<span>Answer: yes, when calcium hydroxide powder is placed into a hydrochloric acid solution, aqueous calcium hydroxide and water are formed.
</span>
<span /><span /><span>
Explanation:
</span><span>1) Calcium hydroxide is a base whose chemical formula is: Ca(OH)₂</span>
<span /><span>
2) Hydrochloric acid is the acid with chemical formula HCl
</span><span>3) Acids and bases react in a double replacement reaction forming salt plus water: Acid + Base → salt + water
</span>

4) The specific chemical equation for these reactants is:
</span><span>Ca(OH)₂ (s) + 2HCl(aq) → CaCl₂ (aq) + 2H₂O(l)</span>
<span /><span>
</span><span>5) CaCl₂ is calcium chloride, a salt, and H₂O is water

Answer:
The answer is A
Explanation:
Because . . .
- A is correct because scientist make their statements by using their observations and tools to measure.
- B is incorrect people's opinions are not facts! Plus, opinions can be wrong.

- D is absolutely incorrect because guessing a "right" answer can be wrong. For example, if you were a scientist and you guessed a treatment for coronavirus, you will defiantly get fired because you don't have evidence or logic to back up your answer. In addition, if people used ur "treatment" the one you have guessed as the "right" answer, you can put people's lives in danger and they can possibly die. You will defiantly be responsible for it and be put into jail.

<h3>What is hydrocarbon made of?</h3>
Hydrocarbons, which are only composed of carbon and hydrogen, make up the majority of crude oil, refined petroleum hydrocarbons (including gasoline, diesel, kerosene, fuel oil, and lubricating oil), coal tar, creosote, dyestuff, and pyrolysis waste products.
