Answer:
the mean is 6 but you don't have that as an option.
Explanation:
the mean is the average.
to find the mean you have to add all of your data first
3 + 2 + 2 + 12 + 6 + 5 + 14 + 4 = 48
then you have to divide your answer by how many numbers there are in total.
48 / 8 = 6
the mean is 6.

Explanation:
Refer to the Chemical Compounds table above. How many total elements are in
Ethanol?
Answer:
3 element i.e carbon (C), hydrogen (H) and oxygen.
Explanation:
The following data were obtained from the question:
Subtance >>>>>>>> Chemical Formula
Glucose >>>>>>>>> C₆H₁₂O₆
Methane >>>>>>>> CH₄
Ethanol >>>>>>>>> C₂H₅OH
Hydrogen peroxide >> H₂O₂
From the above table, we can see that ethanol (C₂H₅OH) contains carbon (C), hydrogen (H) and oxygen
Therefore, the total number of elements present in ethanol, C₂H₅OH is 3.

Explanation:
6-36. Calculate [H ] and pH for the following solutions: (a) 0.010 M HNO 3 (b) 0.035 M KOH (e) (c) 0.030 MHCl
Answer:
a)2
b)12.5
c)1.5
Explanation:
a)
pH = -log [H^+]
pH = -log [0.01]
pH = 2
b)
pOH = -log[OH^-]
pOH = -log [0.035]
pOH= 1.5
But
pH + pOH = 14
pH = 14 - pOH
pH= 14 - 1.5
pH = 12.5
c)
pH = -log[H^+]
pH= -log[0.030]
pH = 1.5
