Explanation:
A millilitre is equal to the volume of a cube with 1 cm on each side. As a result, one millilitre equals one cubic centimetre. There are 1000 mL in a litre, that is the same as 1000 cm3 in a square metre.
1 ml = 1 cm³
1000 ml = 1 liter
Lydia and Damien will select bases that have a small Kb and which are found in the storage cabinet in solutions with high concentrations.
Explanation:
Before choosing a bottle Lydia and Damien should consult a Kb (base dissociation constant) table of bases. The lower the Kb the weaker the base.
Because they were asked by the profesor to select bottles of concentrated bases they will choose the solution that have the highest concentration. Weak bases that are commonly found in laboratories are triethylamine and pyridine.

Copper (Cu) can have two ion charges: +1 and +2. CuF2 is with the +2 charge, copper (II), and CuF is the opposite.
Answer:
B. The solubility of a gas in a liquid decreases with decreased pressure.
Explanation:
When the pressure is released by opening the soda container, the liquid cannot hold as much carbon dioxide, so the excess bubbles out of the solution. If the soda is left open, additional carbon dioxide will slowly escape into the air. Under warm conditions, the carbon dioxide leaves the solution faster
