Explanation:
1. subatomic particles.
2.proton, electron and neutron
3.The atomic mass of an element is actually the sum of the MASSES of protons and neutrons in AN atom of that element
4.An element's atomic number is equal to the number of protons in the nuclei of any of its atoms
5. Number of Protons = Atomic Number
Number of Electrons = Number of Protons = Atomic Number
Number of Neutrons = Mass Number - Atomic Number
For krypton:
Number of Protons = Atomic Number = 36
Number of Electrons = Number of Protons = Atomic Number = 36
Number of Neutrons = Mass Number - Atomic Number = 84 - 36 = 48
6. electron, lightest stable subatomic particle known. It carries a negative charge of 1.602176634 × 10−19 coulomb, which is considered the basic unit of electric charge. The rest mass of the electron is 9.1093837015 × 10−31 kg
7.The center of the atom is called a nucleus
8. Negatively charged particles are found in multiple layers outside the nucleus of the atom. These particles are called electrons, and they orbit in various energy levels around the atom's nucleus.
9. A charged particle is also called an ion
The balanced equation is
<span>2 C6H6 +15 O2 = 12 CO2 + 6 H2O </span>
<span>the ratio between C6H6 and CO2 is 2 : 12 </span>
<span>moles CO2 produced = 7.94 x 12 / 2 =47.6</span>
Party realignment a shifting of party alliances within the electorate.
<h3 /><h3>What is party alliances?</h3>
An electoral alliance is a grouping of political parties or individuals who get together primarily to run for office in elections. It is also referred to as a bipartisan electoral accord, electoral pact, electoral agreement, electoral coalition, or electoral bloc.
Founded in 2019, the Alliance Party is a centrist American political party. It is connected to the American Party of South Carolina, the Minnesota Independence Party, the Connecticut Independent Party, and the Florida Reform Party.

An element or compound will react with oxygen and will produce carbon dioxide, water, and sometimes carbon (if it is an incomplete combustion).
<span>Petroleum and biomass are burned in combustion reactions, which liberate energy stored in chemical bonds. This is chemical energy. In contrast, nuclear energy comes from the conversion of mass into energy when an nuclear reaction occurs. Geothermal energy comes directly from heat sources underground, with no chemical or nuclear reactions.</span>
