The relative atomic mass of carbon isn't 12 exactly because the weight of one of the isotopes of carbon, carbon-13 is taken into account as well; this has an abundance of about 1.1%.
I think it’s OH I’m not sure
<span>The behavior, or reactivity, of elements in a group, or family will behave similarly because they have the same numbers of valence electrons. An example might be the alkali metals (with the exception of hydrogen, H, which is a gas) which form +1 ions in their compounds, have a relatively low melting point, and react violently with water. Other groups of atoms also show similar properties although different from the alkali metals. This type of behavior is one of the things that helps us categorize the elements into the periodic table of the elements. Mendeleev noticed similarities in the behavior of certain elements that originally allowed him to place them into families and develop that periodic chart</span>
Answer: Fe2O3
Explanation:
100 grams of iron ore = 30.06% oxygen
100 - 30.06 = 69.94% iron
Mr of Iron = 55.85
Mr of Oxygen = 16
Iron = 69.94/55.85 = 1.252
Oxygen = 30.06/16 = 1.879
1.879 / 1.252 = 1.5 of Oxygen
1.252/1.252 = 1 of Iron
we can write that as Fe1O1.5 but we can't use decimals therefore we have to multiply the whole thing by 2
So it comes out to be Fe2O3
Answer:
Digestion is the breaking down of food into simpler substances.Ingestion is the process of taking the food in.Absorption is the process of absorbing the nutrients and water into the bloodstream.Assimilation is the process of utilization of absorbed nutrients by the cells.
