An exothermic reaction is a chemical reaction that releases energy by light or heat.
Answer: The mass of aluminium sample is 55.4 gram
Explanation:
As we know that,
where,
= mass of aluminium = ?
= mass of water = 300.0 g
= final temperature =
= temperature of aluminium =
= temperature of water =
= specific heat of aluminium =
= specific heat of water =
Now put all the given values in equation (1), we get
Therefore, the mass of aluminium sample is 55.4 gram
<h2>Answer:</h2><h3>Balanced equation:</h3>
2C4H10 + 8O2 → 8CO2 + 10H2O
<h3>Description:</h3>
There should be 8 molecules of oxygen which react with 2 molecules of butane to produce 8 molecules of carbon dioxide and 10 molecules of water.
