Answer:
Joseph Black discovered carbon dioxide.
Explanation:
Answer:
The density is 10.25
Explanation:
From the question we are given that the lattice spacing nm
V = ×
= 0.1628
zinc blende lattice has 4 atom per unit cell.
This means that 4 atoms is contained in 0.15056
Density of the cubic unit in terms of atom is given as =
=26.565
For plane (110) the spacing between the cubic unit in the crystal denoted by is given as = Where a is the lattic spacing = 0.546
= = 0.376 nm
The density of the lattice in (110) plane =26.565 × 0.386 nm
= 10.25
In my point of view, the simple thing to do here is just to exchange the 3+ and the 2- and you will get:
Al2(CO3)3
The logic behind this is that when you have 2 Al^3+, it makes an overall charge of 6+. Additionally, when you have 3 CO^2-, it also makes an overall charge of 6- (because 3 X 2 = 6). Therefore, 6+ and 6- "cancelled" out, and you will have a neutral charge compound.
