How many grams of carbon dioxide would be formed if 38.9 g C2H2 reacted completely with oxygen
raketka [301]
2C₂H₂ + 5O₂ = 4CO₂ + 2H₂O

m(CO₂)/{4M(CO₂)} = m(C₂H₂)/{2M(C₂H₂)}

m(CO₂)=2M(CO₂)m(C₂H₂)/M(C₂H₂)

m(CO₂)=2*44g/mol*38.9g/26g/mol = 131.7 g

131.7 grams of carbon dioxide would be formed

CH2 - CH2 - CH3<br> |<br> CH3 - CH2 - CH - CH2 - CH = CH2
lianna [129]
The name of that product is 1-nonene.

The sufix ene is because it is an alkene, which comes from the fact that it has a double bond.

The prefix none is because it has 9 carbon.

And the use of number 1 is because the double bond is in the carbon number 1.

Name the following base: NaOH
soldier1979 [14.2K]

Answer:

Arrhenius Base

Explanation:

"NaOH is an Arrhenius base because it dissociates in water to give the hydroxide (OH-) and sodium (Na+) ions. An Arrhenius acid is therefore any substance that ionizes when it dissolves in water to give the H+, or hydrogen, ion. ... Acids provide the H+ ion; bases provide the OH- ion; and these ions combine to form water."
