We can use the heat equation,
Q = mcΔT
Where Q is the amount of energy transferred (J), m is the mass of the substance (kg), c is the specific heat (J g⁻¹ °C⁻¹) and ΔT is the temperature difference (°C).
Q = 322 J
m = 100.0 g
c = ?
ΔT = (50 - 25)
°C = 25 °C
By applying the formula,
322 J = 100.0 g x c x 25 °C
c = 322 J / (100.0 g x 25 °C)
c = 0.1288 J g⁻¹ °C⁻¹
Hence, the specific heat of gold is 0.1288 J g⁻¹ °C⁻¹.
It can cause the alligators to become endangered or extinct because if there are not enough fertile males then they can not reproduce and will eventually die out.
The formula for pOH is -log(M)
So, all we need to do is plug in that number! -log(4.5x10^-3)
That gives us 2.3, so the pOH is 2.3 :)
