3.
protium (A = 1), deuterium (A = 2), and tritium (A = 3).
Answer:
(a) The lewis structure for methylisocyanate is in the attached.
(b) The carbonyl carbon have an sp² hybridization
(c) The nitrogen have an sp² hybridization?
Explanation:
(a) The lewis structure for methylisocyanate has the nitrogen with one lone pair and the oxygen with two lone pairs.
(b) The carbonyl carbon form double bond with the oxygen causing to form three hybrid orbitals sp².
The Nitrogen also forms a double bond with the carbon having an sp² hybridization too.
Answer:
Compound
Explanation:
Soda itself is a mixture made out of compounds.
Answer: the density of the solid metal is 22.5176 g/cm
Explanation:
Given that;
mass of solid metal = 255 g
the cylinder and its contents weigh 101g less than before
also given that density of mercury = 13.6 g/cm³
Volume of the solid metal = volume of mercury which was absent in the first weighing
so let volume = Vcm³
Mass of mercury which was absent in the first weighing = density × volume
= 13.6 g/cm³ × Vcm³ = 13.6V g
now since the cylinder and its contents weigh 101g less than before,
it means the difference in mass between the solid and metal and the mass of mercury is equal to 101 g
so
255 - 13.6V g = 101g
13.6V g = 255 g - 101 g
13.6V = 154
V = 154 / 13.6
V = 11.3245 cm³
Now Density of solid metal will be;
⇒ mass / volume
= 255 / 11.3245
= 22.5176 g/cm
Therefore, the density of the solid metal is 22.5176 g/cm
Explanation:
The problem is in balancing the reaction equation;
Li + AlCl₃ → LiCl + Al
In balancing chemical equations, we must keep the law of conservation of matter in mind.
The law shows that the number of atoms on both sides of the reaction must be the same.
To balance the given equation, we set up simple, solvable algebraic mathematical expressions:
aLi + bAlCl₃ → cLiCl + dAl
Coefficients a, b,c and d
Conserving:
Li: a = c
Al: b = d
Cl: 3b = c
let b = 1;
d = 1
c = 3
a = 3
3Li + AlCl₃ → 3LiCl + Al
