Answer:
C
Explanation:
Fission reactions run out of control, while chemical reactions are controlled. :)
"Chemical reactions are depends on electrons while fission depends on protons. In fission , there is no any effect of temperature while in case of chemical reaction rate of reaction will be affected."
What is chemical reaction?
The type of reaction in which more than one molecule get combined and form a different kind of product then such type of reaction can be considered as chemical reaction.
What is Fission reaction?
Fission is the breaking of a heavy nucleus into lighter nuclei, while fusion is the joining of nuclei to create a larger and heavier nucleus.

Describe the nucleus of the
atom.
Answer:
The nucleus of atom is composed of two subatomic particles that each have charges.
Protons, which are positively charged particles.Neutrons, which are neutrally charged particles.Both reside in the nucleus of an atom. The amount of protons and neutrons (Electrons can to) is what helps us identify each atom apart. Electrons are NOT in the nucleus of atom but orbit it in outer layers called orbitals.

When asked why a chlorine atom gains one electron to form an anion with a 1- charge, a classmate answered, "Because noble gas configurations are stable." Is this statement generally true?
Noble gases have the maximum number of electrons in their outer shell. The statement made by the student about the stability of noble gases is generally true.
It is true that noble gases are stable elements. This can be attributed to the fact that they have the complete number of elements in their outer shell. That is why they hardly participate in any reactions. The chlorine atom receives an electron from a donor element and attains a negative charge. When two chlorine atoms bond covalently, they share electrons and thus attain the noble state configuration.Learn more here:

____ are the forces of attraction between positive metal ions and the valence electrons that surround them.
The forces of attraction that exists between positive metal ions and their surrounding valence electrons is called: metallic bonds.
A chemical bond can be defined as the forces of attraction that exists between ions, crystals, atoms or molecules and they are mainly responsible for the formation of all chemical compounds.
In Chemistry, there are different types of chemical bonds and these are:
Hydrogen bonds.Covalent bonds.Ionic bonds.Metallic bonds.A metallic bond can be defined as the forces of attraction that exists between positive metal ions and their surrounding valence electrons.
This ultimately implies that, metallic bond are peculiar to positively charged metals but not negatively charged metals or non-metals.

Which statement best describes how inflating a balloon is evidence of matter?
O It changes color and length.
o It changes mass and temperature.
o It changes size and shape.
O It changes texture and width.
Answer:
It changes size and shape
Explanation:
Proving Air Is Matter
One way to prove that air is made of matter is to blow up a balloon. Before you add air into the balloon, it is empty and shapeless. When you puff air into it, the balloon expands, so you know it is filled with something—air is taking up the space.

An atom that gains one extra electron forms an ___________with a 1- charge.
Explanation: When an atom gains/loses an electron, the atom becomes charged, and is called an ion. Gaining an electron results in a negative charge, so the atom is an anion.

How are chemical equations balanced?
Answer:
According to the law of conservation of mass, when a chemical reaction occurs, the mass of the products should be equal to the mass of the reactants. A balanced chemical equation occurs when the number of the atoms involved in the reactants side is equal to the number of atoms in the products side

How didMendeleev feel about Russian science education when he came back from Germany?
While he was researching and writing that book in the 1860s, Mendeleyev made the discovery that led to his most famous achievement. He noticed certain recurring patterns between different groups of elements and, using existing knowledge of the elements' chemical and physical properties, he was able to make further connections. He systematically arranged the dozens of known elements by atomic weight in a grid-like diagram; following this system, he could even predict the qualities of still-unknown elements. In 1869, Mendeleyev formally presented his discovery of the periodic law to the Russian Chemical Society.
Hope This is Ok :)
A new element has been discovered. Scientists are trying to determine where it should it be placed on the periodic table. In order to do this they must determine the following about the element:
Elements are placed in order on the periodic table based on their atomic number, how many protons they have. In a neutral atom, the number of electrons will equal the number of protons, so we can easily determine electron number from atomic number.

Determinar el valor positivo de “m” para que la ecuación: x(x+2)=4mx−8 ; tenga una raíz que sea el doble de la otra.
El valor positivo de [tex]m[/tex] para que la ecuación [tex]x\cdot (x+2) = 4\cdot m \cdot x - 8[/tex] tenga una raíz que sea el doble de la otra es 2.
De acuerdo con el enunciado de esta pregunta, debemos encontrar un valor de [tex]m[/tex] a partir del siguiente sistema de ecuaciones:
[tex]r\cdot (r+2) = 4\cdot m \cdot r -8[/tex] (1)
[tex]2\cdot r \cdot (2\cdot r + 2) = 4\cdot m \cdot (2\cdot r) - 8[/tex] (2)
Ahora simplificamos el sistema de ecuaciones:
[tex]r^{2}+2\cdot r = 4\cdot m\cdot r - 8[/tex] (1b)
[tex]4\cdot r^{2}+4\cdot r =8\cdot m\cdot r - 8[/tex] (2b)
Despejamos [tex]m[/tex] en cada expresión, lo eliminamos y resolvemos el polinomio resultante:
[tex]\frac{r^{2}+2\cdot r + 8}{4\cdot r} = \frac{4\cdot r^{2}+4\cdot r +8}{8\cdot r}[/tex]
[tex]r^{2}+2\cdot r + 8 = 2\cdot r^{2}+2\cdot r +4[/tex]
[tex]r^{2}-4 = 0[/tex]
[tex]r^{2} = 4[/tex]
[tex]r = \pm 2[/tex]
Finalmente, determinamos el valor de [tex]m[/tex], que al ser positivo, debemos utilizar [tex]r = 2[/tex]:
[tex]m = \frac{2^{2}+2\cdot 2 + 8}{4\cdot 2}[/tex]
[tex]m = 2[/tex]
El valor positivo de [tex]m[/tex] para que la ecuación [tex]x\cdot (x+2) = 4\cdot m \cdot x - 8[/tex] tenga una raíz que sea el doble de la otra es 2.

why does magnesium in an aqueous solution of magnesium chloride conduct electricity but solid magnesium chloride does not?
Answer:
Delocalized electrons
Explanation:
Magnesium Chloride is an ionic compound, so its lattice structure prevents the flow of electrons. However, when you convert the ionic compound into an aqueous solution it allows movement of electrons/ions due to the breakdown of the molecular forces which make it conductible. In short, Ionic compounds as a solid are not conductible but they are in an aqueous form.

Answer:
4-ethyl-6-methyl-3-heptene
Explanation:
Longest chain is seven long so it is heptane
But there is a double bond, so that becomes heptene
The double bound starts on the third carbon, so it is 3-heptene (this tells us where the double bond is)
Now we just got to do the substituents!
There is a ethyl group of the fourth carbon and then a methyl group on the sixth!
Ergo, 4-ethyl-6-methyl-3-heptene
