Why carbon is a basic thing to classify as organic and inorganic compounds?​

Answers

Answer 1
Answer:

Answer:

To answer, all living organisms contain carbon-based compounds, which classifies them organic.

Simply, carbon dioxide, is an example of an inorganic compound since it does not contain both carbon and hydrogen. Alternatively, one molecule of carbon dioxide contains one atom of carbon and two atoms of oxygen.

out of barium, chlorine, iodine, and strontium which atom has the strongest attraction for electrons in a bond formation?

Answers

Out of the choices given, the correct answer would be chlorine. It is the atom with the strongest attraction for electrons in a bond formation. This is because it has the highest electronegativity among the choices.

Which is a characteristic property of acids? A-they, turn blue litmus paper red . B-they, turn red litmus paper blue. C-they tastes bitter D-they don't react with metals

Answers

Answer:

Option A

Explanation:

Option A - Blue litmus paper turns red under acidic conditions so this option is correct.

Option B - Acids do not turn red litmus paper red, bases are the ones responsible for that. Hence, this option is incorrect.

Option C - Acids generally taste sour due to the sour H+ ion; bases taste bitter due to the OH- ion. This option is incorrect.

Option D - This option is incorrect as acid reacts with metal, to form salt and hydrogen.
They turn blue litmus paper to red.

They also taste sour.

What is the balanced equation that represents the reaction between hydrogen and nitrogen to make ammonia (NH3)?

Answers

The balanced equation of the reaction between hydrogen and nitrogen to produce ammonia would be: N_2 + 3H_2 --->2 NH_3

Ammonia is produced when nitrogen reacts with hydrogen.

Stoichiometrically, 1 mole of nitrogen is required to react with 3 moles of hydrogen with 2 moles of ammonia being the product.

Thus, the balanced chemical equation for the reaction would become:

N_2 + 3H_2 --->2 NH_3

Answer:

Balanced chemical equation:

N₂ + 3H₂    →   2NH₃

Explanation:

Chemical equation:

N₂ + H₂    →   NH₃

Balanced chemical equation:

N₂ + 3H₂    →   2NH₃

Step1:

Left side of equation                      Right side of equation

N = 2                                                     N = 1

H =  2                                                    H = 3

Step 2:

N₂ + H₂    →   2NH₃

Left side of equation                      Right side of equation

N = 2                                                     N = 2

H =  2                                                    H = 6

Step 3:

N₂ + 3H₂    →   2NH₃

Left side of equation                      Right side of equation

N = 2                                                     N = 2

H =  6                                                    H = 6

Which value is most likely to be the pH of a salt that is formed by the reaction of a strong acid and a weak base?2.0
7.0
8.0
10.0

Answers

Answer:  2.0 (acidic solution)

Explanation:  When a salt is formed by the reaction of strong acid and a weak base , it will be acidic in nature and thereby its pH will be less than 7.

In the process, conjugate acid will be formed which will react with water to give the hydronium ion (H_{_{3}}O ^{+})

Thus as the positive ion species is increasing, it will make the solution acidic in nature.

The pH value of a salt that is formed by the reaction of a strong acid and a weak base is:  2.0 (acidic solution)

Meaning of pH Value

pH value is a value on the pH scale that tells us how acidic or basic a solution can be.

When a salt is formed by the reaction of strong acid and a weak base , it will be acidic in nature and thereby its pH will be less than 7.

In conclusion, The pH value of a salt that is formed by the reaction of a strong acid and a weak base is:  2.0 (acidic solution)

An atomic nucleus must contain at least one neutron or else the force of attraction of the electron(s) will collapse the atom. True/false

Answers

True. If the nucleus had only protons and electrons, they would stick together like a magnet and collapse the atom.
True the neutron is neutral meaning it doesnt do anything but keep the balance in check
