If the same amount of energy in the form of heat is added to 8.9 g samples of each of the metals below, which metal will undergo
1 answer:
Answer:
Explanation:
The metal with the highest specific heat capacity will undergo the most temperature change.
Specific heat capacity is the amount of heat supplied to a unit mass of a substance to cause a temperature change of 1°C.
A very good conductor of heat will have low specific heat capacity. This implies that less heat will be required to cause a monumental change in its temperature.
C =
where C is specific heat
H is the amount of heat supplied
m is the mass
t is the temperature
We see that since both H and m for the two metals are the same, specific heat is inversely proportional to temperature change.
The lower the heat capacity, the higher the temperature change.

Answer: Moles of hydrogen required are 4.57 moles to make 146.6 grams of methane, .
Explanation:
Given: Mass of methane = 146.6 g
As moles is the mass of a substance divided by its molar mass. So, moles of methane (molar mass = 16.04 g/mol) are calculated as follows.
The given reaction equation is as follows.
This shows that 2 moles of hydrogen gives 1 mole of methane. Hence, moles of hydrogen required to form 9.14 moles of methane is as follows.
Thus, we can conclude that moles of hydrogen required are 4.57 moles to make 146.6 grams of methane, .
