The atom that is made up of two protons is He. The number of neutrons is also two. The number of electrons matters in the charge. So to make 10 electrons, we add 8 more. hence, 4/2 He 8-.

Milk has a density of 1.04 g/ml. If you have a volume of 510 ml, what is the mass in grams
Law Incorporation [45]

Density is defined as the ratio of mass and volume. The formula of density is:

density = \frac{mass}{volume}     -(1)

Density of milk = 1.04 g/mL   (given)

Volume of milk = 510 mL      (given)

Substituting the values in formula (1):

1.04 g/mL = \frac{mass}{510 mL}

mass= 1.04 g/mL \times 510 mL

mass = 530.4 g

Hence, the mass of the milk is 530.4 g.

This question is for science. which options describes the particles of water as liquid water actively boils to become steam?
-BARSIC- [3]

Answer:

The correct option is;

a. The particles will gain a large amount of kinetic energy

Explanation:

As the water temperature reaches 100°C, which is the boiling point for water at atmospheric pressure, the continued heating is then used to break up the strong inter molecular forces between molecules of the water  such that the individual molecules are free to move about and due to the high temperature, have gained considerable amount of kinetic energy for the to rise to appreciable height and to also spread.

The heat which converts water into steam is called latent heat as during the boiling phase, the temperature of the water remains constant.
