Hey there!
Numbers written in scientific notation are written in two parts.
First, we have the digits usually with a decimal. This number must be at least one and less than ten.
The second part is x 10 to a power. This power is the number of places the decimal has been moved.
To get a number at least one and less than 10, we would have to move the decimal place on this number 13 places to the left to get 5.928.
Because we move the decimal 13 places, the power of 10 is 13.
5.928 x 10¹³
Hope this helps!

Hello there!
In this case, according to the given information, it turns out possible to set up the initial version of the half-reaction as follows:
Now, we assign the oxidation numbers to both nitrogen atoms:
It means three electrons are carried, two water molecules are needed on the left side in order to balance the oxygen atoms and consequently four hydronium ions to balance hydrogen atoms in acidic media:

Answer:
When fuels are burned in vehicle engines, high temperatures are reached. At these high temperatures, nitrogen and oxygen from the air combine to produce nitrogen monoxide. When this nitrogen monoxide is released from vehicle exhaust systems, it combines with oxygen in the air to form nitrogen dioxide.

Mercury (ii) oxide is made up of mercury and oxygen. The total mass of mercury (ii) oxide is 14.2 g, after decomposition 13.2 g of mercury were formed, therefore the mass of oxygen 1 g (14.2 g -13.2 g).
Percentage of oxygen = (1/14.2)×100 = 7.04%
Percentage of mercury = (13.2/14.2) × 100 = 92.96%
Therefore, percentage composition of the compound, oxygen is 7.04% and mercury is 92.96%.
