Question

Use the interactive to determine the number of H,0 molecules that form from reaction of 4 molecules of H, and 5 molecules of number of H, O molecules = molecules How many O, molecules are left over after the reaction? leftover 0, molecules = molecules

Answer 1

Balanced reaction for formation of tho from Hy and O₂ - 2H₂ + O2 240 (for such questions, balanced reaction, Given molecules of H₂ = 4 is required) molecules Given Moleculis oj 0,= 5 molecules from stoichiometic coefficients of above balanced chemical equation 2 molecules of it react with I molecule of O₂ to form 2 molecules of to I molecule of the will seact with I molecule of O to form I molecule of ho 4 molecules of Hy will react with 4 molecule of O₂ to form 1xu molecules of 40 Molecules of H2O formed = 1x 4 = 4 molecules O molecules reacted = 4 = 2 molecules but given 5 motuules of ₂ Number of molecules of O₂ left after reaction = 5-2=3 molecules 2
