Explain how many grams of glucose need to be burned to heat a block of metal from 23 °C to 167 °C? The piece of metal has a density of 3.438 g mL-1, a specific heat of 0.476 J g-1 °C-1, also has dimensions of 2.2×2.63×1.17 cm. Mass of metal block(g)= Heat required (kj)= Mass of glucose
Account for the fact that H3C-Cl (dipole moment 1.94D) and H3C-F (dipole moment 1.82D) have almost identical dipole moments, even though fluorine is considerably more electronegative than chlorine.
Consider the Lewis Resonance structure for the chlorite ion. How many total structures can be drawn, and how many of those structures obey the octet rule?
Consider a glass of 171 mL of water at 29°C. Calculate the mass of ice at -15°C that must be added to cool the water to 10°C after thermal equilibrium is achieved.
Calculate the mass/volume percent [% (m/v)] of 0.278 g of potassium chloride in a 987.8 mL solution.
