Answer:
Carbon has 4 valence electrons
Explanation:
The valence electrons are those found in the last energy level of the atom.
They are responsible for the interaction between atoms,
they can form bonds.
Let's see the electronic configuration of carbon.
The atomic number of C is 6 (Z=6)
To know the number of valence electrons that we have we count in the last energy level of the atom.
The last energy level of carbon is 2 and we 4 electrons is this level.
So carbon has 4 valence electrons.
Final answer:
Carbon, as an element from Group 14 of the periodic table, has four valence electrons. These electrons are the ones available for bonding and are located in its outermost shell.
Explanation:
Carbon belongs to Group 14 in the periodic table and has four valence electrons. These are the electrons that are available for bonding. Elements in Group 14 have four electrons in their outermost shell because the s and p sublevels can hold up to four electrons. For example, in the case of carbon, its electron configuration is 1s22s22p2 which clearly shows the four valence electrons in the outermost shell (the 2s and 2p orbitals).

Answers
Explanation:
1) The conservation of energy is a universal principle: energy is neither created nor destroyed. This is the first law of thermodynamic.
2) Mass conservation is another universal principle: mass is neither created nor destroyed. This principle is the base of the stochiometry: thas mass of the reactans equal the mass of the products. Another consequence, since the atoms are not transformed in the chemical reactions, is that the number of each kind of atoms in the reactants equal the number of the same kind of atoms in the products.
3) The third principle is the conservation of charge. Also, charge is neither created nor destroyed. The electrons gained/lost by one species are lost/gained by other species. So, when one atom or molecule is oxidized other is reduced.

The sample that is a pure substance is:A. a test tube of zinc oxide.
What sample is a pure substance?
A pure substance consists of only one type of substance with uniform properties throughout. In this case, a test tube of zinc oxide would be a pure substance. Zinc oxide (ZnO) is a chemical compound made up of zinc (Zn) and oxygen (O) atoms in a fixed ratio. It has a specific chemical formula and a consistent composition, making it a pure substance.
On the other hand:
B. A container of zinc and oxygen would be a mixture since it contains two different substances, zinc and oxygen, in their elemental forms.
C. A flask of pond water is a mixture because it contains a combination of different substances, such as water, dissolved minerals, microorganisms, and organic matter.
D. A jar of soil is also a mixture since it consists of a combination of various components, including minerals, organic matter, water, air, and possibly microorganisms.
Therefore, the correct answer is A. a test tube of zinc oxide, which represents a pure substance.

A transversewave is a wave is a wave in which the particles in the medium oscillate in a direction that is perpendicular or at 90 degrees to the direction in which the wave propagates. Light waves or electromagnetic waves are a good example of transverse waves. When an electromagnetic wave propagates, the medium in which it propagates vibrates in a direction perpendicular to the direction of travel.
A longitudinal wave is a wave in which the particles of the medium oscillate in a direction parallel to the direction in which the wave is travelling. Sound waves are good examples of longitudinal waves. When sound propagates, the particles of the medium which it travels through will vibrate in the direction in which the wave is travelling.
Similarities
- Both transverse and longitudinal waves carry energy.
- Both transverse and longitudinal waves obey the wave equation.
- Both transverse and longitudinal waves show behavior such as refraction, reflection, absorption, diffraction, etc.
Differences
The main difference is that for longitudinal waves, the particles in the medium will vibrate in the direction of the wave and that for transverse waves, the motion of the particles in the medium is in a direction perpendicular to the direction of propagation of the wave.

Answer: The number of moles that initially occupied a 250ml container remains the same when it occupied 750ml container but they are freer because the 750ml container is bigger and has more space. So the gases now occupied more space and their movement is less curtailed unlike when they were in 250ml container
