Answer:

Covalent

Step-by-step explanation:

Covalent substances have relatively weak intermolecular forces. Many covalent substances such as hydrogen and oxygen are gases at room temperature, so they have low melting points.

Ionic substances have strong ion-ion attractive forces, and metals have strong metallic (electron-metal cation) attractions. I don't know of any metals or ionic compounds that are gases at normal conditions.

How many moles of hcl are present in 40.0 ml of a 0.035 m solution?

Elden [556K]

Answer:

0.0014 moles is present in 40cm³ of 0.035M of HCl solution

Explanation:

Molarity = 0.035M

V = 40.0mL

1mL = 1cm³

V = 40cm³

0.035 moles = 1000cm³

X moles is present in 40cm³

X = (40 * 0.035) / 1000

X = 0.0014moles

0.0014 moles is present in 40cm³ of solution
