How many neutrons are in a nucleus of uranium-238?

Chemistry
1 answer:
LenaWriter [7]3 years ago
8 0

Answer:

146

Explanation:

The mass of uranium- 238  is  238  mass units. The total mass of an element is the sum of its protons and neutrons.  There are  92  protons in this isotope, and its mass is  238 , so that means that there are,  238 − 92 = 146  neutrons. Thus, as weird as it may seem, the answer must be D.

Individual solute particles are broken apart from the solid by these particles. * a Solution b Insoluble c Solvent d Compounds
Maru [420]

Answer:

Individual solute particles are broken apart from the solid by the;

c. Solvent

Explanation:

A solution is the homogeneous mixture that is made up of two or more substances formed by dissolving a substance which can be a solid, liquid or gas in another substance known as the solvent which normally the larger part of the fraction of the solution than the solute and can also be a solid, liquid or a gas

In a solution the solvent particles serves to brake of and disperser parts of a solid solute to form a more or less homogeneous mixture

Therefore, the solute particles are broken by the <u>solvent</u> particles in a solution

56.5 g of sodium nitrate is dissolved in water to make 627 g of solution . what is the percent sodium nitrate in the solution
Tamiku [17]

Answer:

9.01%

Explanation:

The following data were obtained from the question:

Mass of sodium nitrate, NaNO3 = 56.5g

Mass of solution = 627g

The percentage composition of sodium nitrate, NaNO3 in the solution can be obtained as follow:

Percentage composition of NaNO3 = Mass of NaNO3/mass of solution x 100

Percentage composition of NaNO3 = 56.5/627 x 100 = 9.01%

Therefore, the percentage composition of sodium nitrate, NaNO3 in the solution is 9.01%
