Ka is the acid-dissociation constant of each of these acids. It represents the proportion of a given amount of the acid that dissociates from the acid into H+ and it’s conjugate base when dissolved into solution.

The concentration of H+ determines the strength of the acids, so those acids with the biggest Ka values are the strongest acids.

Your order would be:
Aspirin (strongest)
Benzoic
Hydrocyanic (weakest)

a sample of 25.0g of an unknown metal is added to 25.0ml of water in a graduated cylinder and the final volume is 28.5ml what is
leva [86]

Answer:

<h2>The answer is 7.14 g/mL</h2>

Explanation:

The density of a substance can be found by using the formula

density =  \frac{mass}{volume}  \\

From the question

mass of metal = 25 g

volume = final volume of water - initial volume of water

volume = 28.5 - 25 = 3.5 mL

It's density is

density =  \frac{25}{3.5}  \\  = 7.142857...

We have the final answer as

<h3>7.14 g/mL</h3>

Hope this helps you

Joseph drives 25miles North in 15 minutes then he drives 40 miles east in 30 minutes, then he uses cruise control option for 1 h
Musya8 [376]

Answer: 1.25 miles per minute

Explanation:

Average speed is the rate of change of total distance covered per unit time.

i.e Average speed = (Total distance / Time taken)

Total distance covered = (25miles + 40 miles + 70 miles + 15 miles)

= 150 miles

Total time taken = ( 15 minutes + 30 minutes + 1 hour + 15 minutes) = 120 minutes

Since 60 minutes = 1 hour, the total time taken is 120 minutes

Now, apply Average speed = (Total distance / Time taken)

= (150 miles / 120 minutes)

= 1.25 miles per minutes

Thus, Joseph drove with an average speed of 1.25 miles per minute.
