Answer:

They are all alkali earth metals.

Explanation:

Their valence shell each has 2 electrons. Also, they are all shiny, silvery-white, somewhat reactive metals at standard temperature and pressure. They form alkaline solutions, hydroxides, when reacting with water and their oxides are found in the earth’s crust.

xxTIMURxx [149]

<u>Answer:</u> The chemical reaction is given below.

<u>Explanation:</u>

A fuel cell is defined as the electrochemical cell which converts the chemical energy of a fuel (often used hydrogen) and an oxidizing agent (often used oxygen) into electrical energy via a pair of redox reactions.

The reactions which occur in hydrogen-oxygen fuel cell are:

At cathode:  H_2+2OH^-\rightarrow 2H_2O+2e^-

At anode:  \frac{1}{2}O_2+H_2O+2e^-\rightarrow 2OH^-

Net reaction:  H_2+\frac{1}{2}O_2\rightarrow H_2O

Thus, the chemical reaction is given above.

g Which ONE of the following ionic compounds is insoluble in water? A) MgCO3 B) Li2CO3 C) NH4Br D) K3PO4 E) Pb(NO3)2
navik [9.2K]

Answer:

A) MgCO₃ is insoluble

Explanation:

Based on the rules of solubility:

All nitrates are soluble. That means Pb(NO₃)₂ is soluble.

All ammonium ions are soluble. NH₄Br is soluble.

All phosphate are insoluble except when combined with group I ions (Li, Na, K...) K₃PO₄ is soluble.

Also, all carbonates are insoluble except when combined with group I ions. That means Li₂CO₃ is soluble and:

<h3>A) MgCO₃ is insoluble</h3>
