Answer:
Specific heat capacity formula
Explanation:
The heat capacity gives the exact heat energy at which a given mass of a substance is heated from one temperature to another.
This formula can help determine how much heat is gained or lost during the reaction and is given by:
Q = mcΔT
where:
Q = heat energy in Joules or Calories
m - mass of the substance (g)
c = Specific heat capacity (J/kg°C)
ΔT = change in temperature = (final temp - initial temp) (°C)

Answer:
iodine heptafluoride
Explanation:
please mark me as brainlest
Answer is: <span>molarity of this solution is 19,92M.
</span>m(H₂) = 0,95 g.
m(Pd) = 275 g.
d(solution) = 11,7 g/cm³.
m(solution) = 0,95 g + 275 g.
m(solution) = 275,95 g.
V(solution) = m(solution) ÷ d(solution).
V(solution) = 275,95 g ÷ 11,7 g/cm³.
V(solution) = 23,585 cm³ = 0,023585 L.
n(H₂) = m(H₂) ÷ M(H₂).
n(H₂) = 0,95 g ÷ 2,016 g/mol.
n(H₂) = 0,47 mol.
c(solution) = 0,47 mol ÷ 0,023585 L.
c(solution) = 19,92 mol/L = 19,92 M.
