Noble gases have a FULL balance she’ll with 8 electrons. Because their balance she’ll is full they DONT need to borrow or gain electrons
fyi it’s actually:
Noble gases have a full valence shell with eight electrons. Because their valence shell is full they don’t need to borrow or gain electrons.
Answer:
Mornin'!
Explanation:
(Actually, it's the afternoon over where I am.)
Molar mass is the mass of each element multiplied by subscript, then added together.
So, we’ll do
C = 12g x 12 = 144 g
H = 1g x 22 = 22 g
O = 16g x 11 = 176 g
The total of all of these is the molar mass: 342 g in a mol
The amount of mols of each element in each compound is likely equal to its subscripts.
C = 12 mols
H = 22 mols
O = 11 mols
For the atoms, you’ll multiply each one of the above by Avogadro’s number
Avogadro’s Number: 6.02 x 10^23 atoms/mol
Answer:
Decrease temperature with increase in ammonium nitrate concentration.
Explanation:
The temperature changes when different masses of ammonium nitrate are dissolved in water because the ammonium nitrate takes energy from the surrounding water environment for the breaking of ionic bonds as a result the temperature of water decreases. When more concentration of ammonium nitrate is added to water, more decrease occur in temperature of water and the water becomes cold.
