A positivey charged subatomic ion is a <em>proton</em> which is in the nucleus
A negitively charged subatomic ion is an electon which is found outside the nucleus in the electron cloud
A neutral subatomic ion is a <em>neutron </em>which is also in the nucleus
thermal contact
When heat flows from one object or substance to another it is in contact with, the objects or substances are said to be in thermal contact. The state where objects in thermal contact with each other reach the same temperature, no heat flows between them.
Answer:
the pressure (torr) of theH₂ gas is 736.2 torr
Explanation:
Given that
The H₂ gas produced in a chemical reaction is collected through water in a eudiometer; during this process, the gas collected contains some droplets of water vapor along with these gas.
So; the total pressure in the eudiometer = Pressure in the H₂ gas - Pressure of the water vapor
Where;
= total pressure in the eudiometer = 760.0 torr
= Pressure in the H₂ gas = ???
= Pressure in the water vapor = 23.8 torr
Now:
= +
- = + -
= - +
= (- 23.8 + 760) torr
= 736.2 torr
Thus; the pressure (torr) of theH₂ gas is 736.2 torr
Answer:
3.25 moles of sodium chloride to grams: 189.3545 grams
Explanation:
1 moles NaCl = 58.44277 gram
It's already balanced since there is an equal number of elements on each side!
