Give an example of a state function and explain why it is a state function

inessss [21]

A specific state which is defined being a property without the path taken to achieve that state based on it, is understood as a state function.
While the functions whose value is based on the direction taken among two states are named direction or path functions, on the other hand.
The system's thermodynamic condition relates to the current material in temperature, pressure and quantity.
State functions rely only on certain requirements and not on how they have been achieved. State functions for an instance, involve entropy, density, enthalpy and internal energy.
They are known as state functions as they quantitatively define a thermodynamic system's equilibrium condition, regardless of how the system landed in that condition.

Consider the cell notation Cd(s) | Cd(NO3)2(aq) || AgNO3(aq) | Ag(s) with standard reduction potentials for Cd2+ and Ag+ as -0.4

The value of the Gibbs free energy shows us that the reaction is spontaneous.

<h3>What is the Gibbs free energy?</h3>

The Gibbs free energy is a quantity that helps us to be able to determine the spontaneity of a reaction.

In order to obtain the Gibbs free energy, we must obtain the Ecell as follows; 0.799V - (-0.402V) = 1.201 V

Now;

△G = -nFEcell

△G = -(2 * 96500 * 1.201)

△G = -232kJ/mol

Ammonia chemically reacts with oxygen gas to produce nitric oxide and water . What mass of ammonia is consumed by the reaction o

prohojiy [21]

The chemical equation represents the reaction describes is;
4NH3 + 5O2 = 4NO + 6H2O

Therefore 4 moles of NH3 reacts with 5 moles of O2.
1 mole of O2 (molar mass) = 2 * 16 = 32g.
5 moles of O2 = 5 * 32 = 160g
4 moles of NH3 = 4 (14 + 3*1) = 68g

Therefore, 68g of NH3 reacts with 160g of O2.
But, we have only 4.5 g of oxygen.
68g reacts with 160g
Xg reacts with 4.5
X = 68*4.5 / 160 = 1.9125g

Which contains more carbon 4.71 g of C6H12O6 or 5.85 g C2H6O?

maksim [4K]

Answer:

5.85 g C2H6O has more carbon

Explanation:

Weight of carbon in 4.71 g of C6H12O6

$4.71 * 12.01\\56.5671\\$ grams

Weight of carbon in 5.85 g of C2H6O

$5.85 * 12.01\\70.259\\$ grams

Hence, 5.85 g C2H6O has more carbon

The spontaneous intermingling of atoms among different substances is accomplished by_____. active transport energy combustion di

elixir [45]

Answer- The intermingling of atoms takes place the help of diffusion.

Explanation- There are two areas one has a higher concentration and the other has a lower concentration and a substance moves from higher to lower and the process happening is called diffusion.

Combustion is heating up of the substance hence does not have any intermingling atoms and energy transport also does not have any atoms mingling together hence diffusion is the correct option.
