2. Use the following chemical equation for the next problem: ZrSiO4 + 2Cl2 → ZrCl4 + SiO2 + O2
If 62.10g of ZrSiO4 and 52.23g of Cl2 are available according to the equation, which compound is the limiting reactant? Use mass of ZrCl4 as the product.

Imagine that you have produced several versions of lactase, each of which differs from normal lactase by a single amino acid. describe a test that could indirectly determine which of the versions significantly alters the three-dimensional shape of the lactase protein.

If you add 10ml of hot water to 10ml of cold water and the change in tempature 8°c calculate how much energy is gained by the cold water

Which process does not require the presence of a physical substance in order to transfer heat? air in the atmosphere is heated by the ground. this warm air then rises, and cooler air falls. this is an example of what type of process? how is conduction different from radiation?
