~ A mole is a unit of 6*10^23.
~One mole of carbon atoms has a mass of exactly 12 g.
~ Because magnesium atoms each have twice the mass of carbon atoms ( 24Mg compared with 12C), one mole of magnesium has a mass of 24 g.
~ Rather, one mole of any element has a mass in grams that is equal to its relative atomic mass.

brainliest?
also, im in 7th, im in high school algebra already. (im in advanced stuff)
ty!
Answer: B: Your ears send a message through the nerves to the brain.
<u>Answer:</u> The law that illustrates this is Boyle's Law
<u>Explanation:</u>
- Boyle's law: This law states that pressure of the gas is inversely proportional to the volume of the gas at constant temperature and number of moles.
Mathematically,
(at constant temperature and number of moles)
- Charles' law: This law states that volume of the gas is directly proportional to the temperature of the gas at constant pressure and number of moles.
Mathematically,
(at constant pressure and number of moles)
- Avogadro's law: This law states that volume of the gas is directly proportional to the number of moles of the gas at constant pressure and temperature.
Mathematically,
(at constant pressure and temperature)
So, when the volume of the air in the gun decreases, the pressure is increased. The inverse relationship between the volume and pressure of the gas is very well illustrated by Boyle's Law.
Hence, the law that illustrates this is Boyle's Law
Answer:
1×
Explanation:
To solve this, you will need to do multiple steps.
Firstly, you will have to convert to pOH from pH, which is done by simply subtracting 14-10 to get a pOH of 4.
Then, use the following formula to calculate the [OH-} concentration:
[OH-]= 
When converted to Scientific Notation<u>,</u> you get a resulting answer of
<u>1×</u>
