Answer:
Hydrogen ion concentration is 2.773E-4Mole per DM3
Hydroxide ion concentration is 4.093E-11
It is an acid
Explanation:
PH(H3O)=-LogH3O
PH=3.557
H3O=antilog of -3.557
antilog of -3.557=antilog (0.443 -4)
antilog0.443 ×antilog -4=2.773E-4mole per DM3.
(H3O)(OH)=10^-14
H30=2.773×10^-14
OH= 1.00E-14/2.773E-4
=4.093E-11
it is an acid since the concentration of hydrogen ion is more than the hydroxide ion
Answer: 0 I think
Explanation:
pretty sure its zero because i learned it last year but im in middle school so you might want to look it up.
Answer:
Yes. There must be a difference.
Explanation:
The part of water with low density (warm or hot) would rise, and the cold water would sink. This creates a convection.
Answer:
0.484 mole
Explanation:
1 mole of glucose reacts with 6 moles of O2, producing :
6 moles of CO2
6 moles of H2O
678 kcal
Using rule of three you have:
1 mole of glucose -> 678 kcal
x mole of glucose -> 328 kcal
x = 328/678 * 1 =0.484 mole
Based on nuclear stability, the symbol for the most likely product nuclide obtained when nitrogen-13 undergoes decay is coming from the following equation:
₇N¹³ → Positron₊₁⁰ + ₆C¹³
So the correct answer will be ₆C¹³
