Check all that apply. view available hint(s) water is known as a polar molecule because check all that apply. the hydrogen atom

attracts electrons much more strongly than the oxygen atom. the electrons of the covalent bond are not shared equally between the hydrogen and oxygen atoms. the oxygen and hydrogen atoms have the same electronegativity. the oxygen atom has a greater attraction for electrons than the hydrogen atom does. water dipole moment is equal to zero.

The first answer is the electrons of the covalent bond are not shared equally between the hydrogen and oxygen atoms because the hydrogen atoms attract the electrons less strongly. The second answer is the oxygen atom has a greater attraction for electrons than the hydrogen atom does because the nucleus of the oxygen atom has more positively charged protons.

Amiraneli [1.4K]

Answer:

Sodium is a silvery-white metal that reacts with chlorine gas, which is a yellow-greenish gas that is toxic. The  reaction gives off a lot of heat. After the reaction, which statement is true about the chemical properties of the product, sodium chloride?

Pure sodium reacts violently and sometimes explosively with water producing sodium hydroxide, hydrogen gas and heat

2Na(s) + 2H2O(l) → 2NaOH(aq) + H2(g)

Chlorine is a very poisonous yellow green gas with a sharp odour that was used in gas warfare during WW1

Sodium and chlorine reacts with each other, however, to produce one of the most familiar substance used in cooking and preservation industry today Sodium Chloride or Common salt or table salt in the irreversible equation;

2Na(s) + Cl2(g) → 2NaCl(s)

Explanation:

It is easy to see why this reaction takes place so readily sodium has one electron in its outermost valence shell while chlorine has seven electrons in its valence shell. when sodium atom transfers one electron to chlorine atom forming a sodium cation (Na+) and a chloride anion (Cl-) both ions have complete valence shells and are energetically more stable. the reaction is extremely exothermic, producing a bright yellow light and a great deal of heat and fumes of sodium chloride.

In a reaction observation of the reaction process you will see sodium flares up almost immediately upon reaction with water.

What is the pH of a substance with a hydrogen concentration of 1.0 x 10-13?
Nikolay [14]

Answer:

Favorite Answer

1.0 x10^-14 = (1.0 x 10^-13) (x)

x = 1.0 x 10^-1 = 0.1 M (this is the [OH-])

pOH = -log 0.1 = 1.0

Explanation:

I hope this helps :) sorry if not :(
