Answer:
Explanation:
Hello,
In this case, since the rms speed of the molecules is computed by:
Whereas the absolute temperature is computed from the internal energy (by using the Cp of helium (3.1156 J/g*K) as shown below:
Thereby, the rms speed results:
Regards.
Answer:
Amplitude
Explanation:
Transverse waves such as water waves, sound waves and earthquakes usually contain a large amount of energy which is determined by the amplitude.
The amplitude is known as the maximum displacement and its measured in meters. We should also note that the energy of a wave doesn’t affect the wavelength, frequency or speed but only the amplitude.
Answer:
The answer to your question is pH = 5
Explanation:
Data
[H⁺] = 1 x 10⁻⁵
pH = ?
pH is a measure of the hydrogen concentration. It measures the acidity or alkalinity. The range of pH goes from 0 to 14. The pH for an acid is from 0 to 6.9, for a neutral solution is 7.0 and for an alkali is from 7.1 to 14.
Formula
pH = -log [H⁺]
-Substitution
pH = -log [1 x 10⁻⁵]
-Simplification
pH = - (-5)
-Result
pH = 5
The size of the container in which the solution is in.
Balanced chemical reaction 1:
2Cu₂S(s) + 3O₂(g) → 2Cu₂O(s) + 2SO₂<span>(g).
</span>Balanced chemical reaction 2:
Cu₂O(s) + C(s) → 2Cu(s) + CO(g). /·2
2Cu₂O(s) + 2C(s) → 4Cu(s) + 2CO(g)<span>
Balanced net chemical equation:
</span>2Cu₂S(s) + 3O₂(g) + 2C(s) → 4Cu(s) + 2CO(g) + 2SO₂(g).
There 4 atoms of copper, 6 oxygens, 2 sulfur and 2 carbons on both side of reaction.
