Answer:
Ca (s) + 2H₂O (l) → Ca(OH)₂ (aq) + H₂ (g)
Explanation:
When solid calcium reacts with water, it produces the correspondent hydroxid and hydrogen gas.
The hydroxid which is produced, is the calcium hydroxid which is a strong base, that's why you talk about a highly alkaline solution.
Ca (s) + 2H₂O (l) → Ca(OH)₂ (aq) + H₂ (g)
Calcium hydroxide is a strong base, that dissociates in water, as this:
Ca(OH)₂ → Ca²⁺ (aq) + 2OH⁻ (aq)
It's a basic solution, is providing hydroxyl ions to the medium
Answer: There are two questions I could think of that weren't already on this list.
1) When did the genetic diversity of koalas decrease?
2) What kind of DNA does a koala have?
Answer:
Image A
Explanation:
The hemisphere experiences summer when it is tilted towards the sun. Image a has the northern hemisphere tilted towards the sun.
That is a true statement but you have to ask your teachet
