Explanation: A gamma ray primarily consists of pure energy and no mass.
Answer:
hot air rises and expanded the balloon
Explanation:
thats it.
<u>Answer:</u>
<em>0.264 g of
can be formed from 288 mg of
</em>
<u>Explanation:</u>
The balanced chemical equation is
![2 C_3 H_7 OH+9 O_2> 6 CO_2+8 H_2 O](https://tex.z-dn.net/?f=2%20C_3%20H_7%20OH%2B9%20O_2%3E%206%20CO_2%2B8%20H_2%20O)
The conversions are
Mass in mg
is converted to mass in g
Mass in g
is converted to moles
by dividing with molar mass
Moles
is converted to moles
by using the mole ratio of
is 9 : 6
Moles
is converted to mass
by multiplying with molar mass ![CO_2](https://tex.z-dn.net/?f=CO_2)
mass in mg
> mass in g
>moles
> moles
> mass ![CO_2](https://tex.z-dn.net/?f=CO_2)
![288mg O_2 \times \frac{(1g O_2)}{(1000mg O_2 )} \times \frac {(1molO_2)}{(32gO_2 )}\times\frac {(6mol CO_2)}{(9mol O_2 )} \times \frac {(44.0 gCO_2)}{(1mol CO_2 )}](https://tex.z-dn.net/?f=288mg%20O_2%20%5Ctimes%20%5Cfrac%7B%281g%20O_2%29%7D%7B%281000mg%20O_2%20%29%7D%20%5Ctimes%20%5Cfrac%20%7B%281molO_2%29%7D%7B%2832gO_2%20%29%7D%5Ctimes%5Cfrac%20%7B%286mol%20CO_2%29%7D%7B%289mol%20O_2%20%29%7D%20%5Ctimes%20%5Cfrac%20%7B%2844.0%20gCO_2%29%7D%7B%281mol%20CO_2%20%29%7D)
