Answer:
2Fe + O₂ -------------------> 2FeO
8 mol Fe produce
8 mol Fe * 2 mol FeO / 2 mol Fe = 8 mol FeO
Mass of FeO = 8 mol FeO * 71.85 g/mol = 574.8 grams FeO
Explanation:
Having 8 mol of Iron means 8 moles of iron oxide can be produced. Each mole of iron oxide has a molecular weight of 71.85 grams. Therefore, 8 moles of iron oxide should weight 574.8 grams.
Explanation:
The given data is as follows.
T = = (11 + 273) K = 284 K, V = 45.0 L
m = 35 g
As molar mass of chlorine pentafluoride is 130.445 g/mol. Hence, number of moles of chlorine pentafluoride are as follows.
No. of moles =
=
= 0.268 mol
Now, using the ideal gas equation we will find the pressure as follows.
PV = nRT
P = 0.139 atm
Thus, we can conclude that pressure of chlorine pentafluoride gas in the given reaction vessel after the reaction is 0.139 atm.
1-stars are born in a region of high density nebula, and condenses into a huge globule ig has a dust and contrast under its own gravity.
The electron configuration for zinc is [AR] 4S2 3D10. Zinc has atomic number 30 and is the first element in group 12 of the periodic table. The last option is the correct one. Electron configuration has to do with the distribution of electrons in an atom or molecule in atomic or molecular orbitals. Electronic configuration of an element is very important because it is the key to the properties of that element.
A homogeneous mixture is A. Pure substance.
