Answer:
The answer to your question is 576 grams of FeO
Explanation:
Balanced chemical reaction
2Fe + O₂ ⇒ 2 FeO
Reactant Elements Products
2 Fe 2
2 O 2
Data
mass of FeO = ?
moles of Fe = 8
Excess Oxygen
Process
1.- Convert moles of Fe to grams
Atomic mass = 56 g
56 g of Fe ------------------ 1 mol
x ------------------ 8 moles
x = (8 x 56) / 1
x = 448 g of Fe
2.- Use the coefficients of the balanced reaction to find the grams of FeO.
Molecular mass of FeO = 2[ 56 + 16]
= 144 g
2(56) g of Fe ----------------------- 144 g of FeO
448 g ----------------------- x
x = (448 x 144) / 2(56)
x = 64512 / 112
x = 576 grams of FeO
If an organism reproduces quickly, its population can evolve faster.
it will sink
Explanation:
the solid iron will sink because it is dense than the liquid iron I will sink and it will melt
Answer:
Filtration is a method for separating an insoluble solid from a liquid. When a mixture of sand and water is filtered: the sand stays behind in the filter paper (it becomes the residue ) the water passes through the filter paper (it becomes the filtrate )

Answer:
Reverse the
reaction
Explanation:
Reactions:
![N_2O_4 \longrightarrow 2 NO + O_2](https://tex.z-dn.net/?f=N_2O_4%20%5Clongrightarrow%202%20NO%20%2B%20O_2)
Overall:
![N_2O_4 \longrightarrow 2 NO_2](https://tex.z-dn.net/?f=N_2O_4%20%5Clongrightarrow%202%20NO_2)
As can be seen, in the overall reaction we have
in the reactants like in the second reaction and
in the products. The
is in the first reaction but as a reactant so we need to reverse that reaction:
![N_2O_4 \longrightarrow 2 NO + O_2](https://tex.z-dn.net/?f=N_2O_4%20%5Clongrightarrow%202%20NO%20%2B%20O_2)
Combining:
![N_2O_4 + 2 NO + O_2\longrightarrow 2 NO + O_2 + 2 NO_2](https://tex.z-dn.net/?f=N_2O_4%20%2B%202%20NO%20%2B%20O_2%5Clongrightarrow%202%20NO%20%2B%20O_2%20%2B%202%20NO_2)
![N_2O_4 \longrightarrow 2 NO_2](https://tex.z-dn.net/?f=N_2O_4%20%5Clongrightarrow%202%20NO_2)
