Question

1. Balance the reaction: CsH18 + O2 + H2O + CO2 2. How many atoms of oxygen are in 1.000 mole of N20? How many protons are in 1.000 gram of elemental hydrogen? 4. If 0.042 moles of N2 reacts with 0.068 moles of O2 to make NO2, which one will be the limiting reagent? 5. Acids donate/accept protons and bases donate/accept protons.

Answer 1

- 17 Im balurred churrical reaction is- 2 (8418 + 25 02 - 16co2 & 18 H20 2 more ahom. of No contaans, more of origen As substanie per Aragadres Luw, one more of any senkins 6.022 x 1023 atoms, morcents or ions- I more who contains a 6.022x10 23 ahams of any gen. 33 - m abonic mass of elemental is a more of it arom contains = 1 gen of hydrogen more = 1 gm = 8:022 x 1023 atoms of H. As 1 Hydrogen contains = 1 proton 1 gm Hydrogen (elemental) contains = 6.022 x 1023 protons. Ime u

chemical reason is- The balanced N2 +202 9 2 Non moles of mole of N2 = o2 = 0.042 0.068 more mole from with balanned 2 more chanical equation & mole of de to prochne 2 more na reuts of No2 . 0.062 mok No requires = 0.042x2 02 = 0.084 moles of O2 & mores of or are ness. [ Limiting reactant - on vaygen is Lissong renserite & Aards donate profons and buses accept profons .
