Correct AnswerFourth Option, 2518 g
Solution:The formula of number of moles (n) in terms of mass of the compound(m) and molar mass of the compound (M) can be stated as:
We have the number of moles of Octane.
So,
n = 22.05 moles
We have the molar mass of octane.
So,
M=114.22 g/mol
Using these values in the above formula we can calculate mass of Octane (m).
Therefore, the mass of 22.05 moles of Octane is 2518 g.
Answer:
Plasma
Explanation:
Plasma is a substance which is extremely hot. The heat present in plasma, a gas, is provided as energy in order to split electrons and protons apart. Therefore, ions and electrons are formed as products. Plasma is a synonym to an 'ionized gas'.
Normally, the standard states, gases, liquids and solids, wouldn't produce such an outcome, as not enough energy is present to perform the splitting pattern. This can only occur for gases at extremely high temperatures.
Answer:
This solution is called a buffer.
Explanation
It is an aqueous solution containing a weak acid and its conjugate base or a weak base and its conjugate acid. A buffer's pH changes very little when a small amount of strong acid or base is added to it. It is used to prevent any change in the pH of a solution, regardless of solute..
