Answer: The atom count for each element on the reactant side of a balanced chemical equation is equal to the atom count for each element on the product side of the same equation
Explanation:
According to the law of conservation of mass, mass can neither be created nor be destroyed. Thus the mass of products formed must be equal to the mass of reactants taken.
In order to get the same mass on both sides, the atoms of each element must be balanced on both sides of the chemical equation.
Thus there are 4 atoms of hydrogen on reactant as well as product side.
Also there are 2 atoms of oxygen on reactant as well as product side.
Answer:
B
Explanation:
cause surface area of solute is not necessary for solution
Answer:- B. Solvent molecules surround solute ions.
Explanations:- When an ionic solute that has positive and negative ions is dissolved in a solvent like water then the solute ions are surrounded by the water molecules in a way so that the highly electron negative oxygen atom of water is towards the positively charged ion of the solute and less electron negative which is hydrogen atom that has partial positive charge, surrounds the negatively charged ion of the solute.
Due to these forces made by the solvent molecules, the solute is broken into the ions and get dissolved in solvent.
