See what you get.) The formula for slope<span> is sometimes referred to as "</span>rise over<span> run", because the fraction consists of the "</span>rise<span>" (the change in y, going up or down) divided by the "run" (the change in x, going from left to the right).</span>
If you need help reading it then ask away, the two answers end up being, 2Na, and 2NO3
When the Heat gain or lose = the mass * specific heat * ΔT
and when we have the mass of gold coin= 40 g
and the specific Heat of gold= 0.13 J/g°
and ΔT = (Tf- Ti) = 10°C - 50°C = -40 °C
so by substitution:
∴Heat H = 40 g * 0.13 J/g° * -40
= - 208 J
