Answer:
0.453 moles
Explanation:
The balanced equation for the reaction is:
2Fe(s) + 3O2(g) ==> 2Fe2O3
From the equation, mass of O2 involved = 16 x 2 x 3 = 96g
mass of Fe2O3 involved = [(2x26) + 3 x 16] x 2
= 100g
Therefore 96g of O2 produced 100g of Fe2O3
32.2g of O2 Will produce 100x32.2/96
= 33.54g of Fe2O3
Converting it to mole using number of mole = mass/molar mass
but molar mass of Fe2O3 = 26 + (16 X 3)
= 74g/mole
Therefore number of mole of 33.54g of Fe2O3 = 33.54/74
= 0.453 moles
There is 0.02538502095915 Moles in 5 grams of gold.
Answer:
Both
compounds in left hand side of the equation is called reactants.
compounds in right hand side of the equation is called products.
so ans is both water and carbon di oxide
Explanation:
Answer:
Option D - It tells which compounds will dissolve in water.
Explanation:
It is used to predict whether or not a given ionic compound is soluble.
13111 is already an integer (whole number). It also can be expressed as 1 ton or 13111000g.
