Answer:
a) The metal with the higher heat capacity.
Explanation:
The heat (Q) absorbed by a metal can be calculated using the following expression.
Q = c × m × ΔT
where,
c is the specific heat capacity of the metal
m is the mass of the metal
ΔT is the change in the temperature
Q = c × m × ΔT
ΔT = Q/ c × m
Considering both metals have equal mass (m) and are subject to the same amount of heat (Q), the change in the temperature is inversely proportional to the specific heat capacity. The metal with the higher specific heat capacity will undergo the smallest change in temperature.
Answer:
Explanation:
Data:
Actual yield = 16.8 g
Theoretical yield = 49.7 g
Calculation:
The mantle layer is more dense closest to the core.
The unit ppm (parts per million) should be numerically equal to the unit of mg/L (milligram per liter). First, we determine the volume of the stock solution in L.
V = (100 mL)(1 L/1000 mL)
V = 0.1 L
Then, the equation that would allow us to determine the value of mass is,
C = m/V
where C is concentration, m is mass, and V is the volume.
Substituting the known values,
2 = m/ 0.1
The value of m from the equation is 0.2.
Answer: 0.2 mg
