No, CaCl2 is calcium chloride while Ca Cl2 refers to calcium and chlorine existing as separate elements. The space between "Ca" and "Cl2" indicates that they are not chemically combined.
The balanced chemical reaction of hydrochloric acid (HCl) reacting with calcium (Ca) is: 2HCl + Ca -> CaCl2 + H2
Calcium chloride (CaCl2) is composed of one calcium atom (Ca) and two chloride atoms (Cl), making the percentage of calcium chloride in CaCl2 36.11% calcium and 63.89% chloride.
The molar mass of CaSO4 is 136.14 g/mol. The molar mass of Ca in CaSO4 is 40.08 g/mol. To find the percent composition of Ca by mass, divide the molar mass of Ca by the molar mass of CaSO4 and multiply by 100. This gives a percent composition of approximately 29.4%.
The balanced equation for the reaction between calcium (Ca) and hydrochloric acid (HCl) is: Ca + 2HCl -> CaCl2 + H2
To calculate the mass percent of CaCl2 in water, first find the total mass by adding the mass of CaCl2 (5.0 g) and the mass of water (95.0 g), which equals 100.0 g. The mass percent of CaCl2 is then (5.0 g / 100.0 g) x 100% = 5.0%.

The balanced equation for the reaction between calcium (Ca) and chlorine (Cl2) to form calcium chloride (CaCl2) is: 2Ca + Cl2 -> 2CaCl2
The chemical reaction of calcium (Ca) with hydrochloric acid (HCl) is: Ca + 2HCl -> CaCl2 + H2. This reaction results in the formation of calcium chloride (CaCl2) and hydrogen gas (H2).
The balanced equation for the reaction between calcium (Ca) and hydrochloric acid (HCl) is: Ca + 2HCl -> CaCl2 + H2
The molar mass of Ca(OH)2 is 74.1 g/mol. The mass of oxygen in one mole of Ca(OH)2 is 32.0 g (2 oxygen atoms in the formula). The percent by mass of oxygen in Ca(OH)2 is (32.0 g / 74.1 g) x 100% = 43.2%.
Ca + Cl + Cl = 40.078 +35.453 + 35.453 = 110.984 .89 / 110.984 = 0.008019
The gram formula mass of CaCl2 is approximately 110.98 g/mol. This is calculated by adding the atomic masses of the elements in the compound, which are 40.08 g/mol for calcium (Ca) and 35.45 g/mol for each chlorine (Cl) atom.
The balanced equation for the reaction of hydrochloric acid (HCl) with calcium (Ca) is: 2HCl + Ca -> CaCl2 + H2.
