Ammonia reacts with O2 to form either NO or NO2 according to the unbalanced equations shown below: NH3 + O2 → NO + H2O NH3 + O2 → NO2 + H2O In an experiment, 10 mol NH3 and 15.1 mol O2 are intially placed in a closed flask. After the reaction all the NH3 has reacted and 2.4 mol O2 remain. Calculate the number of moles of NO in the flask after reaction. Round your answer to two significant figures.

Fill in the coefficients that will balance the following reaction: a0cr2(so4)3 + a1agno3 -> a2cr(no3)3 + a3ag2so4

Plzz a sample of table sugar (sucrose, c12h22o11) has a mass of 7.801 g. ● a) calculate the number of moles of c12h22o11 in the sample b) calculate the number of moles of each element in c12h22o11 (number of moles of c, number of moles of h & number of moles of o) in the sample. (use your answer from part a as your starting point.) show your work and highlight your final answer. calculate the number of atoms of each element in c12h22o11 (number of atoms of c, number of atoms of h & number of atoms of o) in the sample. (use your answers from part b as your starting for each element.) show your work and highlight your final answer.
