Answer: the correct answer would be the last option, C6H12O6 and O2
Explanation:
Answer:
0.0011 M.
Explanation:
Molarity of a substance , is the number of moles present in a liter of solution .
M = n / V
M = molarity
V = volume of solution in liter ,
n = moles of solute ,
Moles is denoted by given mass divided by the molecular mass ,
Hence ,
n = w / m
n = moles ,
w = given mass ,
m = molecular mass .
From the question ,
w = given mass of KMnO₄ = 0.0908 g
and ,
V = 0.500 L
Since ,
we know ,
m = Molecular mass of KMnO₄ = 158 g/mol
using , the above formula to calculate the moles ,
n = w / m = 0.0908 g / 158 g/mol = 0.00057 mol
now , calculating the molarity as ,
M = n / V = 0.00057 mol / 0.500 L = 0.0011 M.
The answer should be C. I dont know know if you have misspellings or not
In a chemical change, the atoms in the reactants rearrange themselves and bond together differently to form one or more new products with different characteristics than the reactants. When a new substance is formed, the change is called a chemical change. A chemical reaction is a mechanism that takes place when two or more molecules interact to produce new products. A reaction between two atoms or ions or molecules may take place and a new bond is formed and no atom is destroyed or created, but reactants form a new substance.
True ^_^
Mass was conserved, because it was losing all shape, weight, and matter. It really has no mass.
