Answer:
The temperature of the system once the equilibrium has been reached = 372.55K
Explanation:
Heat capacity of gold = 129 J/Kg*c.
Heat capacity of water
4,184 J/Kg*c.
Mass of gold = 75g = 0.075Kg
Mass of water = 200g = 0.2Kg
From conservation of energy
m1×C1×(t11 - t2) = m2×C2×(t2- t21)
Substituting we have
0.075 × 129×(1000-t2) = 0.2× 4184×( t2 -300) =solving for t2, we have
933.55×t2 = 347790
or t2 = 372.55K
The temperature of the system once the equilibrium has been reached = 372.55K

Answer:
Explanation:
An object decreases in size due to the collision of materials. An object increases in size due to the addition of materials. Gas particles are formed from solar nebula materials.
Answer:
Ca²⁺ and Cl⁻
Explanation:
In a chemical reaction, spectator ions are ions that <em>are not involved in the reaction</em>, that means are the same before and after the reaction.
In water, calcium hydroxide, Ca(OH)₂ is dissociated in Ca²⁺ and OH⁻. Also, hydrochloric acid, HCl, dissociates in H⁺ and Cl⁻. The reaction is:
Ca²⁺ + 2OH⁻ + 2H⁺ + 2Cl⁻ → 2H₂O + Ca²⁺ + 2Cl⁻
<em>The ions that react are H⁺ and OH⁻ (Acid and base producing water)</em>
<em />
And the ions that are not reacting, <em>spectator ions</em>, are:
<h3>Ca²⁺ and Cl⁻</h3>
