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.

If the density of a metal bar is 3.47 g/mL and volume is 30 mL, calculate the mass of the metal bar in grams (g). Show the steps
Hitman42 [59]

Answer:

m=104.1g

Explanation:

Hello,

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

\rho =\frac{m}{V}

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

m=V*\rho =30 mL*3.47g/mL\\\\m=104.1g

Best regards.

the molecular equation to aqueous solutions of magnesium hydroxide and chromium (lll) iodide are mixed
Llana [10]

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.

    3Mg(OH)_{2} + 2CrI_{3} \rightarrow 3MgI_{2} + 2Cr(OH)_{3}
