As is, the equation has:
Reactants:
2 K
2 O
2 H
Products:
1 K
1 O
1 H
So, we can add coefficients to balance the equation:
K2O + H2O = 2KOH
The coefficient means that there are 2 moles of KOH, and now the equation is balanced as there is 2 of everything on both sides.
Answer:
7 protons
Isotopes are atoms that have the same number of protons but different numbers of neutrons in the nucleus. You know that nitrogen-14 has 7 protons in the nucleus because it is an isotope of nitrogen, which has an atomic number equal to 7 .
The dilution factor of the unknown sample is 10. The dilution factor of a solution refers to the ratio of the final volume of the now diluted solution to the initial volume of the of the initial concentrated solution.
Mathematically;
The dilution factor is given by the formula;
Dilution factor = Final volume of the now diluted solution/ Initial volume of more concentrated solution
Final volume of the now diluted solution = 100.0 ml
Initial volume of more concentrated solution = 10.00 ml
Dilution factor = 100.0 ml/10.00 ml
Dilution factor = 10

I don't know exactly but you can try narrowing down your answers down to A or D but it might be D if the system is random if that even helps and makes sense-
