Elements that form ionic bonds generally have how many valence electrons? ± 1 or ± 2 ± 2 or ± 3 ± 4 ± 5
11111nata11111 [884]

Answer:

± 1 or ± 2

Explanation:

Electrovalent bonds are chemical bonds that are established on the premise of transferring electrons between two atoms.

In this bond type, a higly electronegative atom, typically a non-metal receives electrons from an atom with lesser electronegativity, a metal.

To know the number of electrons involved in forming electrovalent bonds, we typically look at the groups of atoms that combines to form the bond.

Metals are found in group I and II on the periodic table. Metals are electropositive and are good electron donors. These metals have 1 and 2 electrons in their valence shell respectively. In like manners, the more electronegative atoms are found in group VI and VII. The elements in these groups are non-metals with high electronegativity and requires just 1 and 2 electrons to complete their octet.

Describe the number of solutions for the equation. 5(x-9)=5x A. No solution B. One solution C. Infinite solutions Is the answer
Elan Coil [88]
Distribute the 5 to the (x-9), which leaves you with:
5x - 45 = 5x
Subtract 5x from both sides.
This leaves you with:
-45 = 0
which is false, meaning there is no solution to this problem.
The answer is A. No solution

A reaction is expected to produce 28.3 moles of hydrogen gas. If the hydrogen is collected at 297 K and 1.08 atm, what is the vo
Vinil7 [7]

Answer:

The correct answer is 639 L H₂

Explanation:

We use the ideal gas equation:

We have the following data:

n = 28.3 mol

T= 297 K

P= 1.08 atm

R= 0.082 L.atm/K.mol (gas constant)

We introduce the data in the gas equation to calculate the volume (V):

PV=nRT

⇒V =nRT/P = (28.3 mol x 0.082 L.atm/K.mol x 297 K)/(1.08 atm) = 638.2 L ≅ 639 L

Therefore, the correct option is  639 L H₂

3CH4 refers to three molecules of a
compound and C3H12 refers to only one
molecule of a compound.
3CH4 and C3H12 are actually different
molecules though they contain the same
number and types of atoms. Recall that both
of them are hydrocarbons hence they
contain only hydrogen and carbon.
3CH4 refers to three molecules of methane
while C3H12 refers to one molecule of
diphenyl methane. Hence 3CH4 refers to
three molecules of a compound and C3H12
refers to only one molecule of a compound.

What is the ph of a 0.0032 m solution of HCI
kondor19780726 [428]
Hydrochloric acid is a strong acid which means it dissociates into ions when in solution. It's pH can be calculated by taking the negative logarithm of the concentration of the hydrogen ions. The concentration of the H+ ions would be equal to the concentration of the solution since there is a 1:1 relationship.

pH = -log 0.0032
ph = 2.49
