Answer:
its mass
its temperature
Explanation:
The heat capacity of a body is the amount of heat needed to raise that temperature of a body by 1k or 1°C.
It is expresses as:
H = m c Ф
where m is the mass of the body
c is the specific heat of the body
Ф is the temperature change of the body
Specific heat capacity is that heat content needed to raise the temperature of a unit mass of a substance by 1k or 1°C
Heat capacity is also known as heat content;
To solve the problem:
since H = m c Ф
we make the unknown c the subject of the expression;
c = = H / mФ
So to obtain the specific heat capacity, divided the heat capacity by mass and its temperature change.
Answer:
0.238 M
Explanation:
A 17.00 mL sample of the dilute solution was found to contain 0.220 M ClO₃⁻(aq). The concentration is an intensive property, so the concentration in the 52.00 mL is also 0.220 M ClO₃⁻(aq). We can find the initial concentration of ClO₃⁻ using the dilution rule.
C₁.V₁ = C₂.V₂
C₁ × 24.00 mL = 0.220 M × 52.00 mL
C₁ = 0.477 M
The concentration of Pb(ClO₃)₂ is:
