Paha777 [63]3 years ago
8 0

Answer;

1) Moleculer solids; I2, S8 and P4 2) Covalent solids; SiO2; 3) Moleculer liquid; H2O 4) Moleculer gas; SO2

Explanation:

In Moleculer compounds the molecules are held together by intermoleculer forces such as van der waals forces and dipole-dipole interaction. They have weak melting and boiling point.

Covelent compounds are held together by covalent bond. They have strong melting and boiling point.

Arisa [49]

Answer:

New pressure P2 = 4.95 atm

Explanation:

Given:

Old volume V1 = 1.50 L

New volume V2 = 0.50 L

Old pressure P1 = 1.65 atm

Find:

New pressure P2

Computation:

P1V1 = P2V2

So,

(1.50)(1.65) = (0.50)(P2)

New pressure P2 = 4.95 atm

A multivitamin tablet contains 40 milligrams of potassium. how many moles of potassium does each tablet contain?
katrin2010 [14]
Conversion of mole to grams
k in mole = 1 mole/ atomic mass
K in mole =1/ 39.0983 g/mole
                = 0.255765 g/mole
converting 40 grams of K
 K 40 grams x [ 1 mole/ 39.0983 grams] = 1.0230623 mole
There are 1.0230623 moles of K in 40 K of Potassium
