How many moles of iron does 50.0 g of iron (Fe) represents?

Chemistry
1 answer:
mixer [17]3 years ago
7 0

0.9mole of Fe

Explanation:

Given parameters:

Mass of Fe = 50g

Unknown:

Number of moles of iron = ?

Solution:

The number of moles is the particle that contains the avogadro's number of particles.

It is a unit for reporting chemical measurement.

To find the number of moles of a substance;

 Number of moles = \frac{mass}{molar mass}

Molar mass of Fe= 56g/mol

 Number of moles = \frac{50}{56} = 0.9mole of Fe

Which of the following statements is always TRUE for the freezing of water?
Rom4ik [11]

ΔG > 0 is always true for the freezing of water.

Explanation:

  • The freezing of water is only spontaneous when the temperature is fairly small. Over 273 K, the higher value of TΔS causes the sign of ΔG to be positive, and there is no freezing point.
  • The entropy decreases as water freezes. This does not infringe the Thermodynamics second law. The second law doesn't suggest entropy will never diminish anywhere.
  • Entropy will decline elsewhere, provided it increases by at least as much elsewhere.

bazaltina [42]

The question is incomplete, the complete question is:

The element tin has the following number of electrons per shell: 2.8. 18, 18, 4. Notice that the number of electrons in the outer shell of a tin atom is the same as that for a carbon atom. Therefore, what must be true of tin? Tin is a polar atom and can bind to other polar atoms. Tin has a high molecular weight to give tin-containing molecules greater stabilty. All of the above Tin conform single covalent bonds with other elements, but not double or triple covalent bonds Tincan bind to up to four elements at a time

Answer:

Tin can bind to up to four elements at a time

Explanation:

Certain important points were made in the question about tin and one of them is that tin is an element in the same group as carbon hence it has the same number of valence electrons as carbon.

Carbon is always tetra valent. The tetra valency of carbon is the idea that carbon forms four bonds.

If tin has the same number of valence electrons as carbon, then, tin can bind to up to four elements at a time

What kind of properties can only be observed when a substance changes into a different substance?
Shkiper50 [21]
<h3>Answer:</h3><h2>Chemical properties</h2><h3>Explanation:</h3>

By its very definition, a chemical property is one which is exhibited as a result of a chemical reaction. This may happen during or after the reaction. This is because in a chemical reaction there is a transformation in the physical composition of the components and this directly affects its chemical properties.
