PLEASE HELP Q = m c T
Q = heat energy
m = mass
c = specific heat capacity
t = change in temperature
How much heat is required to raise the temperature of 67.0g of water from 25.7 C to 66.0 C? the specific heat of H2O is 4.184 J/g C) please show work

Need on both questionswill markbr />

Can someone me with questions 15 to 17 plz.

Achemist wants to extract copper metal from copper chloride solution. the chemist places 0.50 grams of aluminum foil in a solution containing 0.75 grams of copper (ii) chloride. a single replacement reaction takes place. (ii) chloride. a single replacement reaction takes place. which statement explains the maximum amount of copper that the chemist can extract using this reaction? a) approximately 0.36 grams, because copper (ii) chloride acts as a limiting reactant b) approximately 1.8 grams, because copper (ii) chloride acts as a limiting reactant c) approximately 0.36 grams, because aluminum acts as a limiting reactant d) approximately 1.8 grams, because aluminum acts as a limiting reactant
