The group of atoms that is responsible for the characteristic properties of a family of organic compounds is called a/an _______

Sindrei [870]

The group of atoms that is responsible for the characteristic properties of a family of organic compounds is called a functional group.

Functional groups are groups of one or extra atoms with exclusive chemical homes regardless of what's connected to them. The atoms of practical agencies are certain via covalent bonds with one another and with the relaxation of the molecule.

Functional groups include:

hydroxyl,
methyl,
carbonyl,
carboxyl,
amino, phosphate,
sulfhydryl.

An atom or institution of atoms that replaces hydrogen in a natural compound that defines the shape of a family of compounds and determines the properties of the family.

A gas has a pressure of 3 atm at 350°C. What will its pressure be at 250°C? The volume and amount of gas is constant. Hint: Conv

vichka [17]

We are given:

P1 = 3 atm T1 = 623 K (350 + 273)

P2 = x atm T2 = 523 K (250 + 273)

Solving for x:

From the idea gas equation:

PV = nRT

since number of moles (n) , Volume (V) and the Universal Gas constant(R) are constants;

P / T = k (where k is a constant)

the value of k will be the same for a gas with variable pressure and temperature and constant moles and volume

Hence, we can say that:

P1 / T1 = P2 / T2

3 / 623 = x / 523

x = 523 * 3 / 623

x = 2.5 atm (approx)

Therefore, the final pressure is 2.5 atm

A thermally isolated system is made up of a hot piece of aluminum and a cold piece of copper; the aluminum and the copper are in

Illusion [34]

Answer:

Copper is the object that experiences the greater temperature change.

Explanation:

Thermally isolated system means that the system does not exchange thermal energy with the surroundings.

Hence, any thermal exchange, in virtue of the temperature difference of the aluminum and copper pieces, is between them.

In consequence, the law of conservation of energy states that the heat lost by the hot substance will be gained by the cold matter.

In equations, that is:

Heat lost by aluminum = heat gained by copper.

Now, the gain or loss or heat of a substance, Q, is related with the mass (m), the specific heat (Cs), and the cahnge of temperature (ΔT), per the equation:

Q = m × Cs × ΔT

∴ Q lost by aluminum = Q gained copper ⇒

[m × Cs × ΔT ] aluminum = [m × Cs × ΔT ] copper.

Under the reasoning assumption that the masses of aluminum and copper are equal, the equations is simplified to:

[Cs × ΔT ] aluminum = [Cs × ΔT ] copper.

Cs aluminum / Cs copper = ΔT copper / ΔT aluminum

Cs aluminum > 2 × Cs copper ⇒ Cs

Cs aluminum / Cs copper > 2 ΔT copper / ΔT aluminum

ΔT copper / ΔT aluminum > 2

ΔT copper > 2 × ΔT aluminum

In words, since it is stated that the specific heat of aluminum is more than double that of copper, in order to keep the equality, ΔT of copper shall be more than double ΔT of aluminum.

Hence, the conclusion is that the object that experiences the greater temperature change is copper (the one with the lower specific heat), under the assumption that both objects have the same amount of matter (mass).

Aspartame is a sweetner that is 160 times sweeter than sucrose (table sugar) when dissolved in water. The molecular formula of a

NikAS [45]

Answer:

294.307 g/mol

Explanation:

The first question for this statment is:

Calculate the gram-formula-mass of aspartame.

<h2>Solution</h2>

The chemical formula is:

$C_{14}H_{18}N_2O_5 .$

The gram-formula-mass is calculated adding the masses for all the atoms in the molecular formula:

Atom Number of atoms Atomic mass Total mass

g/mol g/mol

C 14 12.011 14 × 12.011 = 164.154

H 18 1.008 18 × 1.008 = 18.144

N 2 14.007 2 × 14.007 = 28.014

O 5 15.999 5 × 15.999 = 79.995

===================

Total 294.307 g/mol

Answer: 294.307 g/mol

A dark purple liquid is diluted by adding water.

alexandr402 [8]

Answer: The process is diffusion.

Explanation:

a dark liquid will have the highest concentration of dark purple atoms/molecules so it gives a concentrated colour.

when water is added to it, the colourless water molecules fill up the gaps between the purple particles and so their colour fades and becomes lighter and lighter as we add more water. see the image attached where imagine the red particles are water and the blue particles are purple particles. thats why the colour fades.
