Moles of phosphorus pent-oxide :

$\frac{14.2 g}{284 g/mol}=0.05 mol$

According to reaction, 1 mole of phosphorus pent-oxide is obtained from 5 moles of oxygen gas.

Then 0.05 mole of phosphorus pent-oxide will be obtained from:

$\frac{5}{1}\times 0.05 mol=0.25 mol$

Hence,the correct answer is option e.

How many individual orbitals does carbon use for all of its electrons? Remember, there are two electrons in each filled orbital

Andreas93 [3]

Answer:

Three orbitals

Explanation:

The electronic configuration of carbon is given as follows;

1s²2s²2p²

Therefore, out of the six electrons of the carbon atoms, 4 fill the 1s and 2s orbitals with 2 electrons each, while the two remaining electrons are situated in the 2p orbital, with the electrons in the 2p orbital will remain unpaired such that they will have similar quantum numbers in accordance with Pauli exclusion principle.

The graph shows the reaction pathway for the reaction Q + R N + M. Interpret the graph by describing what each of the letters (A

Vladimir [108]

Answer: The reaction is exothermic reaction as the energy of products is less than the energy of reactants.

Explanation: Exothermic reactions are defined as the reactions in which energy of the product is less than the energy of the reactants. The total energy is released in the form of heat and $\Delta H$ for the reaction comes out to be negative.

Labeling of the parts in the diagram:

A represents the activation energy which is the energy required by reactants to cross the energy barrier to get converted to products.

E represents the potential energy of the reactants.

B represents the activated complex.

D represents the potential energy of the products.

C represents the total enthalpy change of the reaction, which comes out to be negative for exothermic reactions.

$\Delta H=E_P-E_R$
