71.8 g of iron (III) oxide (Fe₂O₃) were produced from 3 moles of magnesium oxide (MgO).
Explanation:
We have the following chemical reaction:
2 FeCl₃ + 3 MgO → Fe₂O₃ + 3 MgCl₂
We see from the chemical reaction that 3 moles of magnesium oxide (MgO) will produce 1 mole of iron (III) oxide (Fe₂O₃).
number of moles = mass / molar weight
mass = number of moles × molar weight
mass of Fe₂O₃ = 1 × 71.8 = 71.8 g

This is true! Heterozygous would be Dd, and the dominant masks the recessive
Answer:
Metals, non metals and metalloid
Explanation:
Answer:

Explanation:
Hello,
In this case, we use the ideal gas equation to compute the volume as shown below:

Nonetheless we are given mass, for that reason we must compute the moles of gaseous fluorine (molar mass: 38 g/mol) as shown below:

Thus, we compute the volume with the proper ideal gas constant, R:

Best regards.
