A simple solar energy heater is a glass-topped box containing rocks. Sunlight heats the rocks during the day, and air blown by night to heat the house. The box contains 7.5 x 10^4 g rocks, whose specific heat is 0.49 Jlg°C. How much additional heat can the rocks store when they warm from a night time of 18°C to a daytime temperature of 43°C? *

Which is true about the rate of consumption of hydrogen peroxide and the
rate of production of oxygen? Refer to the following table. *
Time (seconds)
[H2O2], mM
[02], mM
2
0.925
0.037
30
0.312
0.344
Rate of consumption of H202 = Rate of consumption of 02
Rate of consumption of H202 = 0.5 x Rate of consumption of 02
O Rate of consumption of H202 = 2 x Rate of consumption of 02
O Rate of consumption of H202 = (Rate of consumption of 02)2
