How do you balance a chemical equation
1 answer:
There should be mass balance and the charge balance between the reactants and the products
Mass balance : total no of individual atoms of each type should be balanced before and after the reaction
Charge balance : Overall charge of the reactants should be balanced with the overall charge of the products
You can balance,
1)by just looking at it
2)by Algebraic method given above or
3)by the redox method
You need to know how to get the oxidation numbers in order to use the oxidation method

Answer:
C. Water will move from solution A to solution B because glucose is in higher concentration.
Explanation:
In osmosis, the molecules of solvent will pass through a semipermeable membrane from a less concentrated to a more concentrated solution.
Solution B is more concentrated, so the water will move from A to B.
A and D are wrong, because the size of the solute particles does not control the direction of osmosis.
B is wrong because water moves to the more concentrated solution.
