Answer:
It is used to make medicine. People take malic acid by mouth for tiredness and fibromyalgia. In foods, malic acid is used as a flavoring agent to give food a tart taste. In manufacturing, malic acid is used to adjust the acidity of cosmetics.
Explanation:
hope it helps
3 of them left and i just need points lol sorrrry
First, we have to find the chemical formula for zinc ion and phosphate ion.
Zinc ion is a cation, and its formula is Zn^2+,
This is because zinc atom requires 2 outer shell electrons to be removed in order to become stable.
On the other hand, phosphate ion is a anion, and its formula is PO4^3-.
In order to find the chemical formula of this ionic bond, we need to make sure their charges are balanced.
To do this, take 2+ and 3-, their least common multiple is 6, so in order to turn both charges into 6+ and 6-, we need to determine how many of that ion is needed.
So to make 2+ to 6+, we need 3 zinc ions ( +2 x 3 = 6).
And to make 3- to 6-, we need 2 phosphate ions (-3 x 2 = - 6).
Now we can just combine the chemical formulas with the number of that ion needed (you can ignore the charge)
Therefore, your answer should be Zn3(PO4)2.
To solve this, we need the Avogadros number to convert to
moles then multiply with molar mass to convert to mass in grams.
moles = 9.3 x 10^23 molecules * (1 mol / 6.022 x 10^23
molecules)
moles = 1.54 moles
Molar mass of NH3 is 17 g/mol:
mass = 1.54 moles * 17 g/mol
<span>mass = 26.25 g</span>
