Which wave has a disturbance that is perpendicular to the wave motion?

Chemistry
2 answers:
Drupady [299]4 years ago
8 0

Answer:The correct answer is option B.

Explanation:

Transverse waves are the waves with oscillation vibrating perpendicular the propagation of the wave.

Whereas, Surface wave is the wave which travels across the surface of the earth.

Longitudinal wave is the wave in which medium vibrates in the same direction of the propagation of the wave.

vfiekz [6]

Answer:

C. Its oxidation number increases.

Explanation:

  • <em><u>Oxidation is defined as the loss of electrons by an atom while reduction is the gain of electrons by an atom</u></em>.
  • Atoms of elements have an oxidation number of Zero in their elemental state.
  • When an atom looses electrons it undergoes oxidation and its oxidation number increases.
  • For example, <em><u>an atom of sodium (Na) at its elemental state has an oxidation number of 0. When the sodium atom looses an electrons it becomes a cation, Na+, with an oxidation number of +1 , the loss of electron shows an increase in oxidation number from 0 to +1.</u></em>

Over [174]

Answer:

D

Explanation:

A synthesis reaction is a reaction in which two or more reactants combine to form a given product.

If we look closely at option D, you will notice that sulphur and oxygen combined together to form sulphur dioxide. That is a typical example of chemical synthesis.

Hence;

S + O2 ----->SO2 is a synthesis reaction.

Which statement about subatomic particles is true?
Kruka [31]

The correct statement about subatomic particles is Electrons are the subatomic particles with the smallest mass.

The mass of protons and neutrons which are considered as 1 unit of mass of atoms is approximately 1836 times the mass of the electron

\boxed {\boxed {\bold {Further ~ explanation}}}

Atoms are composed of 3 types of basic particles namely protons, electrons, and neutrons

The mass of this basic particle is expressed in units of atomic mass

This atomic unit uses the standard atomic mass, that is, the C-12 isotope

1 atom C-12 = 12 atomic mass units

1 atomic mass unit = 1/12 x mass 1 C-12 atom

1 unit of atomic mass = 1.66.10⁻²⁴

the mass of each basic particle in atomic mass units is:

electron mass = 9.11.10⁻²⁸

proton mass = 1.6726.10⁻²⁴

neutron mass = 1,675.10⁻²⁴

The proton mass is considered to be equal to 1 atomic mass unit and a neutron which is also considered to be equal to 1 atomic mass unit

The charge of 1 proton is equal to a charge of 1 electron but has a different sign

The proton is positively charged (+1), the electron is negatively charged (-1). and neutrons not charged (neutral)

For a charge of 1 electron = e = 1.66.10⁻¹⁹ coulomb

Whereas the neutron charge = 0

Let's look at the answer choices

  • 1. Protons are the only subatomic particles to have a charge.

This statement is wrong because in the nucleus there are electrons charged -

  • 2. Electrons are the subatomic particles with the smallest mass.

The statement is true because the mass of protons and neutrons which are considered as 1 unit of mass of atoms is approximately 1836 times the mass of the electron

  • 3. Neutrons orbit the nucleus of the atom.

This statement is wrong.

It can be explained by the Bohr atomic model, where electrons circulate the nucleus on a particular path so that electrons are not attracted to the nucleus.

  • 4. Subatomic particles all have the same mass

This statement is wrong because the mass of protons and neutrons is the same while the electron mass is smaller

So the correct statement about subatomic particles is Electrons are the subatomic particles with the smallest mass.
