According to the Law of Definite Proportions from Dalton's Atomic Theory, each compound is composed of a fixed ratio of each of its individual elements. So, the number of individual elements per 1 particle of that compound is represented by the subscripts. The answers are as follows:
Table sugar: 12 atoms of carbon, 22 atoms of hydrogen; 11 atoms of oxygen; 45 total atoms
Marble: 1 atom of calcium, 1 atom of carbon; 3 atoms of oxygen; 5 total atoms
Natural gas: 1 atom of carbon, 4 atoms of hydrogen; 5 total atoms
Rubbing alcohol: 3 atoms of carbon, 8 atoms of hydrogen; 1 atom of oxygen; 12 total atoms
Table sugar: 1 atom of silicon; 2 atoms of oxygen; 3 total atoms
Answer:
He is referring to the chromosphere
Explanation:
B. since Phosphorus has an atomic mass of 30.974 (larger) than Magnesium which is 24.305 (smaller)
Answer:
Carbon=5, hydrogen=12, oxygen=16
Explanation:
Carbon=5, hydrogen=12, oxygen=16
In order to effectively count the number of atoms, we look at the equation closely and take note of the stoichiometric coefficients of each reactant as this influences the number of atoms of that element present.
For instance, oxygen is diatomic and has a stoichiometric coefficient of 8. This implies the there are sixteen atoms of oxygen altogether.
Note that the left hand side refers to the reactants side.
The Structural formula for the activated form of caprylic acid is CH3(CH2)6CO2H
<u>Explanation:</u>
- The Structural formula for the activated form of caprylic acid is CH3(CH2)6CO2H.
- Caprylic acid is a medium-chain fatty acid .
- It is mainly found in palm oil, coconut oil and obtained in the milk of certain mammals.
- Caprylic acid is taken for medical treatments like lung-related disorder, acne, obesity, bacterial skin infection, and it is taken as a dietary supplement.
- It is also used in the production of dyes, perfumes, and sanitizers.
- They are also known as octanoic acid.They are also used in the making of esters
