Answer:
a) 8×10²³ molecules of N2
Explanation:
Let us consider the same temperature and pressure of both sample are standard temperature and pressure.
Standard temperature = 273.15 K
Standard pressure = 1 atm
Number of moles of CO₂ = 0.107 mol
Volume of CO₂ = ?
Solution:
PV = nRT
R = general gas constant = 0.0821 atm.L /mol.K
1 atm × V = 0.107 mol × 0.0821 atm.L /mol.K × 273.15 K
1 atm × V = 2.4 atm.L
V = 2.4 atm.L/1 atm
V = 2.4 L
Volume of N₂:
Number of moles of N₂:
1 mole = 6.022 ×10²³ molecules
8×10²³ molecules × 1 mol / 6.022 ×10²³ molecules
1.33 mol
PV = nRT
R = general gas constant = 0.0821 atm.L /mol.K
1 atm × V = 1.33 mol × 0.0821 atm.L /mol.K × 273.15 K
1 atm × V = 29.83 atm.L
V = 29.83 atm.L/1 atm
V = 29.83 L
P1=836kPa
T1=54.7+273=327.7K
P2=836+79.9=915.9kPa
T2=?
T2=T1*P2/P1
=327.7*915.9/836
=359K=86 degree celsius

Answer:
Hydrogen sulfide is used primarily to produce sulfuric acid and sulfur. It is also used to create a variety of inorganic sulfides used to create pesticides, leather, dyes, and pharmaceuticals. Hydrogen sulfide is used to produce heavy water for nuclear power plants (like CANDU reactors specifically).

A sample of material is found to have a mass if 33.03 grams (g), and a volume of 2.624 ml, hence the metal is Silver.
∴ Silver = 12.59 g/mL
The elements of group 11 (Cu, Ag, and Au) are called coinage metals because they are used in minting coins. These metals are malleable. They have the ability to get converted into sheets.
The coinage metal comprise, at a minimum, those metallic chemical elements which have historically been used as components in alloys used to mint coins.
The coinage metals have the highest electrical and thermal conductivities of all the metals, and they are also the most ductile and malleable.
