C) Step 1: a horizontal spinning effect is formed from wind shear
Step 2: warm rising air shifts the horizontal rotation to a vertical rotation
Step 3: the vertical rotation expands and extends
It is a combustion reaction because when methane burns with oxyzen it produces carbon dioxide,water and heat and light.
Hey There!:
2 C2H2 + 5 O2 = 4 CO2 + 2 H2O
2 moles C2H2 ----------- 5 moles O2
35.0 moles C2H2 ------- moles O2
moles O2 = 35.0 * 5 / 2
moles O2 = 87.5 moles
hope this helps!
This is a double replacement because both Copper and Sodium reacted with each other compounds , hence "double"
