Calculate the temperature change in the water upon complete melting of the ice. Hint: Determine how much heat is absorbed by the melting ice and then use q =mC Delta T to calculate the temperature change of the 304 g of water.
What is the number of moles of atoms of oxygen contained in 49 grams of sulfuric acid, H2SO4?
A compound of forumula C14H12 gave a positive Baeyer test and burned with a yellow, sooty flame. Treatment with ozone followed by hydrolysis in the presence of zinc gave formaldehyde as one of the products.
