Compounds are formed by bonding atoms of two or more different elements through chemical reaction. Atoms are bonded by losing or gaining electrons in ionic bonding and by sharing electrons in covalent bonding between two atoms participating in the bond formation. For example, one molecule of the compound water is formed by bonding two atoms of hydrogen and one atom of oxygen by sharing electrons between the atoms and forming covalent bonds. Therefore, compounds are created by losing, gaining or sharing electrons between other atoms.

(Answer) (D) By losing, gaining, or sharing electrons between other atoms.

What is the volume (in cubic inches) of 3.6 lb of titanium? The density of titanium is 4.51 g/cm3

SashulF [63]

Answer: 362,07 cm3
To answer this question you need to convert the lb into gram first. One lb equal to 453.592g, so: 3.6lb x 453.592gram/lb= 1632.9312gram.
Now we have mass(1632.9312g), density (4.51g/cm3). Volume is mass divided by density. The equation would be:

Volume= mass/density
Volume = 1632.9312gram / (4.51g/cm3)= 362,07 cm3

<h3>Explanation:</h3>

<u>Step 1: Define</u>

[Given] 2.16 moles SO₂

[Solve] grams (mass) SO₂

<u>Step 2: Identify Conversions</u>

[PT] Molar Mass of S - 32.07 g/mol

[PT] Molar Mass of O - 16.00 g/mol

Molar Mass of SO₂ - 32.07 + 2(16.00) = 64.07 g/mol

<u>Step 3: Convert</u>

[DA] Set up: $\displaystyle 2.16 \ mol \ SO_2(\frac{64.07 \ g \ SO_2}{1 \ mol \ SO_2})$
[DA] Multiply/Divide [Cancel out units]: $\displaystyle 138.391 \ g \ SO_2$

<u>Step 4: Check</u>

<em>Follow sig fig rules and round. We are given 3 sig figs.</em>

138.391 g SO₂ ≈ 138 g SO₂
