Chemistry
1 answer:
Ainat [17]3 years ago
5 0

Answer:

Adding Neutrons

General Formulas and Concepts:

<u>Chemistry - Atomic Structure</u>

  • Atoms Composition
  • Nucleus - Protons, Neutrons
  • Electrons

Explanation:

We know that adding Protons to any atom will change its chemical properties and make it a different element.

We also know that adding Electrons to any atom will simply only change its overall charge.

Isotopes are formed by adding <em>neutrons</em> to the nucleus. It will be the same element but it would have a different mass and amount of neutrons.

eduard

Answer:

The correct answer is 169.56 g/mol.

Explanation:

Based on the given information, the mass of Ag deposited is 1.24 g, and the mass of unknown metal X deposited in another cell is 0.650 g. The number of moles of electrons can be determined as,

= 1.24 g Ag * 1mol Ag/107.87 g/mol Ag * 1 mol electron/1 mol Ag ( the molecular mass of Ag is 107.87 g/mol)

= 0.0115 mole of electron

The half cell reaction for the metal X is,  

X^3+ (aq) + 3e- = X (s)

From the reaction, it came out that 3 faraday will reduce one mole of X^3+.  

The molar mass of X will be,  

= 0.650 g/0.0115 *3 mol electron/1 mol

= 56.52 * 3

= 169.56 g/mol

Jasper made a list of the properties of electromagnetic waves. Identify the mistake in the list.
ch4aika [34]

Answer:

B. Line 2 has a mistake

Explanation:

1. All electromagnetic waves are made of both electric and magnetic fields (hence the name electromagnetic).

2. All electromagnetic waves are transverse, and not longitudinal.

3. All electromagnetic waves can travel through space because they do not need particles to travel (like sound waves).

4. Electromagnetic waves all travel at the speed of light (299 792 458 m/s).
