True will end up being the answer
You are correct, but you needn't worry about the signs so much. Just remember that the negative sign is used to denote a loss of energy; since the water is hotter, it will be losing energy (-Q) and the iron will gain energy (Q). Now, we substitute the values:
-149.3 * 4.184 * (T - 95) = 412 * 0.44 * (T - 5)
Solving this equation for T,
T = 74.8 °C
True
Enzymes help the body in digestion and other bodily functions which involve chemicals.
If the equation is complete the products would be manganese chloride and oxygen gas would be given off.
