Problem: 0.1156 g CxHyNz reacts with oxygen, O2, to give 0.1638 g CO2, 0.1676 g H2O, and N2. Find the empirical formula of the organic compound.

CxHyNz + O2 → CO2 + H2O + N2

To determine the empirical formula you should know how much carbon, hydrogen, & nitrogen are each present in the sample. Follow the steps: Use dimensional analyses here.

1. Determine how much C is in CO2 then convert to mole.

2. Determine how much H is in H2O then convert to mole.

3. How do you think you can determine the amount of oxygen?

4. How do you think you can determine the amount of nitrogen?

In 1901, thomas edison invented the nickel-iron battery. the following reaction takes place in the battery. fe(s) + 2 nio(oh)(s) + 2 h2o(l) fe(oh)2(s) + 2 ni(oh)2(aq) how many mole of fe(oh)2, is produced when 5.35 mol fe and 7.65 mol nio(oh) react?

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
