Step-by-step explanation:
A student investigated the reaction of aqueous potassium hydroxide with two different
acids, acid C and D.
Two experiments were carried out.
Experiment 1
By using a measuring cylinder, 40 cm of aqueous potassium hydroxide was poured into a
conical flask and the initial temperature of the solution was measured.
A burette was filled with acid C up to the 0.0 cm mark.
10 cm of acid C was added to the potassium hydroxide in the flask. The temperature of the
mixture was measured?

Answer:
( 2^3x-1 + 10 ) ÷ 7 = 6 => 2^3x-1+10\7 = 6 => 2^3x-1 + 10 = 42 => 2^3x-1 = 42 - 10 => 2^3x-1 = 32 => 2^3x-1 = 2^5 => 3x - 1 = 5 => 3x = 5 + 1 => 3x = 6 => x = 2
