ANSWER

The temperature at which it boils is a measure of its physical property

STEP-BY-STEP EXPLANATION:

Firstly, we need to define the physical and chemical property of matter

The physical property of matter is characteristic of matter that is not associated with a change in its chemical composition. The physical properties include; color, density, hardness, melting, and boiling point.

The chemical property of matter is characteristic of matter that is associated with a change of matter from one type to another type. The chemical properties include; Flammability, toxicity, acidity, reactivity, etc.

When a liquid is boiled, it changes its state from liquid to vapor, this change of state is associated with the physical property of matter.

Hence, the temperature at which it boils is a measure of its physical property

Answer:

The system will change its concentration to shift to a new equilibrium position.

Explanation:

For example in the Haber Process

N2 + 3H2 ⇄ 2NH3

If the pressure is increased the process will move to the right - to have more NH3 and less of the nitrogen and hydrogen.

Why does it take so much heat and pressure to create helium and other elements?

ehidna [41]

Answer:

To break down the nucleus of an atom

Explanation:

Remember to change from one element to another, is necessary to add protons, neutrons and electrons,in most of the cases.

The take an electron from an atom you need certain energy, but they are in the outside part of the atom so is not as much energy as the one is necessary to take one neutron or proton from the inside part of an atom.

In this way, is a must to have a combination of pressure and heat to destabilize an atom and take some of this subatomic particles.

Calculate the percentage difference in the fundamental vibrational wavenumbers of 23Na35Cl and 23Na37Cl on the assumption that t

stealth61 [152]

Answer:

1.089%

Explanation:

From;

ν =1/2πc(k/meff)^1/2

Where;

ν = wave number

meff = reduced mass or effective mass

k = force constant

c= speed of light

Let

ν =1/2πc (k/meff)^1/2 vibrational wave number for 23Na35 Cl

ν' =1/2πc(k'/m'eff)^1/2 vibrational wave number for 23Na37 Cl

The between the two is obtained from;

ν' - ν /ν = (k'/m'eff)^1/2 - (k/meff)^1/2 / (k/meff)^1/2

Therefore;

ν' - ν /ν = [meff/m'eff]^1/2 - 1

Substituting values, we have;

ν' - ν /ν = [(22.9898 * 34.9688/22.9898 + 34.9688) * (22.9898 + 36.9651/22.9898 * 36.9651)]^1/2 -1

ν' - ν /ν = -0.01089

percentage difference in the fundamental vibrational wavenumbers of 23Na35Cl and 23Na37Cl;

ν' - ν /ν * 100

|(-0.01089)| × 100 = 1.089%

A calorie is another term for carbohydrate.TF

Hunter-Best [27]

This is false. A carbohydrate is a carbon-based molecule that can be utilized by living organisms in order to produce energy. A calorie is a unit of energy often used to measure the amount of energy within food. Another example of energy unit is the Joule, more commonly used within physics.
