The reaction will come to an end if all the reactants are used up. The reaction's limiting reactant is reactant B.
Limiting Reactant: The limiting reactant is the one that is consumed first and sets a limit on the quantity of product(s) that can be obtained.
This reactant is the one that restricts the production of products throughout the reaction. The reaction will come to an end if all of the reactants are used up.
surplus reactant
This is the limiting reactant that is present in excess and reacts with it all. Oxygen in the surroundings, as an illustration.
When all of the reactant B has been utilized, the reaction ends.

Answer:
The molarity of the solution is: 2,167 M.
Explanation:
Molarity is a concentration measure that expresses the moles of solute per liter of solution. In this case it is calculated with the simple rule of three:
3,6 L solution ------- 7,8 moles of MgCl2
1 L solution -----------x= (1 L solution x 7,8 moles of MgCl2)/3,6 L solution
x=2,167 moles of MgCl2 ---> <em>The solution is 2, 167 M</em>
Combustion
It is an example of a simple chemical reaction. In a combustion reaction, oxygen reacts with another substance to produce carbon dioxide gas and water vapor.
Answer:
B. bromelain
Explanation:
Pineapple also contains a digestive enzyme called bromelain, which is a mixture of proteolytic enzymes and has been chemically known since 1876 (Taussig and Batkin, 1988).
