Answer:
A. Their numbers of atoms
Explanation:
Yea this makes me happy I love talking about bonds Here is a explanation since there is no question.
In the ionic bond that creates sodium fluoride, for example, the element sodium loses one of its 11 electrons to balance the 9 electrons in Fluoride because the ionization energy of sodium (the charge required to lose an electron) is low.
Glad to help
Have a wonderful day
Answer:
0.92% NaCl
Explanation:
To find the weight percent (aka. mass percent), you need to use the following equation:
mass of solute (g)
Mass Percent = --------------------------------- x 100%
mass of solvent (g)
In this case, NaCl is the solute and water is the solvent. You can plug the given values into the equation and solve for the mass percent.
4.6 g NaCl
Mass Percent = ------------------------ x 100%
500 g H₂O
Mass Percent = 0.0092 x 100%
Mass Percent = 0.92%
Answer: Molarity of this solution is 0.88 M
Explanation:
Molarity : It is defined as the number of moles of solute present in one liter of solution.
Formula used :
where,
Given : 3.0 g of hydrogen peroxide is present in 100 g of solution.
n = moles of solute =
= volume of solution in ml=
Now put all the given values in the formula of molarity, we get
Thus molarity of this solution is 0.88 M
Answer:
Kw= = [H3O+][OH-] = [H+][OH-].
Explanation:
In chemistry, the term 'equilibrium'' is a period or time in which the rate at which the product is been produced or generated is equal to the quantity of the reactants reacting. In order way, we can say the equilibrium is when forward Reaction is equal to the backward Reactions.
The general equilibrium expression for the self-ionization of water is given below;
Kw = [H3O+][OH-] = [H+][OH-].
The kw is now equal to 1.001x10-14 at 25°C. Kw which is the equilibrium constant is also refer to as the dissociation constant of water.
