What salt is formed when a solution of calcium hydroxide Ca is neutralized by hydrochloric acid HC1?
the salt formed when a solution of calcium hydroxide is neutralized by hydrochloric acid is calcium chloride. The formula for the calcium chloride formed is CaCl2. Other product formed will be hydrogen gas(H2) and water (H2O). This is because when an acid is neutralized by a hydroxide solution the resultant product should be a salt of the constituent metal(in our case, calcium), hydrogen gas, and water. The water will however not be formed if the mixture is only between a metal in the form of a solid and an acid; in this case only the salt and hydrogen gas are formed.
What is the balanced equation for a hot pack?
The balanced equation for a hot pack typically involves an exothermic reaction. For example, in the case of an instant hot pack containing water and calcium chloride (CaCl2), the reaction can be represented as: CaCl2 + 2H2O -> CaCl2 * 2H2O + heat. This reaction releases heat energy when the calcium chloride dissolves in water.
Do hydrochloric acid react with calcium?
Yes, hydrochloric acid and calcium will react to produce calcium chloride and hydrogen gas. The reaction equation is: 2HCl + Ca → CaCl2 + H2.
What is the percent of a water solution that contains 60 g of calcium chloride and that has a mass of 400 g?
The percent of a solution is calculated by dividing the mass of the solute by the mass of the solution and multiplying by 100. In this case, the percent of the water solution containing 60 g of calcium chloride in a 400 g solution would be (60 g / 400 g) * 100 = 15%.
Why isn't ca cl calcium dichloride?
Calcium forms ionic compounds by giving away two electrons to achieve a stable electron configuration. In the case of calcium chloride (CaCl2), each calcium atom gives away two electrons to two chlorine atoms, resulting in a compound with a 1:2 ratio of calcium to chlorine atoms. If it were calcium dichloride, it would imply a 1:1 ratio, which is not the case in this compound.
What is the mass percent of calcium chloride if 45g of cacl2 is dissolved in 320 g of water?
Mass percent of calcium chloride can be calculated by dividing the mass of calcium chloride by the total mass of the solution (calcium chloride + water) and then multiplying by 100. In this case, the mass percent would be (45g / (45g + 320g)) * 100 ≈ 12.35%.

Calcium chloride is often used to de-ice roads in the winter What volume would 15.7 g calcium chloride occupy?
The density of calcium chloride is approximately 2.15 g/cm3. By dividing the mass by the density, you can calculate the volume. In this case, 15.7 g of calcium chloride would occupy around 7.3 cm3 of volume.
Do hydrochloric acid react with calcium?
Yes, hydrochloric acid and calcium will react to produce calcium chloride and hydrogen gas. The reaction equation is: 2HCl + Ca → CaCl2 + H2.
A solution contains 30 g of calcium chloride in 250 g of water express the mass percent?
Mass percent of calcium chloride in the solution is calculated as (mass of calcium chloride / total mass of solution) * 100. In this case, it would be (30 g / (30 g + 250 g)) * 100 = 10.7%.
What is the balanced equation for a hot pack?

This reaction releases heat energy when the calcium chloride dissolves in water.
What is the percent of a water solution that contains 60 g of calcium chloride and that has a mass of 400 g?
The percent of a solution is calculated by dividing the mass of the solute by the mass of the solution and multiplying by 100. In this case, the percent of the water solution containing 60 g of calcium chloride in a 400 g solution would be (60 g / 400 g) * 100 = 15%.

What is the chemical name for calcium salt?
The chemical name for calcium salt is calcium chloride (CaCl2).
How many grams of calcium chloride will you add to 250mL of water to make a 0.236 M solution?
To calculate the amount of calcium chloride to add, you first need to determine the number of moles required using the formula Molarity = moles/volume. In this case, 0.236 M = moles/0.25 L. This gives you 0.059 moles of calcium chloride needed. Since calcium chloride has a molar mass of 110.98 g/mol, you will need 6.58 grams of calcium chloride to make a 0.236 M solution in 250 mL of water.
Is calcium sulphate a compound or an element?
Calcium sulfate is a compound, not an element. It is made up of calcium (Ca) and sulfate (SO4) ions bonded together.
Is calcium carbonate a solute?
Yes, calcium carbonate can be considered a solute when it is dissolved in a solvent, such as water. In this case, calcium carbonate molecules disperse in the liquid to form a homogenous solution.
