On the Moon<span>, there is (as on </span>Earth) day and night (though the day is as long as month onEarth<span>) and no spot remains </span>dark<span> for longer (except for the pole caps as on </span>Earth<span>). There is, of course, the far </span>side of the Moon<span>, most of which is invisible from </span>Earth.
i believe that it is the third one
Answer:
Here's what I get
Explanation:
There are two methods of naming esters.
(a) Common names
alkyl alcohol + carboxylic acid ⟶ alkyl carboxylate
To form the name of an ester, you drop the alcohol and -ic acid ending from the names of the reactants.
The name of the ester consists of two words: the name of the alcohol followed by the acid name with the ending -ate.
(b) IUPAC (systematic) names
alkanol + alkanoic acid ⟶ alkyl alkanoate
To form the name of an ester, you drop the -anol and -ic acid endings from the names of the reactants.
The name of the ester consists of two words with the corresponding endings -yl and -ate.
You don't mix the common and IUPAC systems in the same name.
1. ethanol + benzoic acid ⟶ ethyl benzoate
2. benzyl alcohol + acetic acid ⟶ benzyl acetate
3. butanol + butanoic acid ⟶ butyl butanoate (IUPAC)
butyl alcohol + butyric acid ⟶ butyl butyrate (common)
4. pentanol + propanoic acid ⟶ pentyl propanoate (IUPAC)
n-pentyl alcohol + propionic acid ⟶ n-pentyl propionate (common)
5. isopropyl alcohol + formic acid ⟶ isopropyl formate
Limiting factor- Food, Pollution, Predators.
Outcome variable (dependent variable): Cricket Frog (population)
Control group: Cricket Frogs in the Florida Everglades without changes in or manipulation of the population.
Pure substance is only one type of atom or molecule. A mixture is a bunch of different atoms together
