Ksivusya [100]3 years ago
4 0

Answer:

Li_2O

Explanation:

Hello!

In this case, when looking over the chemical formula of a compound formed when two elements interact, we need to realize about their location in the periodic table; thus, since lithium is a metal and oxygen a nonmetal, we infer lithium turns out the cation and oxygen the anion. Moreover, as the oxidation state of lithium is 1+ and that of oxygen is 2-, we can set up the chemical formula as follows:

Li^+O^{2-}\\\\Li_2O

Best regards!

Write a resonance form for pyrrole in which nitrogen has a formal charge of 1. Are comparable resonance forms possible for pyrid
Svetach [21]

Answer:

See explanation and image attached

Explanation:

Here attached are resonance forms of pyrrole and pyridine. The images were obtained from quora and researchgate respectively.

Now, we can see that in the resonance forms of pyrrole, the nitrogen atom in the heterocycle has a formal charge of +1. However, in the six membered pyridine hetrocycle, the nitrogen atom may have a formal charge of -1 or +1 as shown in the canonical structures attached. The structures in which nitrogen has a +1 formal charge in pyridine are comparable to structures obtained from pyrrole. These structures have less contribution to the structure of pyridine.

Which of the following is false? Charged molecules are insoluble in water. Hydrophobic molecules tend to be nonpolar and hydroph
inysia [295]

Answer:

Number 1 is false

Explanation:

1.- Charged molecules are insoluble in water. The statement is false, charged molecules are soluble in water and this is the main characteristic of charged molecules.

2.- Hydrophobic molecules tend to be nonpolar and hydrophilic molecules tend to be polar. This is true, hydrophobic molecules are non polar and hydrophilic molecules are polar.

3.- Gasoline has partial positive and negative charges which allows it to dissolve in water. This is true, gasoline is soluble in water.

4.- NH3 dissolves in water because its molecules form hydrogen bonds with water. This is true, NH3 interact with water because they can form hydrogen bonds.

5.- Hydrophobic molecules prefer to interact with each other in an aqueous solution. Absolutely true, hydrophobic molecules interact among them and they isolate from the environment.

The empirical formula that contains 120 g of carbon and 30.3 g of hydrogen
hoa [83]

Answer:

Empirical formula is CH₃.

Explanation:

Given data:

Mass of carbon = 120 g

Mass of hydrogen = 30.3 g

Empirical formula = ?

Solution:

Number of gram atoms of C = 120 g / 12 g/mol = 10

Number of gram atoms of H = 30.3 g / 1.008 g/mol = 30.06

Atomic ratio:

                   C             :            H            

                10/10          :       30.06/10

                   1              :            3.06    

C : H  = 1 : 3

Empirical formula is CH₃.
