Answer:
When two atoms with different electronegativities are bonded together, a bond dipole exists. These are displayed with an arrow originating at the atom with the lowest electronegativity and pointing toward the atom with the highest electronegativity.
Partial charges will exist on each atom when a bond exists between two atoms with different electronegativities. Since the atom with a higher electronegativity will have a stronger ability to attract electron, it will have a partial negative charge. The atom with a lower electronegativity will have an equal and opposite positive charge. As the difference in electronegativity increases, the resulting magnitudes of the partial charges will increase.
Bond character is used to describe the severity of the electronegativity differences between the two tans involved in a bond. Bonds that have ionic character correspond to a larger difference in electronegativities and covalent bond character corresponds to a smaller difference.
For example, increasing the electronegativity of an atom A in the PhET simulation and decreasing the electronegativity of atom B will result in a bond that is more ionic in character.
1. Yes because the ocean takes in the carbon dioxide from the air. This causes more acid in the water, this makes it hard to make shells and skeletons for the seal life that need them.
2.No because it isn't harmful unless it builds up. But there is people who work to clean and limit the chances of build-up.
Hope this helps :)
Answer:
1.69 g Na₂O
General Formulas and Concepts:
<u>Chemistry - Atomic Structure</u>
- Reading a Periodic Table
- Using Dimensional Analysis
Explanation:
<u>Step 1: Define</u>
0.0273 mol Na₂O
<u>Step 2: Identify Conversions</u>
Molar Mass of Na - 22.99 g/mol
Molar Mass of O - 16.00 g/mol
Molar Mass of Na₂O - 2(22.99) + 16.00 = 61.98 g/mol
<u>Step 3: Convert</u>
<u />
= 1.69205 g Na₂O
<u>Step 4: Check</u>
<em>We are given 3 sig figs. Follow sig fig rules and round.</em>
1.69205 g Na₂O ≈ 1.69 g Na₂O
