Carbon can share a maximum of how many of its valence electrons when bonding to other atoms?2

4

6

Cannot be determined

Answers

Answer 1
Answer:

Carbon can share a maximum of four of its valence electrons when bonding to other atoms. This is the reason why organic molecules can be so large because of this bonding. Suppose you have a compound of CCl4. You know that chlorine can only share 1 electron because 7 of its electrons are filled. Also, in carbon, it can only share 4 electrons because 4 of it are already filled. That is why carbon needs four chlorine to form CCl4.

- Answer:

Answers

Based on the calculation, the velocity of this wave is equal to 420 m/s.

Given the following data:

  • Frequency of turning fork = 280 hertz.
  • Wavelength of sound produced = 1.5 meters.

How to calculate the velocity of a wave?

Mathematically, the velocity of a wave is calculated by using this formula:

V = λF

Where:

  • F is the frequency of a wave.
  • V is the velocity of a wave.
  • λ is the wavelength of a wave.

Substituting the given parameters into the formula, we have;

V = 1.5 × 280

V = 420 m/s.

Note: You should use the above formula to solve the other questions.

Which substance is a binary acid

Answers

It is knownthat acids compounds contains hydrogen and produces hydrogen ion in water. A binaryacid however is an acid that have two elements, one of the element has ahydrogen attached to it. Examples of binary acids are hydrogen fluoride (HF),hydrogen bromide (HBr) and hydrogen sulfide (H2S). In naming a binary acid, ithas two rules; one, as pure compounds and two, as acid solutions. For purecompounds, start with the name ‘hydrogen’ and end the anion name with ‘-ide’. Foracidic compounds, start with ‘hydro-‘, end the anion with ‘-ic’ and add ‘acid’.

What are 5 examples of gases found at home?

Answers

Examples of gases that can be found at home include carbon monoxide, chlorine, ammonia, hydrogen, nitrogen, and sulfur oxides.

  • Gas is one of the three states of matter that we've. A gas simply means a substance that doesn't have a fixed shape and fixed volume.

  • It should also be noted that gases have lower density when compared to solid or liquid. There are different gases such as oxygen, nitrogen, helium, carbon monoxide, etc.

  • Examples of gases found at home include carbon monoxide, chlorine, ammonia, hydrogen, nitrogen, and sulfur oxides.

In conclusion, carbon monoxide is gotten when we burn wood, charcoal, fuel, etc.
