Answer:

If you increase temperature, you increase entropy. (1) More energy put into a system excites the molecules and the amount of random activity. (2) As a gas expands in a system, entropy increases.

how many milliliters of 1.50 m hno3 contain enough nitric acid to dissolve an old copper penny with a mass of 3.94 g?

Lerok [7]

Molar mass HNO₃ = 63.0 g/mol

number of moles = 3.94 / 63.0 => 0.0625 moles

Volume = moles / molarity

V = 0.0625 / 1.50

V = 0.04166 L x 1000 = 41.66 mL

hope this helps!

________ are weak bonds that are not strong enough to hold atoms together to form molecules but are strong enough to form bonds

olga_2 [115]

Hydrogen bonds are weak bonds that are not strong enough to hold atoms together to form molecules but are strong enough to form bonds within and around large molecules.

The hydrogen bond is weak bond.

The hydrogen bond is electrostatic force of attraction between hydrogen atom and more electronegative atoms or group ( like Florine , oxygen or nitrogen) which is contently bonded.
The hydrogen bond is occur in polar , contently bond atoms in different molecules.
Example is H-O-H or $NH_{3}$
The positively charged hydrogen side of one water molecule is bond with negatively charged oxygen side of another molecule.
