Answer:

dsf

Explanation:

It is known that density is the amount of mass present in per liter of a substance.

Mathematically,    Density = \frac{mass}{volume}

It is given that mass is 2.75 kg or 2750 g (as 1 kg = 1000 g) and volume is 250 cm^{3}.  

Therefore, calculate the density of substance as follows.

                    Density = \frac{mass}{volume}

                                 = \frac{2750 g}{250 cm^{3}}

                                 = 11 g/cm^{3}

Thus, we can conclude that density of given substance is 11 g/cm^{3} .

Sloan [31]

Answer:

[Top row] - Chemical bonds

[2nd Row L-R] - Force, Ionic, Covalent

[3rd Row L-R] - Atoms, Lost or Gained, Shared

[4th Row L-R] - More stable, Metal and Nonmetal, Nonmetal and Nonmetal

Explanation:

<u>Chemical bonds</u> are a<u> </u><u>force</u> that hold together <u>atoms</u> in a substance to make compounds <u>more stable.</u>

<u>Chemical bonds</u> include two kinds: <u>Ionic</u> and <u>Covalent.</u>

<u>Ionic</u> in which electrons are <u>lost or gained</u> where attraction is between a <u>Metal and Nonmetal.</u>

<u>Covalent</u> in which electrons are shared where attraction is between a <u>nonmetal and nonmetal</u>.

I have been able to fill the concept map using the correct terms or phrases. The concept map talks about chemical bonds. There are two types of chemical bonds; which ionic bond and covalent bond.
