1) k2O = 2K(1+) + O(2-)
This is, every molecule of K2O consists of three ions (2 of K 1+, and one of O 2-)
2) Caluclate the number of moles of K2O
- molar mass of K2O = 2*39 + 16 = 94 g/mol
- n = mass / molar-mass = 9.4g / 94 g/mol = 0.1 mol
3) Multiply by 3 to have the number of moles of ions: 3 *0.1 mol = 0.3 mol of ions.
4) Multiply by Avogadro's number to obtain the number of ions"
0.3 mol * 6.0*10^23 =1.8 * 10^23 ions.
Answer: 1.8*10^23 ions
The number of protons is equal to their atomic number ever time.
For example: Carbon always has 6 protons
And the number of neutrons depends on whether it is Carbon 12 or 13 or 14 etc.
Answer:
energetic particles
Explanation:
"Pioneer 10" was the first aircraft to complete a mission to<em> Jupiter.</em> It was launched on<em> March 2, 1972</em> and eventually became the first spacecraft to travel across the asteroid belt.
"Pioneer 11" was considered to be the <em>second spacecraft </em>to have studied the outer solar system after the launch of Pioneer 10. It focused on studying the <em>asteroid belt, solar winds, cosmic ray</em>s and the condition surrounding Saturn and Jupiter.
Jupiter has a <em>magnetosphere</em> that constantly ejects energetic particles. It produces a lethal dose of radiation that is harmful, especially to humans. This damaged both Pioneer 10 and 11. However, Pioneer 10 is said to have been able to communicate with Earth for 30 years despite receiving damages.
So, this explains the answer.
Answer:
solubility
Explanation:
solubility is a measure of how much a substance will dissolve in a solvent.
