Ionic bonds is formed between a metal and a nonmetal because the metal transfers it's valence electrons to the nonmetal. Electrons doesn't transfer between two nonmetal because both are negatively charged.
Answer:
d.
Explanation:
i was think b at first but that doesnt really explain how it gets to the circulatory system so d because without the the regulation of the heart rate and oxgen rich blood the muscular system can do absolutely nothing
That totally depends on the experiment that you did
The theoretical yield of iron metal : 16.418 g
<h3>Further explanation</h3>
A reaction coefficient is a number in the chemical formula of a substance involved in the reaction equation. The reaction coefficient is useful for equalizing reagents and products.
Reaction
2 Fe₂O₃ + 3 C ⇒ 4 Fe + 3 CO₂
mol Fe₂O₃ (MW=159,69 g/mol) :
mol Fe₂O₃ : mol Fe = 2 : 4
mol Fe :
mass Fe(the theoretical yield) :
