Answer:
58.94 mL
Explanation:
V1 = 48.3 mL V2 = v mL
T1 = 22 degree celsius OR 295 k T2 = 87 degree celsius OR 360 k
We will use the gas equation:
PV = nRT
Since the Pressure (p) , number of moles (n) and the universal gas constant(R) are all constants in this given scenario,
we can say that
V / T = k , (where k is a constant)
Since this is the first case,
V1 / T1 = k --------------------(1)
For case 2:
Since we have the same constants, the equation will be the same
V / T = k (where k is the same constant from before)
V2 / T2 = k (Since this is the second case) ------------------(2)
From (1) and (2):
V1 / T1 = V2 / T2
Now, replacing the variables with the given values
48.3 / 295 = v / 360
v = 48.3*360 / 295
v = 58.94 mL
Therefore, the final volume of the gas is 58.94 mL

Aldol condensation is an easy way of making carbon-carbon bond.
In the field of chemistry, we can describe aldol condensation as a type of bond that occurs due to electrophilic substitution at the alpha carbons of the enol.
Aldol condensation is known to be the easiest way for one carbon to form bonds with another carbon.
Such an aldol reaction that takes place between carbonyl compunds instead of aldehydes or enols is referred to as crossed aldol condensation.
Aldol reactions are known to be an important part of synthesizing organic compounds as carbon-carbon bonds are formed due to it.

Iron is constantly working to support life on Earth, from supplying plants with nutrients to serving as a key component of steel to carrying oxygen in your blood.
- Iron is the most common metal, its pure form corrodes quickly when exposed to humid air and high temperatures.
- it is abundant in the sun and stars.
- It contributes to the synthesis of chlorophyll in plants.
- It is a part of hemoglobin, a blood protein that transports oxygen from the lungs to the body's tissues in mammals.
- The majority of it is used to create steel, an iron and carbon alloy used in manufacturing.
- There are four main structural forms of iron, known as allotropic forms, in which atoms are bound in various ways.
These are few properties of iron that are unusual for metal.

Answer:
A
Explanation:
Opposite charges attract therefore the electrons of one atom would be attracted by the nucleus (which contains protons). This heavily relies on a property called electronegativity. Which deals with the level of attraction a nucleus (the protons in the nucleus) have for electrons of other atoms.
