Answer:
Explanation:
To calculate the initial temperature of the water:
where,
q = heat absorbed =
= specific heat of water =
m = mass of water = 2230 g
= final temperature of water =
= initial temperature of metal = ?
Now put all the given values in the above formula, we get:
Thus, the initial temperature of the water is
Answer:
The product is significantly impure
Explanation:
In order to test for the purity of a specific sample that was synthesized, the melting point of a compound is measured. Basically speaking, the melting point identifies how pure a compound is. There are several cases that are worth noting:
- if the measured melting point is significantly lower than theoretical, e. g., lower by 3 or more degrees, we conclude that our compound contains a substantial amount of impurities;
- wide range in the melting point indicates impurities, unless it agrees with the theoretical range.
Since our compound is even 10 degrees Celsius lower than expected, it indicates that the compound is significantly impure.
