Aluminium reacts with dilute sulfuric acid based on the following reaction: <span>2Al + 3H2SO4 ..............> Al2 (SO4)3 + 3H2
From the periodic table: mass of aluminium = 27 grams mass of hydrogen = 1 gram mass of oxygen = 16 grams mass of sulfur = 32 grams
Therefore: molar mass of aluminium = 27 grams molar mass of sulfuric acid = 2(1) + 32 + 4(16) = 98 grams
From the balanced chemical equation: 2 moles of aluminium react with 3 moles of dilute sulfuric acid. This means that 34 grams of Al react with 294 grams of the acid
To get the amount of aluminium that reacts with </span><span>5.890 g of sulfuric acid, we will do cross multiplication as follows: </span>amount of Al = (<span>5.890 x 34) / 294 = 0.6811 grams</span>
<span>The volume of iron is obtained from the density formula (density= mass/ volume) given the density and mass. In this case, 4,540 grams of iron and a density of 7.86 g/ml are given. The volume obtained from formula is 493.64 ml or 5.78 dL. </span>
If an an element has an atomic number of 60, then there would me 60 protons. Something that helps me is APE. The atomic number is the same as the number of protons and electrons.
