A 2.70 gram block of aluminum had a volume of 1.0 cm^3. What is its density

d = 2.70 g/cm^3

Explanation:

d = m/v

d = 2.70/1.0

d = 2.70 g/cm^3

b. acid is the correct answer @jayxboof all social media

acid : acids are those which accepts an electron-pairs.

base : bases are those which donates ab electron-pairs.

alkali : it is a base that dissolves in water. it is basically a base and the ph greater than 7.

hydroxide ion : it is a poly-atomic ion which is negatively charged.

it forms an anion that has a larger radius. anions have a negative charge and are larger than the original atom.
