When all coefficients are multiplied by a single factor, The following actions are allowed while balancing a chemical equation: adding coefficients in front of reactant and product formulations.
<h3>How can chemical equations maintain balance?</h3>
Equal numbers and types of each atom appear on both sides of balanced chemical equations . Coefficients in a balanced equation must be the simplest whole number ratio. Chemical processes always retain mass.
<h3>What is a simple chemical equation?</h3>
A chemical equation is a symbol- and formula-based symbolic representation of a chemical reaction, with the reactant entities supplied on the left side and the product entities given on the right.

Answer:
cloths/sponges can harbor harmful pathogens and spread germs if not cleaned frequently. A damp, smelly dish cloth/sponge is telling you germs are multiplying!

Answer:
Atoms of sulfur = 9.60⋅g32.06⋅g⋅mol−1×6.022×1023⋅mol−1
Explanation:
because the units all cancel out, the answer is clearly a number, ≅2×1023 as required.
Answer:
67.5% ≅ 67.6%
Explanation:
Given data:
Mass of water = 17.0 g
Mass of oxygen produced (actual yield)= 10.2 g
Percent yield of oxygen = ?
Solution:
Chemical equation:
2H₂O → 2H₂ + O₂
Number of moles of water:
Number of moles = mass/ molar mass
Number of moles = 17.0 g/ 18.016 g/mol
Number of moles = 0.944 mol
Now we will compare the moles of oxygen with water to know the theoretical yield of oxygen.
H₂O : O₂
2 : 1
0.944 : 1/2×0.944 = 0.472 mol
Mass of oxygen:
Mass = number of moles× molar mass
Mass = 0.472 mol × 32 g/mol
Mass = 15.104 g
Percent yield:
Percent yield = [Actual yield / theoretical yield] × 100
Percent yield = [ 10.2 g/ 15.104 g] × 100
Percent yield = 0.675 × 100
Percent yield = 67.5%
