There are 41.1984 grams of silver in 2.3x 10^23 atoms of silver
Answer:
4046atm
Explanation:
For this question you can use the ideal gas law,
<em />
<em />
Where P is pressure, V is volume, n is moles of substance, R is the constant, and T is the temperature.
Because of the units given, R will equal .08026
<h3>Rearrange the equation to solve for pressure:</h3>
Then, plug in the values (I'll be excluding units for simplicity, but they all cancel out for pressure in atm):
This will give you:
a thing, especially a trend or fact, that indicates the state or level of something.
Answer: balloon contains 2600 × 0.1755 = 456.3 kilogram of helium.
Explanation:
Answer is: a bottle of acetic acid contains a solid.
Acetic or ethanoic acid (CH₃COOH) when undiluted is called glacial acetic acid.
Glacial acetic acid has freezing point (melting point) around 16.6°C, so it will be at solit state.
Vinegar is mixture of acetic acid (CH₃COOH) and water (H₂O). Vinegar is colourless liquid with sour taste and pungent smell, freezing point of the vinegar is lower than glacial acetic acid.
Acetic acid dissociate in aqueous solution to form hydrogen ions (H⁺) and acetic anion (CH₃COO⁻).
Balanced chemical reaction (dissociation):
CH₃COOH(aq) ⇄ CH₃COO⁻(aq) + H⁺(aq).
