What is wrong with the following explanation of an experiment? When it was heated, the sample of carbon decomposed.
Drupady [299]
"Carbon" is an element. It is found in the fourth group of the periodic table, and it is a stable element. This means that it can not be decomposed via heating, because if an element were to break down, it would release its subatomic particles. The explanation was probably one used to describe the thermal decomposition of a compound into smaller compounds.

A 60 and N net force is applied to a 12 kg box which is the acceleration of the box?
GarryVolchara [31]

The relation between force and mass and acceleration is

Force = mass X acceleration

The SI unit will be

Force = Newton

mass =kg

acceleration=\frac{m}{s^{2} }

thus

acceleration = \frac{Force}{mass}

putting values

acceleration=\frac{60 N}{12kg}=5\frac{m}{s^{2} }

Thus the acceleration will be

5\frac{m}{s^{2} }

Describe the atomic theory of atoms
alexandr402 [8]

Answer: Below

                   |

                   |

                   ^

Explanation:

The atomic theory is that all matter is made up of tiny units or particles called atoms. This theory describes the characteristics, structure and behavior of atoms as well as the components that make up atoms. Furthermore, the theory states that all elements are made up of identical atoms.

The atomic theory is a theory in the study of chemistry that states atoms are the building blocks of matter. Atoms contain protons, neutrons and electrons. Protons, which have a positive charge, and neutrons are found in the nucleus of the atom. Electrons, which have a negative charge, orbit the nucleus.

According to the atomic theory, all elements contain atoms. The difference is the number of protons, electrons and neutrons in that atom. For instance, hydrogen contains one proton and one electron but no neutrons. Oxygen, on the other hand contains eight protons, electrons and neutrons. The difference in protons, electrons and neutrons determines the stability and the other properties of any particular element. These elements are grouped according to their atomic masses, which depend on the number of protons and neutrons in each of the atoms. Because oxygen has more protons and neutrons than hydrogen, it has a higher atomic mass.
