When 2.500 g of sulfur was burned completely in oxygen to form SO2(g), the temperature of a bomb calorimeter with the heat capacity 3.559kJ/oC/was raised from 22.00oC to 28.55oC. Calculate ΔHo (kJ) for the reaction per mole of SO2 formed.

Do polar molecules have ionic bonds?

Rank the following four acids in order of increasing bronsted acidity : h2f+ , ch3oh, (ch3)2oh+ , ch3sh2+

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.
