Pls solve it and show your work :((
lisabon 2012 [21]

Answer:

See below

Step-by-step explanation:

To graph the line we need two points, one point is the y-intercept, the second point to be calculated.

Q7

<u>y = -3x + 6</u>

  • The y-intercept is (0, 6)

<u>Let the domain be x = 5 for the second point, then:</u>

  • y = -3*5 + 6 = -15 + 6 = -9
  • The point is (5, -9)

Connect these points to get the graph

Q8

<u>y = 4/5x - 3</u>

  • The y-intercept is (0, -3)

<u>Let the domain be x = 5 for the second point, then:</u>

  • y = 4/5*5 - 3 = 4 - 3 = 1
  • The point is (5, 1)

Connect these two points to get the graph

Butyric acid ( c3h7cooh) is a weak acid . what is the ph of a 0.0250 m solution of this acid. ka = 1.5 x 10-5 (2 decimal places)
Wewaii [24]

The pH of the weak acid is 3.21

Butyric acid is known as a weak acid, we need the concentration of [H+] formula of weak acid which is given by this equation :

[H^{+}]=\sqrt{Ka . Ma}

where [H+] is the concentration of ion H+, Ka is the weak acid ionization constant, and Ma is the acid concentration.

Since we know the concentration of H+, the pH can be calculated by using

pH = -log[H+]

From question above, we know that :

Ma = 0.0250M

Ka = 1.5 x 10¯⁵

By using the equation, we can determine the concentration of [H+]

[H+] = √(Ka . Ma)

[H+] = √(1.5 x 10¯⁵ . 0.0250)

[H+] = 6.12 x 10¯⁴ M

Substituting the value of [H+] to get the pH

pH = -log[H+]

pH = -log(6.12 x 10¯⁴)

pH = 3.21

Hence, the pH of the weak acid c3h7cooh is 3.21
