Answer:

The mathematical equation, N = n × NA, can be used to find the number of atoms, ions or molecules in any amount (in moles) of atoms, ions or molecules: 10 moles of helium atoms = 10 × (6.022 × 1023) = 6.022 × 1024 helium atoms.

A compound is made up of only iron and oxygen. The ratio of iron ions to oxide ions is 2:3 in compound. The IUPAC name for this
Sergeu [11.5K]

Answer: iron (iii) oxide, Fe2O3.

Explanation: we must calculate the oxidation state of Fe in Fe2O3

Fe2O3 = 0

2Fe + 3(-2) = 0

2Fe — 6 = 0

2Fe = 6

Fe = 6 /2 = 3

So the oxidation state of Fe in Fe2O3 is +3

So the name of the compound is iron (iii) oxide

RUDIKE [14]

Answer:

The correct option is: A. H₂SO₄

Explanation:

Acid is a charged or a neutral molecule that is a proton donor and electron pair acceptors.

Acids can be classified into monoprotic acids and polyprotic acids.

Monoprotic acids are the acids that can release only one proton on dissociation.

Whereas, polyprotic acids are the acids that can release more than one proton on dissociation.

Diprotic acid is a type of polyprotic acid that can release two protons on dissociation. Example: H₂SO₄

S_A_V [24]

Answer:

Does the wave require a medium in order to travel?

Explanation:

The question whose answer would determine whether the wave in question is mechanical or electromagnetic would be <u>if the wave requires a medium in order to travel or otherwise.</u>

<em>A mechanical wave would require a medium in order to transport its energy from one place to another, that is, travel. On the other hand, an electromagnetic wave does not require any medium in order to travel, that is, it can travel through vacuums or empty spaces</em>. <u>Light</u> and <u>sound waves</u> are typical examples of <u>electromagnetic</u> and <u>mechanical waves</u> respectively.
