Answer:
How quickly an object accelerates is directly related to the Mass of the object and the size of the Force applied to it.
Explanation:
Acceleration is directly proportional to force and inversely proportional to mass. This means that if you get pushed, the harder you are pushed, the faster you'll move (accelerate).
What is the relationship between force and acceleration?
Newton's second law shows that there is a direct relationship between force and acceleration. The greater the force that is applied to an object of a given mass, the more the object will accelerate. For example, doubling the force on the object doubles its acceleration.
What is the relationship between mass and acceleration?
The acceleration of an object depends directly upon the net force acting upon the object, and inversely upon the mass of the object. As the force acting upon an object is increased, the acceleration of the object is increased. As the mass of an object is increased, the acceleration of the object is decreased.

Explain what is meant by the term "excited state" as it applies to an electron. Is an electron in an excited state higher or lower in energy than an electron in the ground state? Is an electron in an excited state more or less stable than an electron in the ground state?
Answer:
Excited state of an electron is the state attained by an electron after it has absorbed energy and it moves further from the nucleus.
an electron is at higher energy when excited and at lower energy when at ground state.
an excited electron is less stable due to the decrease in the nuclear force of attraction and the grounded electron is more stable due to it's close distance to the nucleus.
An electron in excited state has its electron present in higher energy level while an electron in ground state is present in lower energy level.
What is an energy level ?Electrons present in an atom revolve in different orbits which are stationary states and are also called as energy levels. The energy levels are numbered as integers which are also called as principal quantum numbers.
Energy of the stationary state is given as E= -R
1/n² where R
is the Rydberg's constant. When an electron is excited, and it moves from lower to higher energy levels there is absorption of energy, while when it moves from higher energy level to lower energy level it radiates or gives out energy in the form of radiation.
They can also be defined as the distances between electron and nucleus of an atom . Electrons present in K energy level have least energy .Energy level diagrams are studied to understand nature of bonding , placement of electrons in orbits and and elemental behavior under certain conditions.

Derive names for common types of inorganic compounds using a systematic approach
Nomenclature, a collection of rules for naming things, is important in science and in many other situations. This module describes an approach that is used to name simple ionic and molecular compounds, such as NaCl, CaCO3, and N2O4. The simplest of these are binary compounds, those containing only two elements, but we will also consider how to name ionic compounds containing polyatomic ions, and one specific, very important class of compounds known as acids (subsequent chapters in this text will focus on these compounds in great detail). We will limit our attention here to inorganic compounds, compounds that are composed principally of elements other than carbon, and will follow the nomenclature guidelines proposed by IUPAC. The rules for organic compounds, in which carbon is the principle element, will be treated in a later chapter on organic chemistry.
Ionic Compounds
To name an inorganic compound, we need to consider the answers to several questions. First, is the compound ionic or molecular? If the compound is ionic, does the metal form ions of only one type (fixed charge) or more than one type (variable charge)? Are the ions monatomic or polyatomic? If the compound is molecular, does it contain hydrogen? If so, does it also contain oxygen? From the answers we derive, we place the compound in an appropriate category and then name it accordingly.
Compounds Containing Only Monatomic Ions
The name of a binary compound containing monatomic ions consists of the name of the cation (the name of the metal) followed by the name of the anion (the name of the nonmetallic element with its ending replaced by the suffix –ide). Some examples are given in Table 3.5.2 .
Table 3.5.1 : Names of Some Ionic Compounds
NaCl, sodium chloride Na2O, sodium oxide
KBr, potassium bromide CdS, cadmium sulfide
CaI2, calcium iodide Mg3N2, magnesium nitride
CsF, cesium fluoride Ca3P2, calcium phosphide
LiCl, lithium chloride Al4C3, aluminum carbide
Compounds Containing Polyatomic Ions
Compounds containing polyatomic ions are named similarly to those containing only monatomic ions, except there is no need to change to an –ide ending, since the suffix is already present in the name of the anion. Examples are shown in Table 3.5.2 .
Table 3.5.2 : Names of Some Polyatomic Ionic Compounds
KC2H3O2, potassium acetate (NH4)Cl, ammonium chloride
NaHCO3, sodium bicarbonate CaSO4, calcium sulfate
Al2(CO3)3, aluminum carbonate Mg3(PO4)2, magnesium phosphate

Naming Ionic Compounds
Name the following ionic compounds, which contain a metal that can have more than one ionic charge:
Fe2S3
CuSe
GaN
CrCl3
Ti2(SO4)3
Solution
The anions in these compounds have a fixed negative charge (S2−, Se2− , N3−, Cl−, and SO2−4 ), and the compounds must be neutral. Because the total number of positive charges in each compound must equal the total number of negative charges, the positive ions must be Fe3+, Cu2+, Ga3+, Cr4+, and Ti3+. These charges are used in the names of the metal ions:
iron(III) sulfide
copper(II) selenide
gallium(III) nitride
chromium(III) chloride
titanium(III) sulfate

Which terms represents the fixed proportion of elements in a compound
Answer:
Protons
Explanation:
I'm not exactly sure if this is what your question, but the number of protons is what makes an atom that atom. If you change the number of proton it is now a different atom. You change the number of electrons and get an ion or change the number of neutrons and get an isotope but you can't change the number of protons as you would be changing the elemnt.

Which statement desrcribes an intensive property of matter? -it is the same for every sample of a single substance -it depends on how a substance was formed -it is the same for every sample of every substances -it depends on the amount of substances present
Answer:
The statement which describes an intensive property of matter is - :
it is the same for every sample of a single substance.
Explanation:
It is the same for every sample of a single substance. -: Since a substance 's intense property does not depend on either mass or volume, it is the same for each sample of a single substance. Hence , this statement is correct .It depends on how a substance was formed -: Intensive property do not depend upon the amount of the substance or the formation of the sample . Therefore this statement ifs wrong about intensive property .It is the same for every sample of every substances -: This is not possible to be for every sample of the substance , a every substance have different qualities. Hence this statement is also incorrect.it depends on the amount of substances present -: This is the characteristic of a extensive property of matter that relies on the amount of the material/substance. This assertion is, therefore, not valid.Hence , the correct option is A (it is the same for every sample of a single substance).

what is biogas, biomass and biodigester
Answer:
Biogas is a type of biofuel that is naturally produced from the decomposition of organic waste. When organic matter, such as food scraps and animal waste, break down in an anaerobic environment (an environment absent of oxygen) they release a blend of gases, primarily methane and carbon dioxide.
Explanation:
Biomass is renewable organic material that comes from plants and animals. ... Biomass contains stored chemical energy from the sun. Plants produce biomass through photosynthesis. Biomass can be burned directly for heat or converted to renewable liquid and gaseous fuels through various processes.biodigester is like a mechanical stomach. It is fed with organic material, which is broken down (decomposed) by micro-organisms (bacteria) is an oxygen-free (anaerobic) environment to produce a renewable energy called biogas (methane and carbon dioxide) and other material that is mainly used as fertilizer.
Explanation:
Biogas is a type of biofuel that is naturally produced from the decomposition of organic waste.
Biomass is plant or animal material used for energy production, or in various industrial processes as raw substance for a range of products.
A Biodigester simply means a tank which digests organic material biologically. In this sense, the FilterPod is a biodigester. However, many people think of a biodigester as a tank which digests, anaerobically, without air, organic material and produces methane gas for cooking, lighting and heating ect.
