HOPE THIS HELPS! have a good day
Ca as a limiting reactant
<h3>Further explanation</h3>
Given
8 g Calcium
50 g HCl
<h3>Required</h3>
Limiting reactant
Solution
Reaction
Ca + 2HCl → CaCl₂ + H₂
mol Ca (Ar = 40 g/mol) :
= mass : Ar
= 8 g : 40 g/mol
= 0.2
mol HCl (MW= 36.5 g/mol) :
= mass : MW
= 50 g : 36.5 g/mol
= 1.37
Mol : coefficient reactants :
Ca = 0.2/1 = 0.2
HCl = 1.37/2 = 0.685
Ca as a limiting reactant(smaller ratio)
Answer:
3.1695 moles
Explanation:
Moles × grams/1 mole = x amount of grams
Grams: 1 mole/grams
the answer is B because I jus did that
Fluorine is the most active chemical element, reacting with virtually every element. It even reacts with the noble gases at high temperatures and pressures. The noble gases, or Group 18 (VIIIA), also known as the inert gases, generally do not react with other elements.
