How many molecules are in 2.00 moles of h2o

Chemistry
1 answer:
Sedaia [141]3 years ago
8 0
1 mole = 6.022×10^23 atoms. 1 water molecule = 2 Hydrogen atoms + 1 oxygen atom. So, 1 mole H2O = 1.2044×10^24 hydrogen atoms. Therefore 2 mole H2O will have 2.4088×10^24 hydrogen atoms.

Anne is trying to attract her metal pencil box with a magnet from the other side
Dima020 [189]

Answer:

The pencil box is too far away from the magnet to make it move.

Explanation:

The most likely scenario here is that the pencil box is too far away from the magnet to make it move.

A magnet has a force field around it which dictates the region where magnetic influences can be felt when a magnetic body is brought near it.

Outside the force field, a magnet has no effect on a magnetic body.

  • Since the magnet is not attracting or repelling the metallic box of pencils, they most be located outside the field of force of the magnet.
  • When they are within the force field, repulsion or attraction occurs and the field draws the metal to itself or repel.

Objects that are far away from a magnetic source will feel no effect of the force field of a bar magnet.

Choose the correct statement regarding the relative size of atoms:
Sonbull [250]

Answer:

The atoms on left side are larger than the atoms on the right side of the periodic table because those on the right have more proton's.

Explanation:

As we travel along a period in a periodic table then the atomic radii decreases

This is because as we travel along a period we have that the atomic number of the atoms increases which means the the number of proton's increased

But the electron's add to the same outer shell throughout the period , which means the effective nuclear charge increases which pulls the outer electrons toward's the nucleus and the size decreases.

Therefore the atoms on left side are larger than the atoms on the right side of the periodic table because those on the right have more proton's.

How were atomic models developed when no one had seen an atom?
AnnyKZ [126]
Atomic models were developed through indirect observation even though no one had seen an atom. There were many experiments of which I know nothing about, but in the end the scientists managed to come up with a formula and various models to describe atoms.
