Alkanes are hydrocarbons that only contain single bonds in them. A carbon can bond with up to 4 atoms, even with another carbon atom. So, in a C-C bond, 3 more H atoms can bond to each of the C atom. Generally, the chemical formula for alkanes is CₓH₂ₓ₊₂. So for butane, there are 4 C atoms. The corresponding H atoms are 2(4) + 2 = 10. That's why it's chemical formula is C₄H₁₀.
Answer:
I don't know if this will help but. The Great Sphinx has suffered from erosion and vandalism. Hatshepsut's stepson was too young to rule at the time of her husband's death, so she just took the job.
<u>Answer:</u> The correct answer is Option B.
<u>Explanation:</u>
Decomposition is a type of chemical reaction in which larger compound breaks down into two or more smaller compounds.

Double displacement reactions is defined as the chemical reaction in which exchange of ions takes place.

Synthesis reaction is a type of reaction in which two or more smaller compounds combines to form a single large compound.

Single displacement reaction is a type of reaction in which a more reactive metal displaces a less reactive metal from its chemical reaction.

In stomach, an acid is present known as hydrochloric acid and to neutralize its effect, antacid is taken which has
as a component.
The reaction between HCl and
is a type of neutralization reaction and it is a type of double displacement reaction.
The equation between the two follows:

Hence, the correct answer is Option B.
