What of the following could be classified as matter

Answer:

The reaction of an aqueous hydrochloric acid solution with an aqueous sodium hydroxide solution is represented by the neutralization chemical equation:

HCl(aq) + NaOH(aq) --> NaCl(aq) + H2O(l) + Energy

Explanation:

This is called a neutralization reaction, which is a reaction in which an acid and a base react to form water and a salt. This reaction involves the combination of H+ ions and OH- ions to generate water. pH equal to 7 is a neutralization of a strong acid and strong base. The neutralization of a strong acid and weak base will have a pH of less than 7, and conversely, the resulting pH when a strong base neutralizes a weak acid will be greater than 7.

When a solution is neutralized, it means that salts are formed from equal weights of acid and base. The amount of acid needed is the amount that would give one mole of protons (H+) and the amount of base needed is the amount that would give one mole of (OH-).

The production of sodium chloride and water is the indication that reaction took place.

• The formation of sodium chloride and water would be evidence that a chemical reaction took place because new substances are formed from the reaction hydrochloric acid (HCl) and sodium hydroxide (NaOH).
• When  hydrochloric acid (HCl) reacts with sodium hydroxide (NaOH), the sodium of NaOH combine with chlorine of HCl produces sodium chloride (NaCl).
• Whereas the hydrogen of HCl combine with hydroxide of NaOH so we can conclude that production of sodium chloride and water is the indication that reaction took place.

Hello, Ginamuhs2!

The oxidizing agent in 2H2S + 3O2 → 2SO2 + 2H2O is the oxygen.

I hope this helps;)

Answer: Option (d) is the correct answer.

Explanation:

When two atoms are bonded together then it is known as a diatomic molecule.

Such as nitrogen exists as molecule in atmosphere so, it is a diatomic molecule.

Hydrogen also exists as molecule in atmosphere so, it is also a diatomic molecule. Also, bromine is a diatomic molecule because it exists as molecule into the atmosphere.

But helium exists as He molecule as it has 2 electrons so, as per the octet rule it's s-shell is completely filled. Hence, it is stable and exists as a monoatomic molecule into the atmosphere.

Thus, we can conclude that out of the given options, helium is not a diatomic molecule.

Answer:

HELIUM

That's your answer!!
