What is the difference between a cesium atom (Cs) and a cesium ion (Cs+1)?

Chemistry

ELEN [110]3 years ago
5 0

Answer:

The difference between a cesium atom (Cs) and a cesium ion (Cs+1) is of 1 electron.

Explanation:

Cesium is an S-block element placed in 1st group and 6th period of modern periodic table.The atomic number of Cs is 55. It has only one valence electron, when we remove that valence electron from Cs atom it becomes Cs+ ion. After removal of valence electron the number of protons and neutrons do not get affected. But the size of Cs+ ion becomes shorter than Cs atom.

consider this reaction at equilibrium at a total pressure: 2h2o(g) o2(g) 2h2o2(g) suppose the volume of this system is twice its
Daniel [21]

The total pressure when the new equilibrium is stabilized is half of the initial pressure of the system.

The given chemical reaction at a stable equilibrium is,

2H₂O(g)+O₂(g) = 2H₂O₂(g)

According to the ideal gas equation,

PV = nRT

P is pressure,

V is volume,

n is moles

R is gas constant,

T is temperature.

Assuming the temperature is constant.

If the volume of the system is twice the initial volume then the total pressure at the new equilibrium can be found out as,

P₁V₁ = P₂V₂

Where, P₁ and V₁ are initial volume and pressure while P₂ and V₂ are final pressure and volume.

If V₂ = 2V₁,

P₂ = P₁/2

So, the final total pressure will be half of the initial pressure.

kondor19780726 [428]

Answer:

b. transfer of electron(s).

Explanation:

An oxidation-reduction also called a redox reaction is a

chemical reaction in which electrons are transferred of between two species of reactants. It is a chemical reaction where the oxidation number of an atom, ion, or molecule, increases or decreases by losing or gaining electrons

Calculate the amount of oxygen gas collected by the displacement of water at 14◦C if the atmospheric pressure is 790 Torr and th
zhannawk [14.2K]

Answer : The amount of oxygen gas collected are, 0.217 mol

Explanation :

Using ideal gas equation :

PV=nRT

where,

P = pressure of gas = (790-12)torr=778torr=1.02atm     (1 atm = 760 torr)

V = volume of gas = 5 L

T = temperature of gas = 14^oC=273+14=287K

n = number of moles of gas = ?

R = gas constant  = 0.0821 L.atm/mol.K

Now put all the given values in the ideal gas equation, we get:

(1.02atm)\times (5L)=n\times (0.0821L.atm/mol.K)\times (287K)

n=0.217mole

Thus, the amount of oxygen gas collected are, 0.217 mol

Determine the volume of 3.30 mol of a gas at 25°C and 0.995 atm.
Alexxx [7]

Answer:

V = 81.14 L

Explanation:

Given data:

Volume of gas = ?

Number of moles = 3.30 mol

Temperature of gas = 25°C

Pressure of gas = 0.995 atm

Solution:

The given problem will be solve by using general gas equation,

PV = nRT

P= Pressure

V = volume

n = number of moles

R = general gas constant = 0.0821 atm.L/ mol.K

T = temperature in kelvin

Now we will convert the temperature.

25+273 = 298 K

now we will put the values in formula:

V = 3.30 mol 0.0821 atm.L/ mol.K   298 K / 0.995 atm

V = 80.74 L. atm / 0.995 atm

V = 81.14 L
