100mL of water is poured into a Styrofoam cup. 4g of solid NaOH is added to this cup. A reaction occurs, and the change in temperature is 9.2 degrees celcius. Calculate the amount of heat released.
I am almost certain that q=smt will be used here, but I am unsure of a few things:
Do i need to account for the mass of water in my mass variable?
Do i need to have two seperate equations, one for NaOH and one for water, and then subtract?
Will i use 4.184 for specific heat?
