2 Assuming you start with 1 g of benzaldehyde work out how much malononitrile (NCCH2CN) you would need for the reaction. (7 marks) (Assume 1 mole of
benzaldehyde requires 1 mole of malononitrile for the reaction). Work out the mass of
tyrphostin you would get assuming a 100% yield for the reaction (3 marks).

How much would the freezing point of water decrease if 4 mol of sugar were added to 1 kg of water(k=1.86 c/mol/kg for water and i=1 for sugar

How does the presence of oxygen affect the chemical pathways used to extract energy from glucose?

Cryolite, na3alf6(s), an ore used in the production of aluminum, can be synthesized using aluminum oxide. start this question by first balance the chemical equation.1.) balance the equation: - alo3(s)+naoh(l)+hf(> na3alf6+h2o(g). 2.) if 17.5 kilograms of al2o3(s), 51.4 kilograms of naoh(l), and 51.4 kilograms of hf(g) react completely, how many kilograms of cryolite will be produced? 3.)which reactants will be in excess, (al2o3, naoh, or hf) 4.)what is the total mass of the excess reactants left over after the reaction is complete in kg?
