Question

Which statement best describes how alkali earth metals react with water?

A. Most alkali earth metals react with cold water.
B. All alkali earth metals do not react with any type of water.
C. All alkali earth metals react strongly with water at room temperature.
D. Most alkali earth metals react with hot water.

I got this wrong the first time so its not C. It's a little confusing so If someone could help that'd be great.

Here's where I'm supposed to get my answer: Alkali Earth Metals - The elements in Group 2 of the periodic table are named the alkali earth metals. An atom of an element in this family has two electrons in its valence shell and tends to form 2+ cations through chemical reactions. Beryllium (Be), which is at the top of the group, will not react with water. Magnesium (Mg), however, will react with hot water. The rest of the group naturally reacts with water at any temperature, hot or cold. Also, these elements are much harder than the alkali metals.

Answer 1

The right answer is:

*Most alkali earth metals react with hot water.

I took the test and got it right!

Step-by-step explanation:

Answer 2

Answer;

A. Most alkali earth metals react with cold water.

Explanation;

• Alkali metals react vigorously with water. Starting from sodium, they react explosively to water, as hydrogen gas is produced in the process. The reactivity even increases down the group.
• The alkali metals basically react with water to form metal hydroxide and hydrogen gas.
• All the alkaline earth metals except beryllium also react with water to form strongly alkaline hydroxides.
