How many moles of oxygen molecules are present in 112ml of co2 at NTP?​

Chemistry

In each mole of carbon dioxide there will be one mole of O₂.

Let us calculate the moles of carbon dioxide gas present first

The conditions are NTP it means , Temperature = 293 K and P = 1 atm

We will use ideal gas equation

PV= nRT

Where

P = Pressure of gas = 1 atm

V= 112mL=0.112L

R= gas constant =0.0821 L atm /mol K

n = moles = ?

Putting values

moles=\frac{PV}{RT}=\frac{1X0.112}{0.0821X293}

moles = 0.00466

Thus moles of carbon dioxide will be 0.00466

The moles of O₂ = 0.00466

The atoms of a solid aluminum can are close together, vibrating in a rigid structure. If the can is warmed up on a hot plate, wh
Oksana_A [137]

Explanation:

Since atoms of solid aluminium can are closer to each other, therefore, when heat is supplied then transfer of energy in the form of heat will be faster.

As a result, when can is warmed up then atoms of solid aluminium can will start to vibrate more because heat will decrease the force of attraction between the molecules.

Thus, atoms will start to move away from each other and hence, they will vibrate more.

Why does ΔG for a reaction scale with reaction quantity but E does not? For example, ΔG0 rxn for the combustion of 1 mol of hydr
wariber [46]

Answer:

This is as a result of their property type

ΔG is extensive and E is Intensive. The explanation is as given below

Explanation:

Basically both ΔG and the cell potential or the electromotive force (E.M.F) has some disparity especially in their spontaneity, for spontaneous reaction ΔG = -ve while E = +ve and vice versa. But the most important disparity is their state function i.e one is intensive and the other is extensive property.

ΔG is an example of an extensive property, they are properties whose value is dependent on the volume or the size of the system. other examples are mass, volume etc.

E on the other hand is an intensive property, they are properties whose value is not dependent on the size of the system. As such, this differences explains why ΔG for a reaction scale with a reaction quantity and E does not.
