How do the ionic radii vary within a group of non-metals?

Chemistry
1 answer:
stellarik [79]3 years ago
8 0

Answer: Ionic radii is half the distance between two ions.

Explanation: from top to bottom down an element group, ionic radius increases. This is because a new electron shell is added as you move down the periodic table.

A cube with sides 3cm.Its mass is 54g. will it sink or float
zloy xaker [14]

Answer:

It will sink.

Explanation:

Density of water=1gm/cc (In CGS)

Volume of cube=l^3 =3^3= 27cc

Mass of cube =54gm

Density of cube=M/V =54/27 =2gm/cc

Here, density of cube is greater than that of water. So, the cube sinks.

Explain why doesn’t the total pressure increase when more gas is added to the chamber?
german

Pressure is inversely proportional to volume. Therefore, the effect of pressure change is opposite to the effect of volume change. So when more gas is added to the chamber the total pressure of the chamber doesn't increase.

<h3>What are the different relations between pressure and volume?</h3>
  • As the volume changes, the concentrations and partial pressures of both reactants and products change.
  • As the volume decreases, the reaction shifts to the reaction side with fewer gas particles.
  • As the volume increases, the reaction shifts to the side of the reaction containing more gas particles.
  • As the pressure increases, the equilibrium shifts towards reactions with fewer moles of gas.
  • As the pressure decreases, the equilibrium shifts to the side of the reaction with higher moles of gas.
  • Moreover, the pressure change in the system due to the addition of the inert gas is not limited to this.

Water (h2o) is composed of the same elements as hydrogen peroxide (h2o2). Why do these substances have different properties?
insens350 [35]
The reason for this is because hydrogen peroxide has an extra oxygen atom, While both substances are made of hydrogen and oxygen, water has 2 hydrogen atoms and one oxygen, while hydrogen peroxide has 2 hydrogens and 2 oxygens.
