Most transition metal form more than one cation but aluminum forms the Al3+ cation only.
Answer:
Answer is B.
Explanation:
Hydrogen bonds forms when hydrogen atom is attracted towards oxygen atom of other water. A proton is shared by two ion electrons pair in which oxygen atom is partially negatively charged while hydrogen atom is partially positively charged.
The balanced equation would be:
2HCl + Mg(HCO3)2 —> MgCl2 + 2CO2 + 2H2O
I believe the correct answer is A. All of the other choices except A is related or associated with chemical equilibrium and should follow Le Chatelier's Principle. We take in oxygen and it is one of the reactants for cellular respiration where one of the products is CO2 and is the one being released not O2.
