Answer:

<h3>An acid that contains more than one ionizable proton is a polyprotic acid. The protons of these acids ionize in steps. The differences in the acid ionization constants for the successive ionizations of the protons in a polyprotic acid usually vary by roughly five orders of magnitude.</h3>

The graph of y=f(x) is shown above. Which of the following could be the graph of y=f′′(x)?.
AfilCa [17]

The true statement about the graph of f(x) is f(x) = \frac 35x + 3

The graph of f(x) is a straight line that passes through the points (-5,0) and (0,3).

Start by calculating the slope (m)

m = \frac{y_2 - y_1}{x_2 -x_1}

So, we have:

m = \frac{3-0}{0--5}

Simplify

m = \frac{3}{5}

The equation of the line is then calculated as:

y = m(x -x_1) + y_1

This gives

y = \frac 35(x -0) + 3

Open bracket

y = \frac 35x + 3

Express y as a function of x

f(x) = \frac 35x + 3

Hence, the true statement about the graph of f(x) is f(x) = \frac 35x + 3

If a person takes 30 ml of vinegar a day and the molarity of the vinegar is 0. 84 m then how many grams of acetic acid (hc2h3o2
babunello [35]

The mass of the acetic acid is 1.512 g.

<h3 /><h3>What is Molarity?</h3>

molarity is the concentration of a substance in mol per dm³

From the question,

The number of moles contained in the 30 mL vinegar is

  • n = (0.84×30)/1000
  • n = 0.0252 mol.

the molar mass of vinegar is calculated below.

  • m.m of (HC₂H₃O₂) = [1+(12×2)+(1×3)+(16×2)]
  • m.m = (1+24+3+32]
  • m.m = 60 g/mol.

To calculate the mass of acetic acid, we use the formula below.

  • R.m = n×m.m............. Equation 1

Where

  • R.m = mass of acetic acid.

Substitute these values into equation 1

  • R.m = (0.0252×60)
  • R.m = 1.512 g.

Hence, The mass of the acetic acid is 1.512 g.
