They multiply the number moles by Avogadro's number
The two atoms shown in the equation are CALCIUM and oxygen.
<span>You start off with a neutral calcium atom with a shell of two electrons, a shell of 8 around that, a shell of 8 around that, and a shell containing 2...with no charge. </span>
<span>20 protons + 20 electrons. </span>
<span>You also have an oxygen atom with a shell of 2, and a shell of 6...with no charge. </span>
<span>8 protons + 8 electrons. </span>
<span>Each ionizes to form a calcium ion with 2 electrons removed (from the outer shell), leaving a +2 charge (20 protons, 18 electrons)... </span>
<span>and an oxygen ion with 2 electrons added (to the outer shell), leaving a -2 charge (8 protons, 10 electrons). </span>
<span>Their electrostatic attraction causes them to come together to form an ionic compound of CaO in a crystal lattice.</span>
Answer:
183.3 Km.
Explanation:
- The jet airplane reaches 846 Km in an hour (60.0 min).
- The question is what the distance the airplane covers in 13.0 min.
<em>Using cross multiplication:</em>
846 Km → 60.0 min
??? Km → 13.0 min
∴ The distance that the airplane covers in 13.0 min = (846 Km) (13.0 min) / (60.0 min) = 183.3 Km.
Need more context maybe put a picture or explain a little more
I'm not sure, however if you put sugar in water then the sugar particles speed up due to the fact that they dissolve in the water. Hope this helped! : D
