Cations are formed by losing electrons in the valence shell of atoms. There are more protons than electron ions making the atom more positive.

An anion has <em><u>gained electrons</u></em> and therefore has more electrons than protons. It has a negative charge.


An example if this doesn't make too much sense.

Charged Atoms: If electrons are removed from an atom, that atom becomes positively charged because it has more positive charge carriers (protons) than negative charge carriers (electrons)

These types of charged atoms are called positive ions or, cations. DEPENDING ON THE CIRCUMSTANCES, the removed electrons can remain free or they may attach themselves to another atom that can accept extra electrons. If this occurs, a negatively charged ion, or anion, is created.


I hope I made this clear enough for anyone who needed help on this. Hope this helps!!! Have a great day :)))

In a sample of H2SO4 containing 200 sulfur (S) atoms, how many atoms of hydrogen (H) would there be?
Otrada [13]

In a sample of H2SO4 that contain 200 S atom the number of hydrogen atoms  would be 400  atoms

explanation

there are two moles of H2  in H2SO4 therefore by use of ratio between S:H2 which is 1:2 atoms therefore the atoms of hydrogen = 2 x200 = 400 atoms

Determine the energy released per kilogram of fuel used. given mev per reaction, calculate energy in joules per kilogram of reac
tatuchka [14]

The energy released in nuclear reactions are far larger than that released in chemical reactions due to the release of nuclear energy from the nucleus.

<h3>Why is the energy released in a reaction?</h3>

Energy is released in a reaction due to the breaking of bonds are well as formation of bonds.

The quantity of energy released in reactions differs according to the reaction type involved.

When compared to chemical reactions, the energy released in nuclear reactions are very much higher because of the changes that occurs in the nucleus of the atoms involving nuclear energy.

The energy, E released in nuclear reactions is given by the formula below:

E = mc^{2}

where m is the mass of the substance and c is the speed of light.

Therefore, the energy released in nuclear reactions are far larger than that released in chemical reactions.

What is the mass of a 1.68-l sample of a liquid that has a density of 0.921g/ml?
Gwar [14]
Hey there!

Volume in mL :

1.68 L  * 1000 => 1680 mL

Density = 0.921 g/mL

Therefore:

Mass = density * Volume

Mass = 0.921 * 1680

Mass = 1547.28 g
