Answer:

In chemistry, there are three definitions in common use of the word base, known as Arrhenius bases, Brønsted bases and Lewis bases. All definitions agree that bases are substances which react with acids as ... A ...

Acids are species with pH less than 7, while bases those with pH greater than 7. ... Using Arrhenius' definition, acids are those that produce the hydrogen ion when dissolved in water ( ) while bases produce the hydroxide ion ( ). These ions, when in water, act as charge carriers and can hence conduct electricity.

Acid–base reactions require both an acid and a base. ... For example, according to the Arrhenius definition, the reaction of B If inorganic, determine whether the compound is acidic.

What is the theoretical yield of a reaction?
mestny [16]
I think it's D, because theoretical yield is like, the yield you'd get if 100% of the reactants formed to make product. Well that's how I think of it, but it has something to do with limiting reagents and stuff. Sorry this isn't a really detailed explanation.

Hydrochloric acid reacts with calcium to form hydrogen and calcium chloride. if 100 grams of hydrochloric acid reacts with 100 g
natita [175]
The balanced chemical reaction is:

2HCl + Ca = CaCl2 + H2

We are given the amount of the reactants to be used for the reaction. These values will be the starting point of our calculations.

100 g HCl ( 1 mol HCl / 36.46 g HCl ) = 2.74 mol HCl

100 g Ca ( 1 mol Ca / 40.08 g ) = 2.08 mol Ca

From the reaction, the mole ratio of the reactants is 2:1 where every 2 moles of hydrochloric acid, 1 mole of calcium is required. Therefore, the limiting reactant for this case is calcium.
