Answer:
The molecular geometry of SO3 is trigonal planar.
Explanation:
Look at the Lewis
Alkali metals have the lowest electronegativities, while halogens have the highest.
Answer:
6.022 × 10²² atoms
Explanation:
Generally 1 mol of any element contains 6.02×10^23 atoms. The number 6.022 × 10²³ is known as Avogadro's number.
Mass of Aluminium = 2.70g
Molar mass = 27g/mol
Number of moles = Mass / Molar mass = 2.70 / 27 = 0.1 mol
1 mol = 6.022 × 10²³
0.1 mol = x
x = 6.022 × 10²³ * 0.1 = 6.022 × 10²² atoms
Answer: the answer is a netrual bond
Explanation: a netural bond happens when the number of electrons are the same as the number of protons.
