The molecular formula:
The molecular formula is N₂O₄.
A nuclear reaction changes the number of protons and or neutrons in an atom.
<h3>What do nuclear reactions change in the atom?</h3>
A nuclear reaction is a type of reaction that results in the change of the nucleus of an atom. We know that a nucleus of an atom is made up of protons and neutrons.
So we can conclude that a nuclear reaction changes the number of protons and or neutrons in an atom.

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.
Answer:
The total ionic equation is:
3 Na+ + PO4-3 + 3H+ + 3Cl- --> H3PO4 + 3Na+ + 3 Cl-
And the net ionic equation is:
3H+ + PO4-3 --> H3PO4
Explanation:
In the rock cycle, rocks and matter go through uplift, weathering, erosion, deposition, melting, crystallization, and metamorphism as they travel between Earth's surface and its interior layers
