Protons and neutrons are both inside an atom, squished tightly together. <span />
Depending on how much bleach you use, the type fabric and the original red dye, you could end up with a washed-out dull red, or orange or some variety of pink.
We are given with
V = <span>2.394 x 102 mL
P = </span><span>7.20 x 102 mm of Hg
T = </span><span>78 oC
We are asked to determine the mass of the sample in milligrams
Using the ideal gas law
n = PV / RT
n = </span>7.20 x 102 mm of Hg (2.394 x 102 mL) / R (78 + 273)
Use the appropriate value for R or just convert the values to SI and use R = 8.314
Then, solve for the mass of the sample by using the MW Oxygen which is 16 g/mol
60 i believe i haven't did science in a while sorry if im wrong though... ._.
The total charge of a compound must be zero. So the Y ion has charge of -2. Then the charge of X ion+(-2)*2=0. So the charge of X ion is +4.
