hi guys i need help in these questions
When the following equation is balanced, the coefficient of H3P04 is Question 2 What is the maximum amount in moles of S05 that can be produced by the reaction of 6. 3 mol of S with 3. 1 mol of 02 via the equation below? (Note - this equation may need balancing). Question 3 In a quantitative analysis study, 2. 984 grams of a hydrocarbon (containing carbon and hydrogen only) yielded 8. 735 g of C02 and 5. 365 g of H20 in a combustion analysis apparatus. Determine the empirical formula of the compound, and hence select the appropriate molecular formula. Question 4 There are hydrogen atoms in 25 molecules of C4H4S2. Question 5 Magnesium bums in air with a dazzling brilliance to produce magnesium oxide: How many moles of 02 are consumed when 0. 770 moles of magnesium bums?
