i dont understand this i cant think :These ions have the same stable electron configuration as the noble gas helium. All Group 1

atoms can lose one electron to form positively charged ions. ... Elements in Groups 15,16 and 17, find it easier to gain electrons than lose them.

Answer:

Li atoms readily give up one electron to form positively charged, Li+ ions. These ions have the same stable electron configuration as the noble gas helium. All Group 1 atoms can lose one electron to form positively charged ions.

Explanation:

I DON'T KNOW IF THIS IS THE RIGHT ANSWER BUT I'M TRYING TO JUST ANSWER.

Answer:

Explanation:

-We know that an atom is table if they have 8 valence electrons (like noble gases, they are stable)

-Group 1 atoms only has 1 valence electron, in order to become stable, they are desperately wanted to lose that one valence electron to become stable.

-While group 15 has 5 electrons, it is easier for them to gain 3 electrons to become 8 electrons than losing all 5 electrons.

-the same thing for group 16 has 6 valence electrons and 17 has 7 electrons. It is easier for them to gain 2 and 1 more valence electrons to become stable.

Hope this helps!

Ammonia is oxidized with air to form nitric oxide in the first step of the production of nitric acid. Two principal gas-phase re
nevsk [136]

Answer:

4NH₃(g)  + 5O₂(g)  →  4NO(g)  +  6H₂O

2NO(g) + O₂(g) → 2 NO₂

Explanation:

First of all, we need to consider the reaction for production of ammonia. In this reaction we have as reactants, nitrogen and hydroge.

3H₂ (g) +  N₂(g)  →  2NH₃ (g)

Afterwards, ammonia reacts to oxygen, to produce NO and H₂O

The equation for the process will be:

4NH₃(g)  + 5O₂(g)  →  4NO(g)  +  6H₂O

Then, we take the nitric oxide to make it react, to produce NO₂, in order to produce nitric acid, for the final reaction:

2NO(g) + O₂(g) → 2 NO₂

3NO₂(g) + H₂O(g) → 2 HNO₃ (g) + NO(g)

What is the reactant(s) in the chemical equation below?
butalik [34]

Answer:

C. 3CO(g) + Fe2O3(s)

Explanation:

The substance(s) to the hath left of the arrow in a chemical equation art hath called reactants.  A reactant is a substance yond is presenteth at the starteth of a chemical reaction.  The substance(s) to the right of the arrow art hath called products.  A product is a substance yond is presenteth at the endeth of a chemical reaction

So in this example, 3CO(g) + Fe2O3(s) art the reactants.

The 2Fe(S) + 3CO2(G) art the products.

Desire I holp! Has't a most wondrous day!

Hope I helped!  Have a great day!

Consider the three equations below.
mash [69]

Answer:

Nuclear fusion plays an important role in making elements that are heavier than helium.

Explanation:

Nucleosynthesis is the process by which new atomic nuclei are created from pre-existing nucleons (protons and neutrons) and nuclei. According to current theories, the first nuclei were formed a few minutes after the Big Bang, through nuclear reactions in a process called Big Bang nucleosynthesis.

In order to synthesize a new element, there must be a change in the number of protons. We should remember that elements are known by the number of their protons as it represents their atomic number.

Elements heavier than helium are formed by nuclear nucleosynthesis in which nuclear fusion plays a very crucial role as typified by the equations shown in the question.
