Answer:
30 miles per gallon.
Explanation:
See picture
When the amount of carbon is plotted based on efficiency, the following graph is obtained (see image)
when looking at the graph, it can be seen that the point of lowest emission is presented with the maximum possible efficiency, 30 miles per gallon and this value is 10400 pounds per 15000 cubic miles.
Percent composition is the quantity or number of parts of a component contained in 100 parts of the total.
Given the the total is 100 g, the reported quantities for each component are the same percent.
Then, the percent composition of each as part of the entire sweet peas is:
Carb: 14.5%
Sugar: 5.7%
Diet. fiber: 5.1%
Prot: 5.4%
Fat: 0.4%
The rest to make the 100% is supposed to be water.
You could also find the percent composition in dry basis, which is done in this way (this is not what the question asks but it is good to know it).
Total components without water: 14.5 + 5.7 + 5.1 + 5.4 + 0.4 = 31.1 grams
Now divide each content by the total (31.1) and multiply by 100.
I will do one example:
Carbs: [14.5 / 31.1 ] * 100 = 46.6%
I do hope that no person does this.
Answer:
A compound forms whenever two or more atoms form chemical bonds with each other. The chemical formula for water is H2O, which means each molecule of water consists of one oxygen atom chemically bonded to two hydrogen atoms. Thus, water is a compound. It's also a molecule, which is any chemical species formed by two or more atoms chemically bonded to each other. The terms "molecule" and "compound" mean the same thing and can be used interchangeably.
Sometimes confusion arises because the definitions of molecule and compound haven't always been so clear-cut. In the past, some schools taught that molecules consisted of atoms bonded via covalent chemical bonds, while compounds were formed via ionic bonds. The hydrogen and oxygen atoms in water are covalently bonded, so under these older definitions, water would be a molecule but not a compound. An example of a compound would be table salt, NaCl. But, as scientists came to understand chemical bonding better, the line between ionic and covalent bonds became fuzzier. Also, some molecules contain both ionic and covalent bonds between the various atoms.
In summary, the modern definition of a compound is a type of molecule consisting of at least two different types of atoms. By this definition, water is both a molecule and a compound. Oxygen gas (O2) and ozone (O3), for example, are substances that are molecules but not compounds.

I've been asked something kind of like this before, not exactly though. But, I hope this answers your question!
