It is the atomic number. So it is D.
Answer: you can’t
Explanation: i’m dumb too
Explanation:
Relation between
and
is as follows.
![K_{p} = K_{c} [RT]^{\Delta n}](https://tex.z-dn.net/?f=K_%7Bp%7D%20%3D%20K_%7Bc%7D%20%5BRT%5D%5E%7B%5CDelta%20n%7D)
Given, temperature =
= (830 + 273) K = 1103 K
R = 8.314 J/mol K
= 1 - 0 = 1
Now, putting the given values into the above formula as follows.
![K_{p} = K_{c} [RT]^{\Delta n}](https://tex.z-dn.net/?f=K_%7Bp%7D%20%3D%20K_%7Bc%7D%20%5BRT%5D%5E%7B%5CDelta%20n%7D)
0.5 = 

ICE table for the given reaction will be as follows.

Initial: c - -
Equilibrium: (c - x) x x
= ![[CO_{2}]](https://tex.z-dn.net/?f=%5BCO_%7B2%7D%5D)
= x
Hence, same amount of CaO is produced.
Moles of CaO = 
Mass of CaO = 
= 0.310 g
Thus, we can conclude that 0.310 g of CaO produced when equilibrium is established.
Answer:
potassium and sodium
Explanation:
when they react with cold water they produce a metal hydroxide and hydrogen gas
