It is physical change because ? has changed alone not with chemicals
Answer:
The chemical reaction is a Double Displacement
Explanation:
Balance the reaction of KOH + AlCl3 = KCl + Al(OH)3
The final temperature of the mass of gold is 737 °C.
<h3>What is the specific heat capacity of gold?</h3>
The specific heat capacity of gold is 0.126 J/g/K
The final temperature, T2 of the gold is calculated as follows:
T2 = T + Q/mc
where;
T is initial temperature, m is mass, and c is specific heat capacity of gold.
T2 = 27 + 2.3 x 1000/(25 x 0.126)
T2 = 737 °C
Therefore, the mass and heat capacity of gold determines its final temperature.
