serg [7]3 years ago
4 0
In potassium sulfate (K₂SO₄):
1) potassium has oxidation number +1, because it is metal in first group of Periodic table of elements.
2) sulfur has oxidation number +6.
3) oxygen has oxidation number -2, because it gain electrons from potassium and sulfur.
Compound has neutral charge: +1· 2 + 6 + (-2) · 4 = 0.

Which bag held the most vibrant beads?
Zolol [24]

Answer:

  • <u><em>The bag with no sunscreen held the most vibrant beads.</em></u>

Explanation:

<em>SPF</em> is the Sun Protection Factor. It indicates how long a person can stay out in the sun before his skin start burning. It is a factor that is multiplied by 15 minutes. SPF 30 means 30 times 15 = 450 minutes. SPF 70 means 70 times 15 = 1,050 minutes.

Thus, the bag covered in <em>SPF 30</em> <em>sunscreen</em> will raise its temperature faster than the bag covered in <em>SPF 70 </em>sunscreen. And the bag with <em>no sunscreen </em>will raise its temperature faster than the other two.

The higher the temperature the more vibrant the particles that consititute the substances, thus, you conclude that the bag that held the most vibrant beads is the bag with no sunscreen.

Remember that the temperature is a measure of the kinetic energy:. The relation is: the higher the temperature the higher the kinetic energy.

Therefore, the more the particles vibrate, the higher the kinetic energy and the higher the temperature.

How many o atoms are present in 1.04 mol of mgso4??
HACTEHA [7]
To figure this out, you need to figure out how many molecules of mgso4 you have.
If you have 1.04 moles of MgSO4, you have that many moles times avogadro's number (6.022*10^23 molecules/mole).
1.04 moles MgSO4 * (6.022*10^23 molecules MgSO4)/1 mole MgSO4 =
6.263 *10^23 molecules MgSO4
Next, there are 4 oxygen atoms per molecule of MgSO4, so we multiply the number of molecules of MgSO4 by 4 to get the number of oxygen atoms.
6.263 *10^23 molecules MgSO4 * (4 oxygen atoms/1 MgSO4 molecule) = 2.51 * 10^24 oxygen atoms in 1.04 moles of MgSO4
