Single replacement, one atom takes the place of another. There’s one element and one compound and they switch
element + compound —> (and then either the +ions switch with each other or the -ions)
A+BC—> AC + B
Answer: The students should take 49.67 g acid acetic in benzene solution. With significant digits 4.967X10 g.
Explanation: If 220 g solution 30.2% w/w acetic acid has 66.44 g acid acetic (220 g solution * 30.2%), 49.67 g solution 30.2% acetic acid has 15 g acetic acid (with a simple three rule, 15 g acetic acid*220 g solution/66.44 g acetic acid)
Answer:
the last one is the correct anwser
Nitrates and chlorides are highly soluble, whereas sulfates and phosphates are less soluble along with the common ions used in medicine.
<u>Explanation:</u>
Mostly calcium and magnesium salts are utilized in medications. On the basis of the solubility rules, chlorides and nitrates are highly soluble also have few precipitates among the metal salts.
But, sulfates produces a lower solubility salt with calcium, generally in many medications.Additionally phosphate forms the low solubility salts along with Magnesium and calcium that are used in medications.
