Now, notice that for every #1# mole of calcium fluoride that takes part in the reaction, the reaction consumes #1# mole of sulfuric acid and produces #2# moles of hydrogen fluoride.

Calcium hydroxide is obtained from calcium oxide...and in terms of the lime cycle (which results in the preparation of mortar, and cement, and concrete), this is a very important, and well-studied reaction.

Jan 7, 2018 · The subscript in the chemical formula represents how many such atom there are....for #H_2O#, there are 2 hydrogen atoms, and 1 oxygen in the molecule. For #C_2H_6#, there are 2 …

1.80 * 10^(22) "atoms" You should know that in order to get from grams to atoms, you need to go through moles first. So you will need to use the molar mass of barium chloride to convert the sample …

The only thing to watch out for is the fact that the concentrations of the calcium cations are not given in the same unit, so you must convert one of them to the units of the other

Explanation: Since the problem gives us the explicit formula, we can simply plug in the values for n: For #a_1#, we know #n=1#, so: #a_1= (-1)^1/ (1)^2=-1# For #a_2 ...
