Answer:
The age of ship is 1900 years.
Explanation:
The half life period of carbon - 14 is 5730 years
Ship have 67 % of the concentration of Carbon-14
And the ship lost (100- 67 = 33%) 33% of carbon - 14.
Therefore,
The age of ship = lost percentage X half life period of carbon -14
Therefore, The age of ship is 1900 years.
According to Arrhenius theory, acid is a substance that releases H⁺ ions when dissolved in water.
In order to apply this theory, the substance must be soluble in water.
H₂SO₄ is highly soluble in water. It undergoes following dissociation reaction when dissolved in water.
From the above equation, we can see that H₂SO₄ forms 2 H⁺ ions when dissolved in water. Therefore it behaves as an acid according to Arrhenius theory.

To determine the fraction of the hydrogen atom's mass that is in the nucleus, we have to keep in mind that a Hydrogen atom has 1 proton and 1 electron. Protons are in the nucleus while electrons are in electron shells surrounding the nucleus. The mass of the nucleus will be equal to the mass of 1 proton and we can express the fraction as follows:
So, the fraction of the hydrogen atom's mass that is in the nucleus is 0,9995. That means that almost all the mass of this atom is at the nucleus.
Have a nice day!
