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.
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:
c) a compound
Explanation:
a compound is something made up of two or more separate elements, the separate elements in water are hydrogen(H) and oxygen(O)
Answer:
Look below
Explanation:
The formula for density is:
Therefore in order to find the density of a solid, you must find the mass and the volume first.
To find the mass, you can use a scale.
To find the volume, you can use the water displacement method. For example, if you fill the water of a graduated cylinder to 10 mL, and then you put a rock inside, and it rises to 15 mL, then the volume (of the rock) is 15mL-10mL=5mL.
Answer:
No. You can not simplify a coefficient of.
