Answer:

Explanation:

Hello!!

Please remember that density=mass/volume.

In this case, we have the same mass for the feathers and the gold (1 pound).

So, if the mass is the same for both we have:

Df*Vg=Dg*Vf where f means feathers and g means gold.

In this case we see density is inversely related to volume. Both materials have the same mass. So which one have a bigger volume?

For this take a pound of feathers and submerge in a known volume of water. Note the displacement. Do the same for a pound of gold. Whichever has the smaller displacement, has the greater density.

In this case, Gold has the greatest density.

Which of the following sets of empirícal formula, molar mass, and molecular formula is correct?

skad [1K]

Answer:

The option C is correct.
CH4N, 90g, C3H12N3.

Explanation:

Option C:

The molecular formula is C3H12N3.

If we take ratio 3:12:3 that will be equal to 1:4:1 so its empirical formula will be CH4N.
The molar mass of molecular formula = (12×3) + (1×12) +( 14×3) = 98 g

Option A :

In option A , molecular and empirical formula are both correct but molar mass is not valid. It should be 169 acc. to molecular formula.

Option B:

In option B, molecular formual is not valid.
It should be as C6H16O2

What statement is incorrect about this oxidation-reduction reaction? 2 SO2(g) + O2(g) → 2 SO3(g) What statement is incorrect abo

Leno4ka [110]

Answer:

The incorrect statement is: SO₂ gains electrons

Explanation:

A chemical reaction that involves the simultaneous transfer of electrons between two chemical species, is known as the redox reaction.

Given chemical reaction: 2SO₂(g) + O₂(g) → 2SO₃(g)

In this redox reaction, S is present in +4 oxidation state in SO₂ and +6 oxidation state SO₃. Whereas, O is present in 0 oxidation state in O₂ and -2 oxidation state in SO₃.

Therefore, SO₂ loses electrons and thus gets oxidized. Whereas, O₂ gains electrons and thus gets reduced.

In this reaction, SO₂ is the reducing agent and O₂ is the oxidizing agent.
