Calcium chloride is a hygroscopic compound and may absorb water from surroundings.
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.
Yes. When most metals react with dilute hydrochloric acid, metal chloride and hydrogen gas are the products. In the case of calcium, calcium chloride and hydrogen gas are produced.
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.
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%.
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.
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%.

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.
Yes. When most metals react with dilute hydrochloric acid, metal chloride and hydrogen gas are the products. In the case of calcium, calcium chloride and hydrogen gas are produced.
The solution has a total mass of 30 + 250 = 380 g. The mass percent of calcium chloride in this solution is 100(30/380) = 7.9 %, to the justified number of significant digits.

The name for calcium carbonate is calcium carbonate. The formula is CaCO3
Molarity is moles of solute / liters of solvent. Plugging in the data: 0.236M = x / 0.250L; x = (0.236M)(0.250L) = 0.0590 moles of CaCl2. The molecular weight of CaCl2 is 40.1 + 2(35.5) = 111.1 g / mole. The mass of CaCl2 = (MW)(moles) = (111.1g/mole)(0.0590moles) = 6.55g
Calcium sulphate is a compound. A compound is created when two or more elements are combined such as calcium and sulphide or sodium and chloride in the case of table salt.
It is a very good question indeed! You see calcium chloride in which calcium is attached to two chlorine atoms is water soluble and vice versa sodium carbonate in which two sodium atoms are attached to one carbonate is soluble. In one to one proportion, calcium chloride molecule is insoluble. Now the answer for this question may go like this. In case of calcium chloride calcium gives one electron to each of chlorine atom. Now both chlorine atoms would have one negative charge. So both of them will repel each other and form the ions of calcium and two chlorine. Thus making them soluble. In case of sodium carbonate, two sodium atoms give electrons to carbonate. Now both sodium ions become positively charged and and would repel each other. So they would form ions along with carbonate. So sodium carbonate has become soluble. Now in case of calcium carbonate, calcium would like to give away 2 electrons but carbon becomes much electrically negative if it takes the electrons. So in this case no repelling force is there to help the metal, it surrenders and form sort of covalent bond and thus ions are not formed. So calcium carbonate is insoluble in water.
