Chemistry stoichiometry help plss !!! For EACH question, use dimensional analysis, mole ratios, units and labels. Round your answer to the same number of digits given in the problem. Show all your work.
Use this balanced equation for the four questions below:
C2H4 (g) + 3O2 (g) → 2CO2 (g) + 2H2O (g)

1. When 67.4 g of O2 are reacted, how many grams of carbon dioxide are produced?

2. How many grams of ethene (C2H4) are needed to produce 47.8 g of water?

PLS SHOW WORK THANKS!!

explanation:

venn diagram is pictorial representation with of circles showing the relation between two finite sets or things. the intersection part of two circles conveys the relation present in between those sets or things.

here in the venn diagram of sand and salt two circles represent sand and salt. but the area falling under the intersection of these circle represents the mixture of sand and salt.

so, in a venn diagram the mixture will be placed in a middle that is in between the intersection of two circles.

a boiling water reactor does not boil the water. a pressurized water reactor boils the water faster. a pressurized water reactor is heated directly by the core. a pressurized water reactor does not use fission.
