Answer: The correct answer is Option B.
Explanation:
To calculate the number of moles, we use the formula:
Molar mass of iron = 55.8 g/mol
Given mass of iron = 558.8
Putting values in above equation, we get:
For the given chemical equation:
By Stoichiometry,
4 moles of Iron produces 2 moles of Iron(III) oxide
So, 1 mole of Ion will produce = 
= 0.5 mole of Iron (III) oxide.
Hence, the correct answer is Option B.
Electrons uniting with electrons of another atom is the cause in this relationship. The effect is a chemical change.
This would be 8.010 * 10^-2
Answer:
Explanation:
Metal elements form positively charged ions called cations because they are located on the left side of the periodic table These elements all have valence electrons in an s orbital. These electrons are relatively easy for the atom to lose to achieve a stable octet of electrons in its outermost energy shell.
