Balanced chemical equation:
2 C2H2 + 5 O2 = 4 CO2 + 2 H2O
2 moles C2H2 ---------------- 5 moles O2
moles C2H2 ------------------ 84 moles O2
moles C2H2 = 84 * 2 / 5
molesC2H2 = 168 / 5 => 33.6 moles of C2H2
Answer:
behaviors that are passed down genetically
Answer:
there would be different times because the sun and moon are in different places and one side would be sunny for a long time
Explanation:
Water also dissolves non-ionic substances.This is because C2H5OH has a polar Oh and the bond that the water molecules like to hang around. Many substances do not dissolve in water and that is because they are non-polar and do not interact well with water molecules. A common example is oil and water.
