number of hydrogen atoms present
Answer:
Explanation:
The balanced chemical reaction equation is;
2AgNO3(aq) + Cu(s) -> 2Ag(s) + Cu(NO3)2(aq)
When we balance chemical reaction equations, we ensure that the number of atoms of each element on the left hand side of the reaction equation is exactly the same number of atoms of each element on the right hand side of the reaction equation.
Let us consider this reaction;
There are two atoms of Ag on both sides of the reaction equation
There are six atoms of O on both sides of the reaction equation
There are 2 atoms of N on both sides of the reaction equation
There is one atom of Cu on both sides of the reaction equation.
Hence, the reaction equation is balanced.
The answer would be B ur looking for the total reaction and the time that it takes for it I be produced Wich would be 6.0
Answer: Option (d) is the correct answer.
Explanation:
A solute is defined as a substance which is present in small quantity into a solvent. Whereas a solvent is defined as the substance present in large amount as compared to a solute into a solution.
Therefore, always a solute tends to dissolve in solvent and never ever a solvent dissolves in a solute.
It is true that solutions can be made of liquids and solids, liquids and liquids, or gases and liquids. As a solution is a physical combination of two or more same or different states of matter.
Thus, we can conclude that out of the given options in a solution, the solvent is dissolved into the solute, this statement is incorrect.
