167g. Because the law of conservation of mass says that matter can not be created or destoryed, in a chemical reaction.
Answer:
H20is water andN20is nitrogen 4 oxide
Heat can be transferred from one place to another by conduction in solids, convection of fluids like liquids or gases, and radiation. A temperature difference in a system causes heat to move from higher to lower temperatures
when heat gained = heat lost
when AL is lost heat and water gain heat
∴ (M*C*ΔT)AL = (M*C*ΔT) water
when M(Al) is the mass of Al= 225g
C(Al) is the specific heat of Al = 0.9
ΔT(Al) = (125.5 - Tf)
and Mw is mass of water = 500g
Cw is the specific heat of water = 4.81
ΔT = (Tf - 22.5)
so by substitution:
∴225* 0.9 * ( 125.5 - Tf) = 500 * 4.81 * (Tf-22.5)
∴Tf = 30.5 °C
D is the answer. A, B,C are absurd. Doing a little word right there.
