In each case, identify the element in question: (a) the mass number of an atom is 234 and the atom has 60.0% more neutrons than protons (b) an ion with a 2+ charge has 10.0% more protons than electrons (c) an ion with a mass number of 110 and a 2+ charge has 25.0% more neutrons than electrons

Asample of ammonia reacts with oxygen as shown. 4nh3(g) + 5o2(g) 4no(g) + 6h2o(g) what is the limiting reactant if 4.0 g of nh3 react with 8.0 g of oxygen? o2 because it produces only 0.20 mol of no. nh3 because it produces only 0.20 mol of no. o2 because it produces two times less no than nh3. nh3 because it produces three times more no than o2.

How many grams of co(g) are there in 74.5 ml of the gas at 0.933 atm and 30o c?

What does a complete balanced chemical equation include? a. exothermic coefficients b. endothermic coefficients c. valence electrons d. molar coefficients
