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.

To the nearest tenth of a precent, 78 is what precent of 82
forsale [732]

Answer:

95.1

Step-By-Step Explanation

78:82*100 =

(78*100):82 =

7800:82 = 95.12

Now we have: 78 is what percent of 82 = 95.12

Question: 78 is what percent of 82?

Percentage solution with steps:

Step 1: We make the assumption that 82 is 100% since it is our output value.

Step 2: We next represent the value we seek with x.

Step 3: From step 1, it follows that 100%=82

Step 4: In the same vein, x%=78

Step 5: This gives us a pair of simple equations:

$100\%=82(1)

$x\%=78(2)

Step 6: By simply dividing equation 1 by equation 2 and taking note of the fact that both the LHS

(left hand side) of both equations have the same unit (%); we have

100% over x% = 82 over 78

Step 7: Taking the inverse (or reciprocal) of both sides yield

x% over 100% = 78 over 82

x = 95.12%

Therefore, 78 is 95.12% of 82

3.Tracie set out from Elmhurst, IL to go to Franklin Park. On the way, she made a few stops to do errands. Each stop is indicate
fenix001 [56]

The total distance Tracy traveled was 15,000 feet assuming each unit represents 1,000 feet.

<h3>How to calculate the total distance?</h3>

The total distance is the sum of all the distance between stops.

Partial distances:

  • Home to stop 1: 2,000 feet
  • Stop 1 to 2: 4,000 feet
  • Stop 2 to 3: 5,000 feet
  • Stop 3 to 4: 4,000 feet
  • Total distance: 15,000 feet

However, the real distance would be 10.63 units based on the locations in the grid.

  • d=√(0−8)^2+(7−0)^2
  • d=√8^2+7^2
  • d=√64+49
  • d=√113 =10.63 units
