I don’t know about 1 But number 2 is AB + xH2O = AB.xH2O
C. The action/reaction law states that a force is equal in both directions.
Answer:
1.4 g H₂O
Explanation:
In a reaction, the reactants are usually not present in exact <em>stoichiometric amounts</em>, that is, <em>in the proportions indicated by the balanced equation</em>. Frequently a large excess of one reactant is supplied to ensure that the more expensive reactant is completely converted to the desired product. Consequently, some reactant will be left over at the end of the reaction. T<em>he reactant used up first in a reaction</em> is called the <em>limiting reagent</em>, because <u>the maximum amount of product formed depends on how much of this reactant was originally present</u>. When this reactant is used up, no more product can be formed.
Answer:
3.52 moles are equal to 21.2 ×10²³ molecules
Explanation:
Given data:
Number of moles of oxygen fluoride = 3.52 mol
Number of molecules = ?
Solution:
The given problem will solve by using Avogadro number.
1 mole contain 6.022×10²³ molecules
3.52 mol ×6.022×10²³ molecules / 1 mol
21.2 ×10²³ molecules
Thus, 3.52 moles are equal to 21.2 ×10²³ molecules .
