Which acid/base pair will give an equivalence point that cannot be predicted solely by a general knowledge of acid and base stre
sleet_krkn [62]

The acid/base pair that give equivalence point that Cannot be predicted by general knowledge is NaOH and HCI ONH.

<h3>What is an Acid and base?</h3>

An Acid is a substances that is corrosive in nature and turn blue lithmus paper to red which it react with base to produce salt and water.

Acid dissolve metals.

Base is a substance that turn red lihthmus paper to blue and react with acid to produce salt and water.

Therefore, The acid/base pair that give equivalence point that Cannot be predicted by general knowledge is NaOH and HCI ONH.

In order to calculate how many neutrons are in an atom, you must subtract the mass number from the number of protons? Neutrons =
Inessa05 [86]

Answer:

True.

Explanation:

The mass number of an atom can be calculated using no of protons and the no of neutrons.

Mass number = no of protons + no of neutrons

We can rearrange the above formula to find the no of neutrons as follows :

no of neutrons = Mass number - no of protons

or

Neutrons = Mass - protons.

Hence, the given statement is true.

What’s the answer I don’t know how to do it
Inessa05 [86]

Answer:

3.63m/s²

Explanation:

Given parameters:

Mass of box  = 8kg

Net force  = 29N

Unknown:

Acceleration of the box = ?

Solution:

To solve this problem, we use Newton's second law of motion which is stated as;

       Force  = mass x acceleration

 Acceleration  = \frac{Force }{mass}   = \frac{29}{8}  

Acceleration  = 3.63m/s²
