CO2 produced by astronauts on space mission needs to be eliminated from the air as it is detrimental to the astronauts. Engineers created a device that reacts the CO2 with LiOH to produce Li2CO3. Colu
How many SO2 molecules are there in 1 mole sample of SO2 ?
I guess there are 6.022 X 10^23 SO2 molecules.
How many atoms are there in 1 mole sample of SO2 ?Each particle contains 1atom S and 2 atoms
Im really confused. Something about pH = -log [H3O+] when the base to the log is -10. How am I supposed to plug all this into the calculator?
For #1, I have 0.1 mol L-1 [H3O+] concentration.
Thank y
When carbon is burnt in excess oxygen, the only product is carbon dioxide. calculate the volume of CO_2(g) at 120 degrees celsius and 1.20 atm produced from 2.8 g of carbon.
Need this question answer
best answer for right answer! quick please!-Charles Law
V1/T1 = V2/T2
1.86 L / 353 K = x / 305.5 K
x = 1.61 L
Note the use of Kelvin rather than Celsius.
