Answer:
physical change
Explanation:
i got the same question sorry for the late response but that's the answer good luck
It depends on how many electrons are already in the outer shell.
If it is a large amount (if it is almost to the maximum), then it will want to borrow from another atom.
But if it is close to empty then it will want to give away so it will go back to the inner ring with will be full.
Hope this helps, good luck!
Answer:
H₂ gas
Explanation:
The reaction between nitrogen gas and hydrogen gas forms ammonia (the Haber-Bosch process):
N₂ + 3H₂ ⇒ 2NH₃
The excess reactant can be found by comparing the moles of nitrogen and hydrogen. The molar mass of N₂ is 28.00 g/mol and the molar mass of H₂ is 2.02 g/mol.
(100 kg N₂)(1000g/kg)(mol/28.00g) = 3570 mol
(100 kg H₂)(1000g/kg)(mol/2.02g) = 49500 mol
The molar ratio between the reactant N₂ and H₂ is 1N₂:3H₂. The moles of nitrogen required to react with H₂ is:
(49500 mol H₂)(1N₂ / 3H₂) = 16500 mol
The amount of nitrogen required is more than what is available, so nitrogen is the limiting reagent and hydrogen is the excess reagent.
C the answer is cesium, study's show that it has the lowest ionization out of all elements. Hope this helped!
Answer:
FALSE
nuetrons do indeed have no charge, however they are nearly 2000 more times massive than electrons.
