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.
It’s 2.0 molecules.
Explanation:
It’s kind of obvious, haha.
Non-living molecules.
Hope it helps! :)
Answer:

Explanation:
Hello,
In this case, considering that the density is considered as the quotient of the mass and volume:

We can easily compute the mass by solving for it as follows:

Best regards.
Explanation:
Magnesium is more reactive then chromium. So, when magnesium hydroxide reacts with chromium (lll) iodide then magnesium displaces chromium.
When magnesium hydroxide and chromium (lll) iodide are mixed together then it results in the formation of magnesium iodide and chromium hydroxide.
The chemical reaction equation is as follows.
