What amount of heat absorbs 50 g of steel (ce = 0.115 cal / g. ° C) that

does its temperature vary by 25 ° C?

Answer:

143.75cal

Explanation:

Given parameters:

Mass of steel  = 50g

Specific heat capacity of the steel  = 0.115cal/g°C

Temperature  = 25°C

Unknown:

Amount of heat = ?

Solution:

The amount of heat to cause this temperature change is dependent on mass and specific heat capacity of the substance.

  Amount of heat  = m C (ΔT)

m is the mass

c is the specific heat capacity

ΔT is the temperature change

 Now insert the parameters and solve;

  Amount of heat  = 50 x 0.115 x 25

  Amount of heat  = 143.75cal

What is the relationship among solutions solutes and solvents
jenyasd209 [6]

Answer:

Solvents are substances in which solutes dissolves while solutes are substances that dissolve in solvents and solutions result from mixing solvents and solutes.

Explanation:

  • A solvent is a substance such as water that dissolves a solute.
  • A solute is a substance that dissolves in a solvent. For example, when sodium chloride dissolves in water, sodium chloride is the solute and water is the solvent.
  • A solution, on the other hand, results from combining a solute and a solvent. Therefore, a mixture of water and sodium chloride forms the solution.

Which compound is produced when HCl(aq) is neutralized by Ca(OH)2(aq)?
kiruha [24]

<u>Answer:</u> The correct answer is Option 1.

<u>Explanation:</u>

Neutralization reaction is defined as the reaction in which acid reacts with a base to produce a salt along with water.

Here, HCl is an acid and Ca(OH)_2 is a base. When these two compounds react, the salt obtained is calcium chloride.

The equation for the above reaction is given by:

2HCl(aq.)+Ca(OH)_2(aq.)\rightarrow CaCl_2(s)+2H_2O(l)

Hence, the correct answer is Option 1.
