According to www.healthline.com: “Magnesium stearate is an additive that's primarily used in medication capsules. It's considered a “flow agent.” It prevents the individual ingredients in a capsule from sticking to each other and the machine that creates the capsules. It helps improve the consistency and quality control of medication capsules.”

Answer:
1.39x10⁻⁶ mol
Explanation:
First we <u>convert the gallon of juice to liters</u>:
Then we <u>calculate the mass of antimony that would be in 3.785 L</u>, using the <em>given concentration</em>:
- 44.7 μg/L * 3.785 L = 169.2 μg
Then we <u>convert mass into moles</u>, using the <em>molecular mass</em>:
- 169.2 μg ÷ 121.76 μg/μmol = 1.39 μmol
Finally we <u>convert μmol into mol</u>:
- 1.39 μmol = 1.39x10⁻⁶ mol
Answer:
In the reaction ocurrs a nucleophilic substitution of a primary alkyl bromide, where the nucleophile is CH3O-.
Explanation:
Nucleophilic substitution is a type of substitution reaction in which a nucleophile replaces an atom or group in an electrophilic position of a molecule, called a leaving group.
It is a type of fundamental reaction in organic chemistry, where the reaction occurs on an electrophilic carbon. Although nucleophilic substitution reactions can also take place on covalent inorganic compounds.
Following the ideal gas law PV =
nRT, and changing it in terms of temperature, we get T = PV/nR. When volume of
a sample of an ideal gas to double when the pressure of the sample remains the
same, the temperature doubles because temperature is directly proportional with
pressure and volume.
