Answer:
i am unique and have a specific number in the periodic table
Not sure about the last one, but I think the percent composition of zinc would be ~ 42.8232
I think it’s oxygen and carbon
Specific heat capacity is the required amount of heat per unit of mass in order to raise teh temperature by one degree Celsius. It can be calculated from this equation: H = mCΔT where the H is heat required, m is mass of the substance, ΔT is the change in temperature, and C is the specific heat capacity.
H = m<span>CΔT
2501.0 = 0.158 (C) (61.0 - 32.0)
C = 545.8 J/kg</span>·°C
