What mass of carbon dioxide will be formed when a mixture containing 1.93 g of ethylene and 5.92g of oxygen is ignited?

C2H4 + 3O2 -> 2CO2 + 2H2O


Is the reaction rate dependent on the concentration of the excess reagent?

If a higher concentration means a higher rate of reaction because of more collisions, then does the reaction rate depend on the concentration of the excess reagent?

10g of Sb2S3 reacts with 7.3g of HCl. how much of the reactant in excess is left at the end?

Ive worked out the limiting reactant which is Sb2S3. Ive calculated moles of Sb2S3. Do I multiply moles of Sb2S3 by 6 to get moles of HCl used? How do you work the mass in excess from... more
