Answer : The partial pressure of the hydrogen is, 705.9 mmHg
Explanation :
According to the Dalton's law of partial pressure,
![P_T=P_{H_2}+P_{H_2O}](https://tex.z-dn.net/?f=P_T%3DP_%7BH_2%7D%2BP_%7BH_2O%7D)
where,
= total pressure of the gas = 729.7 mmHg
= partial pressure of the hydrogen gas = ?
= partial pressure of the water = 23.8 mmHg (standard value)
Now put all the given values in the above expression, we get:
![729.7mmHg=P_{H_2}+23.8mmHg](https://tex.z-dn.net/?f=729.7mmHg%3DP_%7BH_2%7D%2B23.8mmHg)
![P_{H_2}=705.9mmHg](https://tex.z-dn.net/?f=P_%7BH_2%7D%3D705.9mmHg)
Therefore, the partial pressure of the hydrogen is, 705.9 mmHg
Answer:
the anwser isn't in the choices
Explanation:
H=MC(change of temp.)
M=mass of water=250g
C=specific heat of water = 4.186 j/g
change in temperature is 121-40= 81
H= 250x4.186x81=84766.5J
The answer is Photosphere Apex.
Answer:
Covalent bonding
Explanation:
In covalent bonding, the electrons are shared to fill the octet rule (8 electrons in valence shell). CCl4 tends to do covalent bonding because the the 4 valence electrons are Carbon are shared with the Chlorine atoms so that each chlorine atom has a full octet and chlorine shares its electrons to fill the octet of carbon.
Also, since carbon and chlorine are both non-metal, non-metal things exhibit covalent bonding thus this is covalent bonding as well. Ionic boding is for metal and non metal pair where electrons are transferrred, in our case, electrons are shared, they are not transferred.
