There is 4.60 g of methane (CH4) and it reacts with an excess amount of O2 gas during a combustion reaction
forming CO2 and H20. One of the products, carbon dioxide, fills a 5.0 L container and has a temperature of 328K.
Assuming only the carbon dioxide goes into the container and the container is closed, what is the pressure inside
the container in kPa? (Hint: need to balance an equation for the reaction and use stoichiometry)

the dependant variable is spilled water

the independent is the heat

hi my dude or dudette

percent abundance for cu-63 can be shown as:

63 x + 65 (1-x) = 62.9296

65 - 62.9296 = 2 x

x = 1.035

thus, percent abundance for cu-63 is 1.035

percent abundance for cu-65 can be shown as:

63 x + 65 (1-x) = 64.9278

65 - 64.9278 = 2 x

x = 0.0361

thus, percent abundance for cu-63 is 0.0361

the mass spectrum of cu-63 showing the intense peak as, this isotope is found in nature more abundantly around 92.38 % in comparison to cu-65 which is found 62.58 % naturally
