Balance. The fluid in your ears uses pressure to know what orientation your head is in.
Just LiOH, i also think Li2O + H2O = LiOH
Answer:
in contact
Explanation:
Fields allow some objects to exert force on each other even when they are not contact with one another.
The region of space where the effect of a force is felt is know as a field.
- Field forces for provides a non-contact means of exerting forces.
- They objects do not have to be in contact before the force is felt.
- An example is the gravitational force field.
Atomic weight of P = 31 g/mol
Molecular weight of P4 = 31*4 = 124 g/mol
You have 31 g of P4, so we can find how many moles of P4 you have:
31 g P4 divided by 124 g/mol P4 = 0.25 moles.
Now we have to multiply the number of moles (0.25) with Avogadros number:
0.25 mol * 6.022 x 10²³ molecules/mol = 1.5055 x 10²³ molecules of P4
P4 consists of four P, and each P has 15 neutrons (because it is number 15 in the periodic table)
1.5055 * 10²³ * 4 * 15 = 9.033 x 10^24
