Answer
Same amount of protons and neutrons
Explanation
Atoms are electrically neutral because they have equal numbers of protons (positively charged) and electrons (negatively charged). If an atom gains or loses one or more electrons, it becomes an ion.
<u>Answer:</u> The mass of carbon monoxide required is 1.094 kg
<u>Explanation:</u>
The number of moles is defined as the ratio of the mass of a substance to its molar mass. The equation used is:
......(1)
Given mass of iron (III) oxide = 2.08 kg = 2080 g (Conversion factor: 1 kg = 1000 g)
Molar mass of iron (III) oxide = 159.69 g/mol
Plugging values in equation 1:
The given chemical equation follows:
By the stoichiometry of the reaction:
If 1 mole of iron (III) oxide reacts with 3 moles of CO
So, 13.02 moles of iron (III) oxide will react with = of CO
Molar mass of CO = 28.01 g/mol
Plugging values in equation 1:
Hence, the mass of carbon monoxide required is 1.094 kg
