The temperature change is 96.9 °C
Using Q = mcΔT where Q = quantity of energy applied = 250 J, m = mass of gold = 20 g, c = specific heat capacity of gold = 0.129 J/g °C and ΔT = temperature change
Since we require the temperature change, making ΔT subject of the formula, we have
ΔT = Q/mc
substituting the values of the variables into the equation, we have
ΔT = 250 J/(20 g × 0.129 J/g °C)
ΔT = 250 J/(2.58 J/°C)
ΔT = 96.89 °C
ΔT ≅ 96.9 °C
So, the temperature change is 96.9 °C

Answer:
dissolved in the solute
Explanation:
A solvent is the component that dissolves the solute and is present in larger amount. The type of solution is determined by the state of the solute and solvent. If you have NaCl, a solid, dissolved in water, a liquid, the type of solution is a solid/liquid solution.
the answer is D
Because x can equal any number divided by 2 +1
