Answer:
19.18g of iron
Explanation:
To find the mass of iron, we simply find the amount of the ore in grammes that corresponds to 17.7% iron.
We can do this mathematically. We simply place the 17.7 over 100 and multiply by the total mass of the iron.
The mass of iron in the ore is thus: 17.7/100 * 92.3 = 19.18g
The ore simply contains a mass of 19.18g of iron

Answer:
Transition metals can have multiple oxidation states because of their electrons. The transition metals have several electrons with similar energies, so one or all of them can be removed, depending the circumstances. This results in different oxidation states. please mark me as brainellist
Answer: A
Explanation:
A Gold (Au) atom has 79 protons and 79 electrons. A typical gold atom has 118 neutrons, though there are 18 other radioisotopes discovered so far. 79 is its charge (atomic number), which is both its proton number and electron number
