Single replacement
Synthesis
Decomposition
Double Replacement

Which factor is affecting the rate at which H20 is reacting w/Alka-Seltzer?

Size or surface area of reactant
Concentration of reactant
Temperature of reactant THIS ONE

Of the answers listed I would choose decomposition. I think oxidation is a better term.

I have problems with the second question. What are you calling the reactant? First BOTH H2O and ALKASELTZER are reactants. So temperature affects the solvent (H2O) but surface area affects the alkaseltzer tablet.

The type of reaction between H2O and C16H17NaO14 = C02 + H20 + C2H3NaO3 is a double replacement reaction.

Regarding the factors affecting the rate at which H2O is reacting with Alka-Seltzer, the correct answer is the temperature of the reactant.

To determine the type of reaction, you can break down the given chemical equation and analyze the changes in the chemical species involved. In the given equation, H2O and C16H17NaO14 are reacting to form CO2, H2O, and C2H3NaO3. By examining the reactants and products, we can conclude that this is a decomposition reaction. This reaction breaks down the compounds C16H17NaO14 into three different compounds: CO2, H2O, and C2H3NaO3.

Regarding the factor affecting the rate at which H2O is reacting with Alka-Seltzer, there are three potential factors to consider: the size or surface area of the reactant, the concentration of the reactant, and the temperature of the reactant. Among these factors, the temperature of the reactant is the one that affects the rate of the reaction.

Increasing the temperature of the reactants generally leads to an increase in the rate of the reaction. This is because temperature affects the kinetic energy of particles, making them move faster and increasing the frequency of effective collisions between the reactant molecules. Consequently, more successful collisions lead to a higher rate of reaction. Therefore, in the case of the reaction between H2O and Alka-Seltzer, an increase in temperature would enhance the reaction rate.
