6 0
Among BF₃, NF₃, OH⁻ and ALCl₃ both NF₃ and OH⁻ acts as a lewis base.

Explaination:
According to lewis theory of acid and base, base is a specie which has either lone pair of electrons or is negatively charged. So, in the given compounds Nitrogen trifluoride contain lone pair of electron on nitrogen and Hydroxide contains a negative charge on oxygen. And botha are capable to donate these electrons to a lewis acid (electrophiles).

What is the usual composition of acid etch?
Ratling [72]

Answer:

Explanation:acid etching  

etching

the cutting of a hard surface such as metal or glass by a corrosive chemical, usually an acid, in order to create a design.

etching  - etching of dental enamel with an acid in order to roughen the surface, increase retention of resin sealant, and promote mechanical retention.

acid etching

microscopic roughening of dental enamel with an acid (usually phosphoric acid) to remove the smear layer and open enamel tubules, increase retention of resin sealant, and promote mechanical retention.

acid etching Dentistry

The application of a weak acid—e.g., 30% phosphoric acid—to the surface of enamel to roughen the surface of a tooth before bonding a resin or veneer; acid etching increases mechanical retention, cleans the enamel and improves the wetting of resins. See Cosmetic dentistry.

How many moles of ammonium nitrate are there in 32.5 mL of<br> a0.125 M NH4NO3 solution?
Nady [450]

<u>Answer:</u> The number of moles of ammonium nitrate is 0.004 moles.

<u>Explanation:</u>

To calculate the number of moles for given molarity, we use the equation:

\text{Molarity of the solution}=\frac{\text{Moles of solute}\times 1000}{\text{Volume of solution (in mL)}}

We are given:

Molarity of NH_4NO_3 solution = 0.125 M

Volume of solution = 32.5 mL

Putting values in above equation, we get:

0.125M=\frac{\text{Moles of }NH_4NO_3\times 1000}{32.5mL}\\\\\text{Moles of }NH_4NO_3=0.004mol

Hence, the number of moles of ammonium nitrate is 0.004 moles.
