Use the Gizmo to mix 200 g of copper at 100 °C with 1,000 g of water at 20 °C. How much heat energy (q) did the water gain?
Now solve for the specific heat (c) of copper:

Which statement justifies that hydrogen peroxide (h2o2) is a polar molecule? the o – h bond is nonpolar and the molecule is asymmetric. the o – h bond is nonpolar and the molecule is symmetric. the o – h bond is polar and the molecule is asymmetric. the o – h bond is polar and the molecule is symmetric.
