Answer:
Because carbon has one more proton than boron. Carbon has six and Boron has five.
Explanation:
Because it has more subatomic particles. It has one more proton, one more neutron (usually), and one more electron than boron.
Answer:
The value of
at 4224 K is 314.23.
Explanation:
![O_2(g)\rightleftharpoons 2O(g)](https://tex.z-dn.net/?f=O_2%28g%29%5Crightleftharpoons%202O%28g%29)
Initially
4.97 atm 0
At equilibrium
4.97 - p 2p
At initial stage, the partial pressure of oxygen gas = =4.97 atm
At equilibrium, the partial pressure of oxygen gas = ![p_{O_2}=0.28 atm](https://tex.z-dn.net/?f=p_%7BO_2%7D%3D0.28%20atm)
So, 4.97 - p = 0.28 atm
p = 4.69 atm
At equilibrium, the partial pressure of O gas = ![p_{O}=2p=2\times 4.69 atm=9.38 atm](https://tex.z-dn.net/?f=p_%7BO%7D%3D2p%3D2%5Ctimes%204.69%20atm%3D9.38%20atm)
The expression of
is given as :
![K_p=\frac{(p_{O})^2}{(p_{O_2})}](https://tex.z-dn.net/?f=K_p%3D%5Cfrac%7B%28p_%7BO%7D%29%5E2%7D%7B%28p_%7BO_2%7D%29%7D)
![K_p=\frac{(9.38 atm)^2}{0.28 atm}=314.23](https://tex.z-dn.net/?f=K_p%3D%5Cfrac%7B%289.38%20atm%29%5E2%7D%7B0.28%20atm%7D%3D314.23%20)
The value of
at 4224 K is 314.23.
Answer: d: They are poor conductors of heat and electricity
.
Explanation:
Although is common knowledge that metals are characterized by high electrical conductivity and heat conductivity, these properties can be justified by looking at the metallic bonding.
<u>In a metal, the bonding electrons are delocalized over the entire crystal</u>. In fact, metal atoms in a crystal can be imagined as an array of positive ions immersed in a sea of delocalized valence electrons.<u>The mobility of the delocalized electrons makes metals good conductors of heat and electricity.
