I honestly have no clue on this one
Answer: a tornado doesnt have an eye in the middle and its cause by wind and air but a hurricane is way different then a tornado a hurricane is only perduce by air and the force of it can damage more than a tornado and the hurricane also has an eye in the middle and its bigger than a tornado so its C
Explanation:
Answer:
Heat change = 3.77kJ
Explanation:
T1 = 25°C
Mass = 65g
T2 = 30°C
specific heat capacity of water = 4.184J/g°C
Heat energy = ?
Heat energy = MC∇T
Heat energy (Q) = MC(T2 - T1)
Q = 65 * 4.184 * (30 - 15)
Q = 251.04 * 15
Q = 3765.6J
Q = 3.77KJ
The heat change during the reaction was 3.77kJ
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.
