When an acid reacts with a base what compounds are formed?

Draw the Lewis structure (including all lone pair electrons and any formal charges) for one of the four possible isomers of C3H9

Alexus [3.1K]

Answer and Explanation

The isomer picked is the N-Propylamine.

It has a lone pair of electron available on the electron rich Nitrogen and no formal charge.

Since it will be hard to draw the Lewis structure in this answer format, I'll attach a picture of the Lewis structure to this answer.

The lone pair of electron is shown by the two dots on the Nitrogen atom.

Across:

10. The circulatory system transfers nutrients, gases, liquids, and heat around the body.

11. The circulatory system transports heat, which helps regulate temperature.

13. The place where oxygen enters the blood and carbon dioxide leaves the blood. Lungs.

15. A gas that is transported in arteries from the lungs to the rest of the body via the heart. Oxygen.

Down:

2. The heart, blood, and vessels. Circulatory System.

4. Blood in arteries is bright red because it is rich in oxygen.

6. A waste gas that is transported in veins from the body to the lungs via the heart. Carbon di Oxide.

Explanation:

The circulatory system includes blood vessels, blood, and heart. This system provides the body tissues with oxygen and some nutrients. It also carries hormones and eliminates needless waste products.

This transportation takes place between the cells via blood throughout the body. The channel that blood passes through is a blood vessel that is pumped by an organ called heart. The heart directs the blood passing all over the body.

The lungs are a duo of air-filled, spongy organs positioned on both sides of a human's chest. Its main function is to take in air present in the atmosphere and transfer oxygen to the bloodstream. From where it gets circulated throughout the body.

Two aqueous sulfuric acid solutions containing 20.0 wt% H2SO4

kozerog [31]

Answer:

The feed ratio (liters 20% solution/liter 60% solution) is 3,08

Explanation:

In this problem you have a 20,0 wt% H₂SO₄ and a 60,0 wt% H₂SO₄ solutions.

100 kg of 20% solution are 100kg/1,139 kg/L = 87,8 L 

100kg×20wt% = 20 kg H₂SO₄. In moles:

20 kg H₂SO₄ × (1 kmol/98,08 kg) = 0,2039 kmol H₂SO₄≡ 203,9 mol

The final molarity 4,00M comes from:

$\frac{203,9 moles+ Xmoles}{87,8L + Yliters}$ (1)

Where X moles and Y liters comes from 60,0 wt% H₂SO₄

100 L of 60,0 wt% H₂SO₄ are:

100L× $\frac{1,498 kgsolution}{L}$ × $\frac{60 kg H_{2}SO_{4}}{100kgSolution}$ × $\frac{1kmol}{98,08kg H_{2}SO_{4}}$ = 0,9164 kmolH₂SO₄ ≡ 916,4 moles
