No because they can be seperated differently
The final temperature of the block of brass with a mass of 30.6 g at 87.4°C is 30.82°C.
SPECIFIC HEAT CAPACITY:
- The amount of heat absorbed or released by a substance can be calculated using the following formula:
- (m × c × ∆T) water = - (m × c × ∆T) metal
According to this question;
METAL:
- m = 30.6g
- c = 0.380 J/g°C
- ∆T = T - 87.4°C
WATER:
- m = 62.3g
- c = 4.184J/g°C
- ∆T = T - 28.3°C
- 62.3 × 4.184 × (T - 28.3) = - {30.6 × 0.380 × (T - 87.4)}
- 260.7T - 7376.8 = - {11.63T - 1016.3}
- 260.7T - 7376.8 = -11.63T + 1016.3
- 260.7T + 11.63T = 1016.3 + 7376.8
- Therefore, the final temperature of the block of brass with a mass of 30.6 g at 87.4°C is 30.82°C.

THE QUESTION SHOULD BE
Write the equilibrium constant expression, Kc, for the following reaction: If either the numerator or denominator is 1, please enter 1 CaCO3(s).
CaCO3(s) <=> Ca2+(aq) + CO32-(aq)
Write the mathematical form of the concentration of the products, then divide it by the concentration of the reactants as follows
Kc =[Ca2+]^1 . [CO32-]^1 / [CaCO3]^1
