The metal which will reach the highest temperature is the metal with the lowest specific heat capacity.
<h3>What is the amount of heat added to each metal?</h3>
The amount of heat Q = mcΔT where
- m = mass of metal
- c = specific heat capacity of mateal and
- ΔT = temperature change
<h3>Temperature change of the metal</h3>
Making ΔT subject of the formula, we have
ΔT = Q/mc
Given that Q and m are the same for each metal,
ΔT ∝ 1/c
We see that the temperature change is inversely proportional to the specific heat capacity.
Since the metals are at the same temperature, the metal which will reach the highest temperature is the metal with the lowest specific heat capacity.
So, the metal which will reach the highest temperature is the metal with the lowest specific heat capacity.

Mass of CO₂ evolved : 0.108 g
<h3>Further explanation</h3>
Given
1.205g sample, 36% MgCO3 and 44% K2CO3
Required
mass of CO2
Solution
0.36 x 1.205 g=0.4338 g
mass C in MgCO₃(MW MgCO₃=84 g/mol, Ar C = 12/gmol)
= (12/84) x 0.4338
= 0.062 g
0.44 x 1.205 g = 0.5302 g
Mass C in K₂CO₃(MW=138 g/mol) :
= (12/138) x 0.5302
= 0.046 g
Total mass Of CO₂ :
= 0.062 + 0.046
= 0.108 g
Answer:
A learned behavior is a behavior that develops during an animal's lifetime. Tying one's shoes or solving a math problem are examples of learned behaviors. An inherited behavior is a behavior that an animal is born with. It does not have to be taught. For example, a bird can build a nest for the first time without any help.
