Answer:
C) 
Explanation:
pH is defined as the negative logarithm of the concentration of hydrogen ions.
Thus,
pH = - log [H⁺]
The expression of the pH of the calculation of weak acid is:-
Where, C is the concentration = 0.5 M
Given, pH = 2.94
Moles = 0.100 moles
Volume = 1.00 L
So, 
C = 0.100 M



There isn t a 'middle' carbon because there is an even number of them
If the methyl group braches off the 3rd carbon the name is
hexa-3-methyl-3-ene
<span>Answer – We are given, 2H2+O2 ----> 2H2O , deltaH = -48.4 kJ Moles of H2 =1.8 moles From the above given balanced equation We know, 2 moles of H2 = -48.4 kJ So, 1.8 moles of H2 = ? kJ = 1.8 moles of H2 X -48.4 kJ / 2 moles of H2 =-43.6 kJ So, when 1.8 mol of H2...</span>

From the notes my teacher gave me.
Hopefully this helps, have a nice day.
Also by any chance, do you go to Freedom High School?
Answer:
See explanation
Explanation:
Microwaves work by flipping water molecules upside down, then right side up again, and so on at very high speeds, and the friction generates heat. Some glass or plastic isn't affected by the microwaves, so the molecules don't get flipped, and so no friction occurs and no heat is produced, leading to the dish not being heated up.
