Here is a more complex redox reaction involving the dichromate ion in acidic solution: 3N O 2 − + 8H + + C r 2 O 7 2− → 3N O 3 −
Fantom [35]

Answer:

NO2- is the reducing agent.

Cr2O7_2- is the oxidizing agent.

H+ is neither

Explanation:

Reduction is the gain in electron. A chemical specie that undergoes reduction is called the oxidizing agent.

Oxidation is simply the loss in electrons. A chemical specie that undergoes oxidation is called the reducing agent.

Let us look at the species.

The first specie is the NO2-. In this specie, the oxidation number of nitrogen changed from +3 to +5 in NO3-. Thus we can see that there is more loss of electron to have caused an increase in the oxidation number positively. This shows an oxidation. Hence, NO2- is the reducing agent.

Let us look at the chromium. We can see that the oxidation number of chromium changed from +7 to +3.

Now we can see that it is a decrease and hence, it is a gain of electron and thus it is reduction. This means the first chromium specie is the oxidizing agent.

The hydrogen ion is simply placed there to balance the ions and hence it is neither the oxidizing nor the reducing agent.

A 38.6 kg marble slab is shown above. What is its density? Give your answer to the nearest tenth.
LuckyWell [14K]

Answer:

Density, d=26.7\ g/cm^3

Explanation:

The attached figure shows a 38.6 kg marble slab. The dimensions of the marble slab is 23 cm × 17 cm × 4 cm

Density = mass/volume

Volume of a cuboid shape is equal to, V = 23 cm × 17 cm × 4 cm

V = 1564 cm³

Density,

d=\dfrac{38.6\times 10^3\ g}{1564\ cm^3}\\\\d=24.68\ g/cm^3

or

d=26.7\ g/cm^3

So, the density of the marble slab is 26.7\ g/cm^3.

Why can you change physical properties and not make a new substance but can't change chemical properties and stay the same?
maxonik [38]

Answer:

Well this has a good chance of being wrong but i wanna say,

When you change a physical property of something it doesn't affect the chemicals that make it up. Like Ice, you can freeze water to make ice. You change a physical property (state of matter) but it's chemical properties don't change because in the end it's still water.

However if you remove a chemical property from something you are changing what made the new substance with will also change the substance along with it.

That's just what I think though
