The standard temperature and the pressure for a gas are 273 K and 1 atm (1.0 x 10⁵ Pa) respectively.
For this question, combined gas law can be added.
PV/T = K (constant)
for both situations that law can be added as;
P₁V₁/T₁ = P₂V₂/T₂
P₁ = 97 kPa P₂= 1.0 x 10⁵ Pa
T₁ = 303 K T₂ = 273 K
V₁ 140 mL V₂ = ?
V₂ = 122.3 mL
Hence, the volume of gas at STP = 122.3 mL
The type of covalent bond is formed between amino acid molecules during protein synthesis will be <u>"peptide bond".</u>
<u />
A peptide bond would be a sort of covalent link that connects an amino acid's carboxyl group to its amino group. Amino acids itself were comprised of atoms bonded together through covalent bonds.
Two atoms share an electron pair equally in a covalent link. Peptide (amide) but also disulfide links between amino acids, as well as C-C, C-O, and C-N bonds within amino acids, represent examples of significant covalent bonds.
Therefore, the type of covalent bond is formed between amino acid molecules during protein synthesis will be <u>"</u><u>peptide bond"</u><u>.</u>

Given parameters:
Initial volume = 120ml
Initial temperature = 35°C
Initial pressure = 1.2bar
Final volume = 180ml
Final temperature = 35°C
Unknown:
Final pressure = ?
To solve this problem, we apply the combined gas law. The expression is given below;
Where P₁ is the initial pressure
P₂ is the final pressure
V₁ is the initial volume
V₂ is the final volume
T₁ is the initial temperature
T₂ is the final temperature
We need to convert the parameters to standard units
take the volume to dm³;
1000ml = 1dm³
120ml = 
dm³ = 0.12dm³ = initial volume
Final volume;
1000ml = 1dm³
180ml = 
dm³ = 0.18dm³
Now, the temperature;
K = 273 + °C
Initial temperature = 273 + 35 = 308k
Final temperature = 308k
We then input the parameters into the equation;
Solving for P₂;
P₂ = 0.8bar
The new pressure or final pressure in the vessel is 0.8bar

The volume (in dL) of the piece of iron having a mass of 3.92 kg is 4.99 dL
<h3>What is density? </h3>
The density of a substance is simply defined as the mass of the subtance per unit volume of the substance. Mathematically, it can be expressed as
Density = mass / volume
<h3>How to determine the volume of the iron</h3>
From the question given above, the following data were obtained:
- Mass of iron = 3.92 kg = 3.92 × 1000 = 3920 g
- Density of iron = 7.86 g/cm³
- Volume of iron =?
Density = mass / volume
Thus,
Volume = mass / density
Volume of iron = 3920 / 7.86
Volume of iron = 498.7277 cm³
Divide by 100 to express in dL
Volume of iron = 498.7277 / 100
Volume of iron = 4.99 dL
Thus, the volume of the iron is 4.99 dL
