What is the connection between Archimedes and the Mass-Volume lab

Chemistry
1 answer:
Usimov [2.4K]3 years ago
4 0

Answer:

Explanation:

This question is not very clear, however, going by the key words in the question, Archimedes' principle shows a relationship between mass and volume.

Archemedes' principle states that when a body is fully or partially immersed in fluid, it is acted upon by an upward force which is equal to the weight of the fluid displaced by the body.

The volume displaced here can be determined using the formula

Density of liquid = mass displaced ÷ volume

Hence, volume = mass displaced ÷ density of liquid

What is the mass of an atom with 15 neutrons and 13 electrons ?
slava [35]
The mass would be 28. The mass of an atom equals the number of neutrons and protons added together. In this case, they do not say the protons. But we must use our inside knowledge to know that the number of protons equals the number of electrons. Thus, your number of protons would be 13

What is the net charge of the ionic compound calcium fluoride
yKpoI14uk [10]

Answer:

  • <em>The net charge of the ionic compound calcium fluoride is </em><u><em>zero (0).</em></u>

<em>Explanation:</em>

<em>Ionic compounds,</em> such as covalent ones, have zero net charge; this is, they are neutral.

Substances with net positive charge are cations and substances with net negative charge are anions.

The charges in the <em>ionic compound calcium flouride</em> are distributed in this way:

  • Compound formula: CaF₂

  • Calcium charge: Ca²⁺: this is, each calcium ion has a 2 positive charge

  • Fluoride charge: F⁻: each fluoride ion has a 1 negative charge.

  • Then, the <em>net charge</em> is: 1 × (2+) + 2 × (1-) = +2 - 2 = 0.

So, a two positve charge, from one calcium ion, is equal to two negative charges, from two fluoride tions, yielding a <u>zero net charge</u>.
