Which properties describe water? strong surface tension, weak surface tension, denser as a solid, denser as a liquid, nonpolar, polar, covalent bonds, or ionic bonds

Strong Surface Tension, Covalent Bonds, Denser as a Liquid, Polar.

Explanation:

Water is a polar substance with strong surface tension. It is denser as a liquid than as a solid. A water molecule consists of a hydrogen atom covalently bonded to two oxygen atoms.

"a connection, a bond or common feeling between two people", or as a chemical process it stimulates love or sexual attraction

1. for the first question, we must find the mass of the anhydrous salt, mgso₄. the molar mass for mgso₄·7h₂o is 246.47 g/mol, while that of mgso₄ is 120.37 g/mol.7.834 g mgso₄·7h₂o * 1 mol mgso₄·7h₂o/246.47 g * 1 mol mgso₄/1 mol mgso₄·7h₂o * 20.37 g mgso₄/mol = 0.647 g mgso₄

2. mass of water = mass of sample - mass of anhydrous salemass of water = 7.834 - 0.647 = 7.19 gpercent water in hydrate = 7.19/7.834 * 100 = 91.74%
