if eqaul volumes of 0.1 m naoh and 0.1 m hcl arw mixed, the resulting solution will contain a salt and what

Answers

Answer 1

Answer: It will contain NaCl. The acid base reaction will look like this: HCl(aq)+NaOH(aq)⇒H₂O(l)+NaCl(aq)

The reaction occurs due to the fact that HCl (being a strong acid) will dissociate into H⁺ and Cl⁻ while NaOH (being a strong base) will dissociate into OH⁻ and Na⁺. The H⁺ and OH⁻ will react together to form water and the Na⁺ and Cl⁻ will remain in solution as the salt. (this is sometimes called a neutralization reaction since the HCl and NaOH neutralize each other.)

I hope this helps. Let me know if anything is unclear.

Which element has the greatest electronegativity? fluorine chlorine bromine iodine

Answers

Answer: Option (a) is the correct answer.

Explanation:

It is known that for non-metals, on moving down a group there will be decrease in electronegativity of elements.

Smaller is the size of a non-metal, more easily an electron will be attracted by its nucleus. Whereas larger is the size of element more is the number of electrons present in the atom.

Hence, more will be the number of shells and attraction between the nucleus and outermost electrons will decrease. As a result, an electron will not easily get attracted by a larger atom.

Thus we can conclude that fluorine is the element that has the greatest electronegativity.

Fluorine has the greatest electronegativity

What is the reaction when magnesium becomes magnesium oxide

Answers

Magnesium and oxygen reacting to form magnesium oxide is a synthesis reaction. This reaction occurs when many reactants proceeds to reaction forming a single product. Synthesis reactions release energy in the form of light or heat, therefore they are exothermic reaction.
