This is an incomplete question, here is a complete question.
What is the maximum number of moles of calcium sulfate that can be theoretically produced when 2.58 moles calcium hydroxide react with excess of sulfuric acid.
Answer : The maximum number of moles of calcium sulfate produced will be, 2.58 moles.
Explanation : Given,
Moles of calcium hydroxide = 2.58 moles
The balanced chemical reaction will be:
![Ca(OH)_2+H_2SO_4\rightarrow CaSO_4+2H_2O](https://tex.z-dn.net/?f=Ca%28OH%29_2%2BH_2SO_4%5Crightarrow%20CaSO_4%2B2H_2O)
Now we have to determine the moles of calcium sulfate.
From the balanced chemical reaction we conclude that,
As, 1 mole of calcium hydroxide react to given 1 mole of calcium sulfate
So, 2.58 mole of calcium hydroxide react to given 2.58 mole of calcium sulfate
Thus, the maximum number of moles of calcium sulfate produced will be, 2.58 moles.
Answer:
A. Space Probes
A space probe is a robotic spacecraft that does not orbit Earth, but instead, explores further into outer space. A space probe may approach the Moon; travel through interplanetary space; flyby, orbit, or land on other planetary bodies; or enter interstellar space

Endothermic reaction
down
Explanation:
A chemical reaction that absorbs energy from the environment is known as an endothermic reaction. In such a system the surrounding becomes colder at the end of the changes. The temperature of the system after the reaction will go down.
- The enthalpy changes are the heat changes accompanying physical and chemical changes.
- In endothermic reaction, the enthalpy change is assigned a positive sign.
- This is because the heat energy level of the final state is higher than that of the initial state.
- The temperature of the water bath goes down as the reaction would cold to feel.
