Identify the lewis base in this balanced equation: fe3+ h2o fe(h2o)63+

H20

Explanation:

because it is the base that contributes electrons

Answer : The Lewis-base in this reaction is, water

Explanation :

According to the Lewis acid-base theory,

Lewis acid : It is a substance that can accepts pairs of electrons to form a covalent bond.

Lewis-base : It is a substance that can donates pairs of electrons to form a covalent bond.

The given balanced equation is:

In this reaction, ion is Lewis-acid and is a Lewis-base. The donates electrons to ion to form .

Hence, the Lewis-base in this reaction is, water

out of these options:

ability to burn paper

pure sodium reacting violently with water

the boiling point of water

helium does not tend to react with anything

i would say this is a physical property:

helium does not tend to react with anything

why? :

i said helium does not tend to react with anything because well, it reacts to ! but ability to burn paper, pure sodium reacting violently with water, & the boiling point of water are chemical or

physical properties: the properties of a substance that can be observed without changing the chemical makeup of the substance

chemical properties: properties of a substance relating to the chemical nature and reactivity of the substance
