Answer:
electron configuration
Explanation:
The arrangement of electrons in the atomic orbitals of an atom is called the electron configuration. Electron configurations can be determined using a periodic table.
Answer:
2.57 g of H₂
Solution:
The Balance Chemical Equation is as follow,
N₂ + 3 H₂ → 2 NH₃
According to Balance equation,
34.06 g (2 moles) NH₃ is produced by = 6.04 g (3 moles) of H₂
So,
14.51 g of NH₃ will be produced by = X g of H₂
Solving for X,
X = (14.51 g × 6.04 g) ÷ 34.06 g
X = 2.57 g of H₂
Answer:
the molar mass of propane (c3H8) is
12*3+1*8
=36+8=44
Answer:
Explanation:
The symbol of beryllium is Be. It is located in the second group on the periodic table.
Beryllium is a divalent cation with a charge of +2.
It is capable of losing 2 electrons in order to be like the noble gas He and this is a more stable configuration.
