Answer:
<u>Osmosis </u>is the process that describes water moving through a membrane.
I am not sure about the second question.
Explanation:
Answer:
Solar energy is energy from the sun converting it to thermal or electric energy. It is renewable resource meaning it will never die out. It is also called radiant energy.
Explanation:
Acids are substances that can donate H+ ions to bases. Since a hydrogen atom is a proton and one electron, technically an H+ ion is just a proton. So an acid is a "proton donor", and a base is a "proton acceptor". The reaction between an acid and base is essentially a proton transfer.
The relationship between acids and bases is more aggressive than the donor/acceptor terminology implies. Bases don't passively "accept" protons; they rip hydrogen ions from acids. Acids don't "donate" hydrogen ions; they surrender them.
Answer:
88.5 g/m is the molar mass for the gas
Explanation:
We need the Ideal Gases Law equation to solve this:
P . V = n . R . T
Pressure (P) = 10 Torr
We must convert to atm → 10 Torr / 760 Torr = 0.0131 atm
Volume (V) = 255 mL
We must convert to L → 255 mL / 1000 = 0.255 L
n = number of moles
moles = mass in g / molar mass
12.1 mg/ 1000 = 0.0121 g
T° = 25°C + 273K = 298K
R = 0.082 L.atm /mol.K
Let's replace the values
0.0131 atm . 0.255L = 0.0121 g / x . 0.082 L.atm /mol.K . 298K
(0.0131 atm . 0.255L) / (0.082 L.atm /mol.K . 298K) = 0.0121 g / x
1.367×10⁻⁴ /mol = 0.0121 g / x
x = 0.0121 g / 1.367×10⁻⁴ mol = 88.5 g/m
Answer:
a
Explanation:
Chemical then thermal because the carbon emissions produce heat
Then kinetic because there is energy transfer then electric because that's the finished result
