Answer:
If you want me to solve for b then
b ≤ −
6
Answer:
x = -3
Step-by-step explanation:
Add 2/3 x to both sides:
Subtract 8 from both sides:
Multiply both sides by 3:
Divide both sides by 11:
Therefore, point of intersection between both lines is at point (-3, -1)
D.
you cannot have a negative amount of rainfall, so the predicted value of -32.4cm doesn't make sense.
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 :
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
