Answer:
Explanation:
The pressure of a gaseous mixture is equal to the sum of the partial pressures of the individual gases:
Σ
![= P_1+P_2+P_3+...+P_n](https://tex.z-dn.net/?f=%3D%20P_1%2BP_2%2BP_3%2B...%2BP_n)
The prompt is trying to confuse you, but it actually tells us the pressure of the mixture to be 1 atm, but this can be converted to torr. Furthermore, we are informed only three gases are in the mixture: diatomic nitrogen, diatomic oxygen, and carbon dioxide:
![P_g_a_s=1 \ atm = 760 \ torr= P_N_2+P_O_2+P_C_O_2\\760 \ torr = 582.008 \ torr + P_O_2 \ + 0.285 \ torr](https://tex.z-dn.net/?f=P_g_a_s%3D1%20%5C%20atm%20%3D%20760%20%5C%20torr%3D%20P_N_2%2BP_O_2%2BP_C_O_2%5C%5C760%20%5C%20torr%20%3D%20582.008%20%5C%20torr%20%2B%20P_O_2%20%5C%20%2B%200.285%20%5C%20torr)
Solve for Po2:
![P_o_2=(760-582.008-0.285) \ torr = 177.707 \ torr](https://tex.z-dn.net/?f=P_o_2%3D%28760-582.008-0.285%29%20%5C%20torr%20%3D%20177.707%20%5C%20torr)
Thus, the partial pressure of diatomic oxygen is 177.707 torr.

Foods are a solid we need to survive
Answer: (3) silicon
Explanation:
Element is a pure substance which is composed of atoms of similar elements.It can not be decomposed into simpler constituents using chemical reactions.Example: Silicon (Si)
Compound is a pure substance which is made from atoms of different elements combined together in a fixed ratio by mass.It can be decomposed into simpler constituents using chemical reactions. Example: ethane
, propanone
and water ![(H_2O)](https://tex.z-dn.net/?f=%28H_2O%29)
