Carbonic acid dissolves limestone and other rocks. This is an example of _____. chemical errosion

Jet001 [13]

Carbonic acid dissolves limestone and other rocks. This is an example of chemical erosion. An example is in the caves. Caves are formed where rainwater as it falls through the atmosphere absorbs carbon dioxide. The carbon dioxide makes the rain acidic to react it with the limestone bedrock. The rainwater is absorbed by the soil into the ground. Then as it enters through the soil, the rainwater will absorb more carbon dioxide that is produced by the decomposers. The carbon dioxide with water reacts to form carbonic acid. The carbonic acid will react to limestone and dissolves it slowly. As the space become larger, water can enter into it.

How many neutrons and protons are there in the nuclei of the following atoms. a. Li-7 b. O-16 c. Th-232 d. Pu-239

ANEK [815]

Answer:

a.

P = 3 , N = 4

b.

P = 8 , N = 8

c.

P = 90 , N = 142

d.

P = 94 , N = 145

Explanation:

Mass number = Number of protons + Number of neutrons

Also,

Atomic number = Number of protons

<u>Li - 7</u>

Given, Mass number of Lithium = 7

For lithium, atomic number = 3

So,

Number of protons = 3

Number of neutrons = Mass number - Number of protons = 7 - 3 = 4

<u>O - 16</u>

Given, Mass number of oxygen = 16

For oxygen, atomic number = 8

So,

Number of protons = 8

Number of neutrons = Mass number - Number of protons = 16 - 8 = 8

<u>Th - 232</u>

Given, Mass number of Thorium = 232

For Thorium, atomic number = 90

So,

Number of protons = 90

Number of neutrons = Mass number - Number of protons = 232 - 90 = 142

<u>Pu - 239</u>

Given, Mass number of Plutonium = 239

For Plutonium, atomic number = 94

So,

Number of protons = 94

Number of neutrons = Mass number - Number of protons = 239 - 94 = 145

The boiling point of a substance in City A is found to be 145 degrees celcius. The boiling point of the same substance in City B

leva [86]

City B is at a higher temperature because as you go higher in altitude the boiling point of water becomes lower.

How might the yield of 1-bromobutane be affected if water was not added, and what product(s) would be favored?

jek_recluse [69]

Due to the inability of the reaction to take place, the yield of 1-Bromobutane would drop.

Since 1-Butanol won't react with the additional sodium bromide, bromination won't happen.

If water had been supplied, the equilibrium would have shifted extremely far to the left, preventing the reactants from interacting with the acid and favoring the yield of 1-bromobutane instead.

<h3>What is Bromination?</h3>

When a substance undergoes bromination, bromine is added to the compound as a result of the chemical reaction.

After bromination, the result will have different properties from the initial reactant.
For example, an alkene is brominated by electrophilic addition of $Br_{2}$ .
Benzene ring bromination by electrophilic aromatic substitution.
