I need help if anyone will help plz

maksim [4K]

Answer:

D

Explanation:

If you look at the problem, and the coefficients (the little numbers on the bottom) you will see that on the reactant side you get a total of 11, you look over to the product side and you also get a total of 11.

B. is wrong because they’re are the same amounts

C.is wrong because they have the same amount of carbon

D. Now similar to B but slightly different the matter is the reactant side I’m pretty sure is equal to the amount on the product side.

If I had to take a strong guess though I would choose D just because the question is asking for the one that shows The law of conservation of mass. Pls make me brainlist

All atoms of the same element:

34kurt

Answer:

have the same number of protons

Explanation:

Atoms of the same element will always have the same number of protons.

Protons are the positively charged particles in an atom which are located in the nucleus.

To recognize an atom, the number of protons is used.
The number of protons is the atomic number.
On the periodic table, atoms are arranged based on the number of protons.

A scientist has isolated a fatty acid that has 26 carbons. most of the carbon atoms in the fatty acid chain are connected by sin

Shtirlitz [24]

Answer:
Based on giveninformation, the compound is a Poly Unsaturated fatty acid.

Explanation:
Fatty acids are carboxylic acids with -COOH functional group and a chain of hydrocarbons.

Fatty Acids are classified as,

i) Saturated Fatty Acids:
Those Fatty Acids in which there is no double bond between the carbon chain are called as saturated fatty acids.

Examples:
Lauric Acid CH₃(CH₂)₁₀COOH

Myristic Acid CH₃(CH₂)₁₂COOH

Palmitic Acid CH₃(CH₂)₁₄COOH

ii) Unsaturated Fatty Acids:
Those Fatty Acids in which contain a single double bond (mono-unsaturated) or more than one double bond (poly-unsaturated) d between the carbon atoms in a chain are called as unsaturated fatty acids.

Examples:
Linoleic acid

Vaccenic acid

Palmitoleic acid

The saturated fatty acid containing 26 carbon atoms is called as Cerotic acid. While cerotic acid containing a double bond at position 3 and 9 has a IUPAC name Hexacosa-3,9-dienoic acid with following structure.

The chemical reaction shown here, in which a large molecule is broken down into the smaller parts that make it up, is called a _

Triss [41]

I believe such reactions are called decomposition reactions. Decomposition reactions are reactions that involve breaking down a compound into smaller compounds or individual elements. They involve input of energy in the form of heat, electricity or light to break down the compounds. When light is used the reaction is referred to as photo decomposition while when heat is used the reaction is thermal decomposition reaction e.t.c. The general form of the reaction is AB = A + B.
