(4,-3) lol if it's helpful ur welcome
Answer:
1
Step-by-step explanation:
Add one on both sides, combine like terms and solve.
Let five moles of oxygen are required to react with 2 moles of acetylene. So, doing a rule of three, we are going to obtain :
5 moles of Oxygen => 2 moles of C2H2
? O2 => 1 mole of C2H2
1.0 mole C2H2×(5 moles O2/2 moles of C2H2) = 2.5 moles of O2
So, the answer is <em><u>2</u></em><em><u>.</u></em><em><u>5</u></em><em><u> </u></em><em><u>m</u></em><em><u>o</u></em><em><u>l</u></em><em><u>e</u></em><em><u>s</u></em><em><u> </u></em><em><u>o</u></em><em><u>f</u></em><em><u> </u></em><em><u>o</u></em><em><u>x</u></em><em><u>y</u></em><em><u>g</u></em><em><u>e</u></em><em><u>n</u></em> are required to react with 1 mole of acetylene.
Because none of those are the right answer. you are given units in feet in the diagram. but are told 6 inches are lost in 4 hours. so you multiply length width and height keeping the feet then subtract .5 ft. the equation should look like V=(12×7×8)-.5
Answer:15h
Step-by-step explanation: because 8m+7m = 15h and the side the H is on is way bigger than the other sides so thats how you know your supposed to add.
