Answer:
1.2044 × 10^24 oxygen atoms
Explanation:
To convert from moles to atoms, simply multiply the number of moles by Avogadro's number, 6.022 × 10^23
2 × 6.022 × 10^23
=1.2044 × 10^24
Answer:
1.28 g
Explanation:
Mass of anhydrous compound/molar mass of anhydrous compound = mass of hydrated compound/ molar mass of hydrated compound
Mass of anhydrous compound = ?
Mass of hydrated compound = 2g
Molar mass of anhydrous compound= 160 g/mol
Molar mass of hydrated compound = 250 g/mol
x/160 = 2/250
250x = 2 ×160
x= 2 × 160/250
x= 1.28 g
C. losing one electron
Explanation:
It is because the potassium atom electronic configuration is 2,8,8,1 where by if it loses one electron it becomes stable
Some offspring may be tall, some may be short, and some may be medium medium sized.
The third shell has 3 subshells: the subshell, which has 1 orbital with 2 electrons, the subshell, which has 3 orbitals with 6 electrons, and the subshell, which has 5 orbitals with 10 electrons, for a total of 9 orbitals and 18 electrons.
