Hello! So I need help with these neutralization reactions and its fill in the blank. The question asks,
Likurg_2 [28]

The balanced equation for the neutralization reactions is as below.

<h3>Balancing chemical reaction equations</h3>

In order for chemical equations to be balanced, the number of atoms of each element before and after the reaction must be equal.

Thus:

  • HBr + KOH --- > KBr + H_2O
  • 3HF + Fe(OH)_3 --- > 3 H_2O + FeF_3
  • 2HCl + Ca(OH)_2 --- > CaCl_2 + 2H_2O

When 943 J of heat is added to 10 grams of oil at 28˚C , the temperature increases to 89˚C. What is the specific heat of the oil
IgorLugansk [536]

Answer: 1.55 Jg°C

Explanation:

The quantity of Heat Energy (Q) required to heat a substance depends on its Mass (M), specific heat capacity (C) and change in temperature (Φ)

Thus, Q = MCΦ

Since,

Q = 943 joules

Mass of oil = 10g

C = ? (let unknown value be Z)

Φ = (Final temperature - Initial temperature)

= 89°C - 28°C = 61°C

Then, Q = MCΦ

943 J = 10g x Z x 61°C

943J = 610g°C x Z

Z = (943J / 610g°C)

Z = 1.55 Jg°C

Thus, the specific heat of the oil is 1.55 Jg°C
