Explanation:
To solve this problem, follow these steps;
- Obtain a balanced equation of the reaction and familiarize with the reactants and products.
- Find the number of moles of the reacting species since they are the known matter in terms of quantity.
- From the number of moles, determine the limiting reactant.
- The limiting reactant is the one given in short supply.
- Such reactant determines the extent of the reaction.
- Compare the moles of this specie to that of the products using the balanced equation.
- Obtain the mole of the desired product and find the mass or desired quantity.
- simply work from the known specie to the unknown

We know that the molar mass of Al is 27 g/mol.
27 g Al* (1 mol Al/ 27 g Al)= 1 mol Al.
The final answer is 1 mol Al~
Answer:
Explanation:
Atomicity of an element is a measure of the total number of atoms present in a molecule. For example- O2 , O Similarly, an ozone molecule consists of 3 atoms of oxygen and has an atomicity of 3. The atomicity of ammonia is NH3.Ammonia is a compound of nitrogen and hydrogen with the formula NH3.
(Could very much be incorrect, it's just what I think it is.)
NaOH (aq) + HCl(aq) => NaCl(aq)+ H2O(l)
Na+(aq)+ OH - (aq) + H +(aq) +Cl - (aq) + Cl- (aq)
=> Na+(aq) + Cl - (aq) + H2O(l)
H+(aq) + OH-(aq) => H2O(l)
Arsenic
Arsenic has an atomic mass of 74.92, is a well known poison, and a metalloid.
