11. You are a scientist studying the properties of an unknown substance. You made three distinct observations: 1.) Mass = 92.63 kg
2.) Volume = 12.173 cm
3.) Temperature = 101 °F
What is the mass in grams?
A. 926.3 grams
B. 9,263 grams
C. 92,630 grams
D. 926,300 grams
What is the density of the unknown substance?
A 760.9 g/cm
B. 7.609 g/cm
C. 14, 210 g/cm
D 1.421 g/cm3

Plz choose one of the compounds from the table and explain how you know the numbers of atoms in your formula. is it possible for two different compounds to be made from the exact same two elements? why or why not? with a limited number of elements (less than 120 are known), does this mean we also have a small number of compounds or do we have a large number of compounds in this world?

Can someone me with these questions plz.

The conventional equilibrium constant expression (kc) for the system below is: 2icl(s) ⇄ i2(s) + cl2(g) [cl2] ([i2] + [cl2])/2[icl] [i2][cl2]/[icl]2 none of the listed answers are correct [i2][cl2]/2[icl]
