To balance a chemical equation, place coefficient as needed in front of the symbols or formulas of the elements. So the same number of each type of atom occurs in both reactants and products.
Steps to be followed are-
(1) Write down the chemical reaction in the form of word equation, keeping all the reactants on left hand side and keeping products on right hand side.
(2) Write all the symbol and formula of all reactants and products in word equation.
(3) Balance the whole equation by multiplying the symbols and formula by smallest possible figures.
Same number of each and every atom, of same type occurs in both reactants and products.
Once all the individual elements are balanced, then the total number of atoms of each element on the reactant and product side are compared once again after balancing. If there are no inequalities, the chemical equation is said to be balanced.

Answer:
it can hold up to 12 electrons.
explanation:
the p sub levels have 6 elements each, they each hold 2 electrons, so the entire p sub levels have 12 electrons.
Answer : The molality of solution is, 5.69 mole/L
Explanation :
The relation between the molarity, molality and the density of the solution is,
where,
d = density of solution = 1.25 g/mL
m = molality of solution = ?
M = molarity of solution = 4.57 M
= 98 g/mole
Now put all the given values in the above formula, we get
Therefore, the molality of solution is, 5.69 mole/L
However, the greatest threats to sea turtles aren't from natural predators; they are from humans. Accidental catch in commercial fisheries or entanglement in marine debris are serious threats to sea turtles, as well as destruction of beach habitat, harvesting or poaching for meat and eggs, and even boat strikes.
