6
Step-by-step explanation:
It's shifted two units to he left because: y=(x-h) means that the graph is shifted h units to the right and when the sign is positive you know that h is negative (subtracting a negative number is the same as adding the absolute value of that number )
Answer:
The answer is option 3.
Step-by-step explanation:
You have to substitute H+=2×10^(-9) into the equation of pH :
pH = -log[H+]
H+ = 2×10^(-9)
pH = -log[2×10^-9]
= 8.70 (3s.f)
C is the value of x to find it u use the equation 3x=338 and solve
