m = mass of the particle = 2 x 10⁻³⁰ kg
Δv = uncertainty in velocity of the particle = 10² m/s
Δx = uncertainty in position of the particle = ?
h = plank's constant = 6.63 x 10⁻³⁴ J-s
uncertainty principle is given as
m Δx Δv ≥ h/(4π)
inserting the values
(2 x 10⁻³⁰) Δx (10²) ≥ (6.63 x 10⁻³⁴)/(4(3.14))
Δx ≥ 2.64 x 10⁻⁷ m
so minimum possible uncertainty is 2.64 x 10⁻⁷ m

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.

Answer:
Explanation:
Hello!
In this case, since the percent water is computed by dividing the amount of water by the total mass of the hydrate; we infer we first need the molar mass of water and that of the hydrate as shown below:
Thus, the percent water is:
So we plug in to obtain:
Best regards!
