12. The specific heat of copper is 0.385 J/g • °C. Which equation would you use to calculate the amount of heat needed to raise the temperature of 0.75 g of copper from 7°C to 29°C? (1 point)Q = 0.385 J/g • °C x (29°C – 7°C)
Q = 0.75 g x 0.385 J/g • °C x 29°C
Q = 0.75 g x 0.385 J/g • °C x 22°C
Q = 0.75 g x 0.385 J/g • °C x 7°C

the change in temp is 29-7 = 22
Only one of your choices has 22
hummmm
