O in moles is 16.0 grams and theres 6.02 * 10 /\23 atoms in it, but when asked for one mole of O2 ( in grams) why is it 32.0 grams because that would mean that theres 2 * 6.02 * 10 /\23 atoms in it. I
Hope you can help,please explain in details if you could. Thank you-Your question as written doesnt make sense. I presume you meant to say: Why alkanes and their corresponding alkenes have similar phy
What mass of solid potassium oxalate (K2C2O4), when dissolved in an acidic solution, would be titrated by exactly 25.0 mL of 0.0347 M potassium permanganate (KMnO4) solution? (Mn2+ ions and carbon dio
I would guess two lol but that wasnt on the multiple choice. Im lost.-They are both stable isotopes of Chlorine.
35Cl has 17 protons and 18 neutrons in the nucleus. 37Cl has 2 more neutrons in its nu
Okay, so say that you are converting a random number like 151 ft. into meters. Okay so I understand that 151ft x 1yards/3ft x 0.914m/1 yard if you cancel and multiply divide blah blah blah you get lik
If I were to account for sig figs in this question:
0.002650103...cm^3 / 333.4084 cm^2
= 0.000007948 cm
the number with the LEAST amount of sig figs, has 7 sig figs if I am correct--but from what I
a) Ba^2+
b) P^3-
c) Mn^2+
i dont get it! help appreciated, x_x-a) Ba^2+ == A neutral Ba atom has 56 electrons, the ion has 54 electrons
b) P^3- == A neutral phosphorous atom has 15 electrons, the
A mass of 130. g of a metal is heated to 135 °C and placed in 250. mL of water at 21.3°C. If the final temperature of the water is 45.8 °C, calculate the specific heat of the metal in J/(°C g).
Pleas
How will the volume be affected?
Please help with Chem question. Please show formula and how I figure this out. Thank you.-P1V1/T1 = P2V2/T1

Acetaminophen is the active ingredient in Tylenol. It consists of 63.56% C, 6.00% H, 9.27% N, and 21.17% O. What is the empirical formula of acetaminophen?-Empirical formula of acetaminophen : C8H9NO2
No. of moles of H+ in HCl = 0.5L x 0.5M = 0.25mole
No. of moles of H+ in H2SO4 = 2(0.5L x 0.0048M) = 0.0048mole
(Note: 1 mole H2SO4 = 2moles H+)
Total No. of moles of H+ = 0.2548mole and total Volume

A 195-g sample of a metal was heated to 120.0 degrees C, and then placed into 200.0g water at 21.8 degrees C. The final temperature of the water was measured to be 52.5 degrees C. Calculate (a) the he
this is for chemistry thank you !!-The interactions between neutrons and protons are what keeps the nucleus together.
If there were more protons than neutrons, the nucleus would fly apart.
