What is the electron configuration for<br> 08<br> 16

Elis [28]

The electron configuration for Oxygen : [He] 2s²2p⁴

<h3>Further explanation</h3>

Writing electron configurations starts from the lowest to the highest sub-shell energy level. There are 4 sub-shells in the shell of an atom, namely s, p, d, and f. The maximum number of electrons for each sub-shell is

• s: 2 electrons

• p: 6 electrons

• d: 10 electrons and

• f: 14 electrons

Charging electrons in the sub-shell uses the following sequence:

The element is Oxgen, with symbol O, and :

the atomic number=8=number of electron

the atomic mass=16

The electron configuration based on the number of electrons(for Oxygen=8), so the configuration :

$\tt _8^{16}O:1s^22s^22p^4$ or we can write with noble gas [He] 2s²2p⁴

Para la siguiente reacción química demuestre que cumple con la Ley de la Conservación de la Materia. Recuerde que debe justifica

nikklg [1K]

Answer:

In this chemical reaction, which is considered irreversible, that is why the reaction arrow is ONE and unidirectional and not two in opposite directions, which means reversibility of the reaction.

In summary, if we look closely at the reaction, we observe that the stoichiometric values are balanced in the reaction, therefore there is THE SAME AMOUNT OF REAGENTS AS PRODUCTS.

This phenomenon has to be met in ALL CHEMICAL REACTIONS, the stoichiometric balance is essential for this reaction to be well expressed.

Why is stoichiometric balance so important? Why we indicate that we have the same amount of reagents as products, means that NOTHING IS LOST, EVERYTHING IS TRANSFORMED in the matter of the organic compounds that reacted.

Explanation:

Although if we observe the stoichiometric values well they are not correct with respect to oxygen, therefore it would be necessary to correct that in the chemical reaction, but above we briefly explain why the balancing of the reactions and the relationship they have with the conservation of the mass.

The law of conservation of mass indicates that mass is never lost, but is transformed, like energy, considering that it happens in terrestrial life.

what is the limiting reactant when 1.50g of lithium and 1.50 g of nitrogen combine to form lithium nitride, a component of advan

PSYCHO15rus [73]

<h3>Answer:</h3>

Limiting reactant is Lithium

<h3>Explanation:</h3>

<u>We are given;</u>

Mass of Lithium as 1.50 g
Mass of nitrogen is 1.50 g

We are required to determine the rate limiting reagent.

First, we write the balanced equation for the reaction

6Li(s) + N₂(g) → 2Li₃N

From the equation, 6 moles of Lithium reacts with 1 mole of nitrogen.

Second, we determine moles of Lithium and nitrogen given.

Moles = Mass ÷ Molar mass

Moles of Lithium

Molar mass of Li = 6.941 g/mol

Moles of Li = 1.50 g ÷ 6.941 g/mol

= 0.216 moles

Moles of nitrogen gas

Molar mass of Nitrogen gas is 28.0 g/mol

Moles of nitrogen gas = 1.50 g ÷ 28.0 g/mol

= 0.054 moles

According to the equation, 6 moles of Lithium reacts with 1 mole of nitrogen.
Therefore, 0.216 moles of lithium will require 0.036 moles (0.216 moles ÷6) of nitrogen gas.
On the other hand, 0.054 moles of nitrogen, would require 0.324 moles of Lithium.

Thus, Lithium is the limiting reagent while nitrogen is in excess.

What are the steps to Photosynthesis

prohojiy [21]

Answer:

Step 1-Light Dependent. CO2 and H2O enter the leaf.

Step 2- Light Dependent. Light hits the pigment in the membrane of a thylakoid, splitting the H2O into O2.
