noble gases are used in many situations where a safe and constant environment must be maintained. for example, helium is used to provide a protective atmosphere for making fiber optics and semiconductors. argon is used to fill incandescent and flourescent light bulbs to prevent oxygen from corroding the hot filament. why are noble gases used in these situations?
Answer:
Noble gases have a complete valence electron shell making them stable and nonreactive.

Explanation:
Why does atomic radii decrease as you move from the left to right across the period
Answer:
This is because, within a period or family of elements, all electrons are added to the same shell.
When we move from left to right across the periodic table, we can see that the atomic radii keeps decreasing. This is because, as you move from left to right, the nucleus gains protons. The atomic number increases and hence the valence electron will feel more attracted towards the nucleus & the atomic radii will decrease.

a 7.221 g sample of a compound contains 1.990 g carbon, 2.341 g hydrogen, and the rest is oxygen. Determine the
percent composition of the compound
Answer:
17.19%
Explanation:
mass of oxygen = 7.221 - (1.990 + 2.341)
= 2.890g
Empirical formula of the compound
For carbon,
1.990/12 = 0.1658
For hydrogen,
2.341/1 = 2.341
For oxygen,
2.890/16 = 0.1806
0.1658 ÷ 0.1658 = 1
2.341 ÷ 0.1658 = 14.11
0.1806 ÷ 0.1658 = 1.089
Empirical formula of the compound= CH14O
Molar mass= (1×12) + (14×1) + (1×16)
= 12+14+16
= 42g/mol
percentage composition= 7.221/42 × 100
= 17.19%

How many moles of AgCl can form from 6.5 moles of Ag and abundant HCl in the equation: 2Ag + 2HCl -> 2AgCl + H2
6.5 moles of AgCl can be formed from 6.5 moles of Ag.
STOICHIOMETRY:
According to this question, silver reacts with hydrochloric acid to form silver chloride and hydrogen gas as follows:
2Ag + 2HCl → 2AgCl + H2
Based on this balanced equation, 2 moles of silver (Ag) produces 2 moles of silver chloride (AgCl).
This means that 6.5 moles of Ag will produce (6.5 × 2)/2 = 6.5 moles of AgCl.

How does distillation remove hardness from water
Answer:
Distillation can be used to soften water as the water evaporates as it is heated and the ions are left behind.
Hope that helps. x
Answer: Distillation can be used to separate and collect a liquid from a solution. Distillation can also be used to soften water as the water evaporates as it is heated and the ions are left behind. Hard water can be softened by adding sodium carbonate (washing soda) or by passing the water through an ion-exchange column.
