A 1.0 l buffer solution is 0.15 m in hcn and 0.10 m in nacn. which action will destroy the buffer?
rjkz [21]

The buffer will probably be destroyed by the addition of HCN.

<h3>What is buffer solution?</h3>

A weak acid and the conjugate base of the weak acid, or a weak base and the conjugate acid of the weak base, are combined to form the buffer solution, a water-based solvent solution. They withstand being diluted or having modest amounts of acid or alkali added to them without changing their pH.

Given that a 1.0 l buffer solution is 0.15 m in HCN and 0.10 m in NaCN.

We need to find a action which one destroy the buffer solution.

A buffer is a substance made of salt and a weak acid that is beneficial. From the aforementioned chemicals, HCN is a potent acid and NaCN is a salt between HF and NaCN. Therefore, the buffer will probably be destroyed by the addition of HCN.

Hot air balloons generally descend at the rate of 200 to 400 ft./min. Six balloons to send 245 ft./min. For four minutes find th
Alenkinab [10]

Answer:

1,715 feets

Step-by-step explanation:

Give the following :

General descent rate of hot air balloon = 200 - 400ft/min

Six balloons descend at a rate of 245 ft/min for four minutes

The total change in altitude for all six balloons :

From speed = distance / time

Speed = 245 ft / min ; time = 7 minutes

Hence distance descended by the six balloons :

245 ft/min × 7 minutes = 1,715 fts

Hence total change in altitude = 1,715 feets
