Answer:
HCl and CaCl2
Explanation:
Calcium hydroxide acts as a base, thus requiring an acid for neutralization.
HCl functions as an acid, which can neutralize calcium hydroxide when they react together.
The resulting salt will be calcium chloride (CaCl2).
The interaction between calcium hydroxide and HCl yields Ca(OH)Cl and CaCl2.
Here, Ca(OH)Cl exists as a solution and calcium chloride serves as a base.

To tackle this problem, one must first determine the specific heat of water, which is the energy required to raise the temperature of 1 g of water by 1 degree C. The relationship is given by the formula q = c X m X delta T, where q indicates the specific heat of water, m signifies the mass, and delta T denotes the temperature change. The specific heat of water is 4.184 J/(g X degree C). The temperature of the water increased by 20 degrees, therefore: 4.184 x 713 x 20.0 = 59700 J, rounded to 3 significant digits, equals 59.7 kJ. This value indicates the energy required to produce B2O3 from 1 gram of boron. To convert this to kJ/mole, additional calculations are required. The gram atomic mass of Boron is 10.811, so dividing 1 gram of boron by 10.811 results in.0925 moles of boron. Given that 2 moles of boron are needed for the formation of 1 mole of B2O3, dividing the moles of boron by two yields.0925/2 =.0462 moles. Consequently, dividing the energy in KJ by the number of moles provides KJ/mole: 59.7/.0462 = 1290 KJ/mole.
