Carboxyl group  
These mixes containing the well bonded functional group (— COOH) are known as carboxylic acids or natural acids. They can give a hydrogen particle (proton) to the whole solution because of a profoundly polar oxygen molecule of the group

What is the frequency of the light with a wavelength of 4.90x10^-7 m
docker41 [41]

Answer: 6.12\times 10^{14} Hz

Explanation: Recall the formula for the speed of light is

c=\lambda v

where c is the speed of light,\lambda is the wavelength, and v is the frequency. Assuming this takes place in a vacuum, c=3.00\times 10^8 m/s. Now we can solve for frequency

c=\lambda v

3.00\times 10^8 = 4.90\times 10^{-7}\cdot v

v = \frac{3.00\times 10^8}{4.90\times 10^{-7}}

v =6.12\times 10^{14} (rounding to 3 sig figs)

Thus, the frequencyis 6.12\times 10^{14} Hz.

What is the difference between thermal energy and temperature?
igor_vitrenko [27]
The hotter an object is, the faster the motion of the molecules inside it. Thus, the heat of an object is the total energy of all the molecular motion inside that object. Temperature, on the other hand, is a measure of the average heat or thermal energy of the molecules in a substance.

A neutral atom of sodium (Na) has an atomic number of 11 and a mass number of 23. How many neutrons would be found in the nucleu
SCORPION-xisa [38]
<h3>Answer:</h3>

12 neutrons

<h3>Explanation:</h3>
  • A neutral atom is an atom that has no charge, which means it has no additional electrons or electrons removed from its energy levels.
  • An atom is made up of sub-atomic particles neutrons and protons found in the nucleus and electrons found in the energy levels.
  • The number of protons in the nucleus of a neutral atom is known as the atomic number.
  • In a neutral atom, the atomic number is equal to the number of electrons as protons are equal to the number of electrons.
  • The sum of protons and neutrons in the nucleus of an atom is known as the mass number of an atom.

Therefore;

Protons = Atomic number

Protons + neutrons = Mass number

Thus;

Neutrons = Mass number - protons or

                = Mass number - atomic number

In this case;

Atomic number = 11

Mass number = 23

Thus;

Neutrons = mass number - atomic number

               = 23 - 11

              = 12 neutrons

vagabundo [1.1K]

Explanation:

Since, aluminium chloride is an eye and skin irritant. Therefore, it is better to follow safety measures while dealing with such a chemical.

Hence, it is good to wear a lab coat while working in a laboratory and wear chemical resistant gloves so that our skin does not come in contact with the chemical.

Also, safety glasses will prevent the eyes if there is spurting of chemical.

Thus, we can conclude that chemical-resistant gloves, a lab coat, and safety glasses will prevent you from coming into contact with the given hazard.
