Someone please help i'm so lost A commemorative Dave & Busters game token is composed of 98% copper, 0.50% tin, and 1.5 % zinc. Assume that mass of game token = 3.24 g

a) How much mass of copper, tin and zinc is there in the coin?

b) How many atoms of each do you have?

At 20°c, a sample of h2o liquid and a sample of co2 gas each have the same average kinetic energy. why is one a liquid and the other a gas at this temperature?

Ajet plane is speeding down the runway during takeoff. air resistance is not negligible. identify the forces on the jet.

Amines are good nucleophiles, even though they are neutral molecules. how would the rate of an sn2 reaction between an amine and an alkyl halide be affected if the polarity of the solvent is increased? amines are good nucleophiles, even though they are neutral molecules. how would the rate of an reaction between an amine and an alkyl halide be affected if the polarity of the solvent is increased? because both reactants in the rate-limiting step are neutral, the reaction will be faster if the polarity of the solvent is increased. because both reactants in the rate-limiting step are neutral, the reaction will be slower if the polarity of the solvent is increased. because both reactants in the rate-limiting step are neutral, the reaction will occur at the same rate if the polarity of the solvent is increased. request answer
