Gasoline is burned having the chemical reaction:
Gasoline + 02 --------------------> CO2 + H20
Since conversion of gasoline into carbondioxide(gas) and water(liquid) is the the chemical change.
Others are physical change.
So , according to above explanation.
E) gasoline is burned is the correct answer.
The answer to this question would be: alkaline earth metal
Alkali earth metal is the second column group of the periodic table. In this group, the element has 2 extra electrons in their outer cells. That is why most of this metal has 2+ charge.
Their neighbor is the alkali metal which was the first column of the periodic table. The name is similar so don't confused and mix them each other.
Answer:
538L of carbon dioxide will be produced
Explanation:
This is a classic example of combustion of an alkane.
If balanced equation is not given; this format can come in handy.
For any alkane of the type : CₙH₂ₙ₊₂ , it's combustion reaction will follow:
2CₙH₂ₙ₊₂ + (3n+1) O₂ → (2n)CO₂ + 2(n+1) H₂O
For ethane:
2C₂H₆(g) + 7O₂(g) → 4CO₂(g) + 6H₂O(l)
Here, 2 mole of ethane gives 4 moles of CO₂.
or, of ethane gives of CO₂.
Then, 269L of ethane will give:
=
= L
= 538 L
Therefore, 538L of carbon dioxide will be produced
