Answer:
They mostly dissolve in water, and they are poor conductors of heat.
Answer:
1:2:1:2
Explanation:
A molecule is made up of aggregates of small particles called atoms.
CH₄ + 2O₂ → CO₂ + 2H₂O
From the reaction above we have: 1 molecule of methane CH₄ reacting with 2 molecules of oxygen gas O₂ to produce 1 molecule of carbon dioxide gas CO₂ and 2 molecules of H₂O:
CH₄ + 2O₂ → CO₂ + 2H₂O
1 : 2 : 1 : 2
Filling in the gaps in the excerpt below
Molecules that do not __Dissociate__________ (or come apart) in solution are called ___Non-electrolyte substances_________ . Most of these substances are covalently bonded __and do not conduct electricity__________ (e.g., glucose, urea, and creatinine). In contrast, a(n) ___Electrolyte_________ is any substance that dissociates in solution to form Salts
<h3>Difference between electrolytes and Non-electrolytes</h3>
Electrolytes are substances that conduct electricity because they readily ionize when placed in a solution. while Non-electrolytes do not readily conduct electricity because they do not dissociate into ions when placed in a solution.
Hence we can conclude that the answers to your questions are as listed above.

Between a water molecule and an anion, like Cl-, a hydrogen bon occurs between hydrogen atom of the water molecule and the anion.
<h3>What is hydrogen bond?</h3>
Hydrogen bond is a weak bond between two molecules resulting from an electrostatic attraction between a proton in one molecule and an electronegative atom in the other. Hydrogen atom in water molecule attract anion due to presence of hydrogen bond.
So we can conclude that hydrogen bond occurs between hydrogen atom of the water molecule and the anion.
