Answer:
Laboratory acids are far too dangerous to taste, but you will have swallowed some dilute weak acids. Acids have a sour taste, like vinegar, which contains ethanoic acid, and lemons, which contain citric acid. These are safe to use in food, but they can still hurt if they get into a cut or into your eyes.
Explanation:
They can safely be consumed and do not irritate the skin. However, at greater concentrations weak acids can be harmful. Acids can react violently with water and are harmful in the presence of moisture in the mouth or eyes or in proximity with other aqueous solutions.

<span>In order to covert a unit, you must know certain number of conversions. In here, the conversion is in unit of length. One meter is equal to 1000 meter. So if it is in cubic form, then the answer of one meter cube is also equal to 1000 cube. Then,
32 m</span>³ (1000 mm/1m)³
<span>or
</span>32 m³ (1000³ mm³/1 m³)
= 3.2 x 10¹⁰ mm³
Answer:
the mass of the copper piece is 110.2976 grams
Cells can be classified as eukaryotic or prokaryotic. Eukaryotic cells contain membrane-bound organelles, including a nucleus, while prokaryotes do not.
<span>Moles of solid copper used in reaction, using molar mass:
1 gram Cu @ 63.55 g/mol = 0.0157 moles Cu
(f) Moles of solid silver produced in reaction , using molar mass:
3.395g Ag @ 107.87 g/mol = 0.317 moles of Ag
Write the net ionic equation for the reaction between, using your mole values:
0.0157 Cu (s) & 0.317 Ag+ --> 0.0157 Cu+2 & 0.317 Ag (s)
Convert to whole number ratio, by dividing by the smaller :
0.0157 moles Cu / 0.057 = 1 mole Cu
0.317 moles Ag+ / 0.157 = 2 moles Ag
and rewrite the equation using the whole number ratio:
1 Cu (s) & 2 Ag+ --> 1 Cu+2 & 2 Ag (s)</span>
