I don’t get it. What is the question asking?
Answer: 1820 mL (to 3 sf)
Explanation:
The atomic mass of aluminum is 26.9815385 g/mol, so 4.10 g of aluminum is equal to 4.10/26.9815385 = 0.15195575300497 moles of Al.
From the coefficients of the equation, we know that for every 2 moles of aluminum consumed, 6 moles of HCl are consumed.
So, this means we need 0.15195575300497(6/2) = 0.45586725901491 moles of HCl.
Substituting into the molarity formula,
- 0.250 = 0.45586725901491/(liters of HCl)
- liters of HCl = 0.45586725901491/0.250
- liters of HCl = 1.8234690360596 L = 1820 mL (to 3 sf)
Explanation:
Iron, like other metals, conducts heat and electricity, has a luster, and forms positive ions in its chemical reactions. Pure iron is fairly soft and can easily be shaped and formed when hot. Its color is silvery white. Iron is easily magnetized.
I think its pure substance since you are breaking into its components. For example if you were to break the components of salt apart (NaCl) You will be left with sodium and chloride which are the pure elements of salt. Therefore i believe pure is the best answer.
