Answer:
1. Water can separate from salt solution by simple distillation
2. Simple distillation happens through a process heating and cooling liquids in order to separate the purify them, first, a liquid is heated producing a vapor, then, that vapor is cooled in a small tube called a condenser in order to form a separate liquid that liquid, sometimes referred to as the distillate, falls from the condenser into a separate container, the process works because it to liquids in the original vaporized a different point, meaning, the vapor that is created is comprised entirely of just one of the liquids in order for a simple work the 2 liquids boiling point must have been between at least 25 degrees Celsius about 77 degrees Fahrenheit
Explanation:
ig u can get info from the 2. to help u srry I don't feel like correcting my grammar but I hope that makes sense :)
Oxygen is released as a gas after the water is split.
Any chemical reaction such as combustion, oxidation, decomposition, cellular respiration, etc.
Answer:
Is an exemplar of Italian Renaissance painting.
Explanation:
the Kingdom to St. Peter is an exemplar of Italian Renaissance painting. The work was part of a large decorative program commissioned by Pope Sixtus IV in 1481 for the walls of the Sistine Chapel (the name “Sistine” being derived from Sixtus’ own name), which was then, as it is today, the pope’s private chapel in the Vatican, in Rome.
Answer: 88.2 g
Solution:
1) Chemical equation:
<span>2Al (s) + 3Fe(NO3)2 (aq) → 3Fe (s) + 2Al(NO3)3 (aq)
2) Theoretical molar ratios
2 mol Al : 3 mol Fe(NO3)2 : 3 mol Fe : 2 mol Al(NO3)3
3) Starting mass of pure iron nitrate
% = (mass of iron nitrate / mass of solution) * 100 = 87.5
=> mass of iron nitrate = 87.5 * mass of solution / 100
mass of solution = 325 g
=> mass of iron nitrate = 87.5 * 325 g / 100 = 284.375 g
4) moles of iron nitrate
moles = mass in grams / molar mass
molar mass of Fe(NO3)2 = 179.85 g/mol
moles = 284.375 g/ 179.85 g/mol = 1.58 moles Fe(NO3)2
5) proportion:
x 3 mol Fe
--------------------------- = ----------------------
1.58 mol Fe(NO3)2 3 mol Fe(NO3)2
Clear x:
x = 1.58 mol Fe
6) Convert 1.58 mol Fe into grams
mass = number of moles * atomic mass
atomic mass of iron = 55.845 g / mol
mass = 1.58 moles * 55.845 g/mol = 88.24 g
Rounded to 3 significant figures: 88.2 grams of Fe.
