Answer:
A
Explanation:
bc u have to think about it
The reaction is an exothermic reaction and the temperature change is calculated using the formula below:
- Change in temperature = final temperature - initial temperature
<h3>What kind of heat change occurs when anhydrous copper(II) sulfate is dissolved in water?</h3>
When, anhydrous copper(II) sulfate is dissolved in water, heat is given off to the surroundings and the temperature of the solution formed is higher than the temperature of the water used in dissolving it.
This type of reaction is known as an exothermic reaction.
The temperature increase is calculated using the formula below:
- Change in temperature = final temperature - initial temperature
In conclusion, exothermic reactions result in increase in temperature of their surroundings.

Answer:
if it is hydroxide
Explanation:
when metal. and non-metal most the time reacts and the none metal is hydroxide u can easily say it Is base
Answer:
5.99 moles of
Explanation:
In this case, we can start with the <u>decomposition</u> of , so:
<u>(Reaction 1)</u>
The can react with carbon to produce :
<u>(Reaction 2)</u>
If we 8.99 mol of , we can calculate the moles of that we need. In reaction 2 we have a <u>molar ratio</u> of 1:2 (2 moles of will produce 1 mol of ):
With this value and using the <u>molar ratio</u> in reaction 1 (3 moles of are producing by each mol of ), so:
So, we will need 5.99 moles of to produce 8.99 mol of .
I hope it helps!
