yes
Explanation:
protons and neutrons are parts of elements
<h2>The grams of the excess reactant that are left at the end of reaction is</h2><h2>= 1.2014 grams</h2>
<h3>calculation</h3>
find the moles of each reactant
moles = mass/molar mass
molar mass of Ga= 69.7 g/mol
molar mass of As= 74.9 g/mol
mole of Ga = 4 g÷69.7 g/mol=0.05739 moles
moles of As=5.50 g÷74.9 g/mol =0.07343 moles
0.05739 moles of Ga reacted completely with 0.05739 moles of As therefore As was in excess
Therefore the moles of As that did not react = 0.07343 - 0.05739=0.01604 moles
mass that did not react = moles that was left x molar mass of As
that is; 0.01604 x 74.9=1.2014 grams
A catalyst is a compound that accelerates a chemical reaction without getting used up in the process.
Un catalizador es un compuesto que acelera una reacción química sin ser agotado en el proceso.
