezes taking back the solid state to the room temperature.
When the room temperature is below the freezing point, the liquid candle wax, turns into solid state again, therefore this process is called solidification. The process of freezing or solidification is a process when an object turns liquid and freezes back to solid state.
Indeed, Yes, when molten candle wax solidifies it is a chemical reaction
