Answer:
CCl4
Explanation:
Because the size of the molecule and the inter molecular forces are greater than the others.
(6.0×10^4) = 60,000
(3.1×10^-1) = 0.31
60,000 × 0.31 = 18,600
Diamond consists of carbon atoms tetrahedrally arranged and bonded by strong covalent bonds. Graphite consists of carbon atoms arranged in hexagonal rings and in layers. Each carbon atom is bonded to three other atoms arranged hexagonally in layers.
Answer:
32.7 grams of Zn will remained in the crucible after cooling.
Explanation:
..[1]
..[2]
Adding [1] + 2 × [2] we get:
..[3]
Moles of ZnS in crucible = 0.50 mol
According to reaction [3]. 2 moles of ZnS gives 2 moles of Zn.
Then 0.50 moles of ZnS will give:
of Zn.
Mass of 0.50 moles of Zn =
= 0.50 mol × 65.4 g/mol =32.7 g
32.7 grams of Zn will remained in the crucible after cooling.
Answer:
Pure substances are further broken down into elements and compounds. Mixtures are physically combined structures that can be separated into their original components. A chemical substance is composed of one type of atom or molecule.
