The correct answer is C.
On the left:
2 carbon+ 2 oxygen+ 2 oxygen
On the right:
2 carbon+ 4 oxygen (remember to multiply the coefficient and subscript)
Hey there!
The number of molecules is the same.
One mole of a type of molecule is <u><em>always</em></u> 6.022 x 10²³ molecules, so no matter what the type of molecule is there will be the same amount of molecules.
The mass, volume, or other properties can be different, but the number of molecules will be the same.
Hope this helps!
To find the weight of the gas you need to find the number of moles of using ideal gas formula. Remember to change the temperature unit to Kelvin and the pressure to kpa or atm
PV=nRT
n= PV/RT
n= 699 mmHg* 0.1333kpa * 0.357 L/ 8.314 kpa*L / mol*K * (45 +273.15)K
n=<span>0.012 moles
</span>
weight= n * molecular weight
weght= 0.012 *92.448 g/mol= 1.109 grams
I'd say it's partially dissociating into products
324.05 degrees K
To get from C to K just add 273.15
