Water (2150 gg ) is heated until it just begins to boil. If the water absorbs 5.91×105 JJ of heat in the process, what was the i

Serjik [45]

Answer:

Initial temperature of water was 34,3°C

Explanation:

The heat absorbed in the process (Q) can be written as:

Q = mcΔT

Where the heat is 5,91x10⁵J, m is mass of water (2150g), c is specific heat of water (4,184J/g°C). And ΔT is change in temperature (100°C - x). Replacing:

5,91x10⁵J = 2150g×4,184J/g°C×(100°C - x)

5,91x10⁵J = 899560J - 8995,6J/°Cx

-3,0856x10⁵J = - 8995,6J/°Cx

34,3°C = x

Thus, <em>initial temperature of water was 34,3°C</em>

I hope it helps!

Baking soda mixed with vinegar produces carbon dioxide and water. The best way to prove that no mass was lost during this reacti

lord [1]

Given what we know, we can confirm that the best way to prove that no mass was lost during the reaction would be to follow option C and determine the masses of all substances before and after the reaction.

<h3>Why is this the best method?</h3>

This method provides two sets of data in order to draw a comparison. The other option will either not produce comparable data, or do not take into account all of the elements being produced.

Therefore, by comparing the mass of baking soda and vinegar before the reaction to the mass of carbon dioxide and water after the reaction, we can analyze the differences if any, and confirm that no mass was lost during the reaction.
