What is the primary result of a fission
reaction?
(1) conversion of mass to energy
(2) conversion of energy to mass
(3) binding together of two heavy nuclei
(4) binding together of two light nuclei
Answer:
(1) conversion of mass to energy
Explanation:
Nuclear fission: In nuclear fission, an unstable atom splits into two or more smaller pieces that are more stable, and releases energy in the process. The fission process also releases extra neutrons, which can then split additional atoms, resulting in a chain reaction that releases a lot of energy.
The primary result of a nuclear fission reaction is the conversion of energy to mass.
What is nuclear fission reaction?Nuclear fission reaction is a reaction in which the nucleus of an atom splits into two or more smaller nuclei. The nuclear fission reaction produces gamma photons and releases a very large amount of energy even by the energetic standards of radioactive decay.Hence, option 2 is the answer.

Which of the following is an example of a decomposition reaction?
Answer:
B is a decomposition reaction
The chemical equation which represents decomposition reaction is 2 NaCl[tex]\rightarrow[/tex] 2 Na + Cl₂.
What is chemical equation?Chemical equation is a symbolic representation of a chemical reaction which is written in the form of symbols and chemical formulas.The reactants are present on the left hand side while the products are present on the right hand side.
A plus sign is present between reactants and products if they are more than one in any case and an arrow is present pointing towards the product side which indicates the direction of the reaction .There are coefficients present next to the chemical symbols and formulas .
The first chemical equation was put forth by Jean Beguin in 1615.By making use of chemical equations the direction of reaction ,state of reactants and products can be stated. In the chemical equations even the temperature to be maintained and catalyst can be mentioned.

CuSO4(s)
CuSO4(aq)
C5H12(l)
CO2(g)
Answer:
CuSO4(aq)
Explanation:
The aqueous form of copper sulfate will conduct electricity.
The Solid form will not be a good conductor.
C₅H₁₂ will not conduct electricity
CO₂ will not conduct electricity
Copper sulfate is an ionic compoundIn aqueous solutions or molten forms, ionic compounds can conduct an electric current using free mobile ions as carriers. This way, they are electrolytes. In solid state, the ions are arranged into a crystal lattice and will not conduct a current of electricity.Which best explains the difference between a monomer and a polymer?

When an egg is boiled in a pot of water on the stove, there is more than one kind of heat transfer. Heat is transferred from the stove to the pot directly since they are physically touching. Heat is also transferred from the pot to the egg, carried through the water.
Answer:
Stove → Pot = conduction, Pot → Egg = convection.
Explanation:
There are three ways in which heat is being transferred from one medium to the other and the means are; radiation, conduction and convection heat transfer.
Radiation is the process in which heat is being transferred through emission in form of electromagnetism. Conduction heat transfer Is the process in which heat is being transferred through contact that is two bodies touching each other. Convection heat transfer is the kind of heat that happens through gases.
Since the heat from the stove touching the pot is the conduction heat transfer.
After the water has been heated up, the gas from the water makes the convection heat transfer.

How does the quantum theory of atoms explain the nature of the emission-line spectrum of hydrogen?
Energy takes on discreet values, we notice that only certain values of energy are allowed hence the line spectrum of the hydrogen atom.
According to the Bohr model of the atom, energy levels within the atom is quantized. Energy quantization implies that energy occurs in discreet packets and do not take on intermediate values.
Because energy takes on discreet values, we notice that only certain values of energy are allowed hence the line spectrum of the hydrogen atom.

How many more valence electrons does this atom need to fulfill the Octet
Rule? (Urgent need help)
Answer: The octet rule is a bonding theory used to predict the molecular structure of covalently bonded molecules. According to the rule, atoms seek to have eight electrons in their outer—or valence—electron shells. Each atom will share, gain, or lose electrons to fill these outer electron shells with exactly eight electrons.

What element is in period 6 with 2 valence electrons?
Answer:
Barium
Explanation:
I think that's the answer
The element in period 6 with 2 valence electrons is Barium.
The periodic table has been organized into periods and groups. The period is in an horizontal arrangement while group is vertical arrangement. The elements that can be found in period 6 are Beryllium, Magnesium, Calcium, Strontium, Barium etc. Elements in the same group have the same number of valence electrons. This means that elements in group 2 have 2 valence electrons. Barium possess two valence electrons because it is in group 2 and it is also in period 6. Therefore, the element in period 6 with 2 valence electrons is Barium.Learn more at: https://brainly.com/question/24089206?referrer=searchResults
when hydrogen atom absorbs a photon, and an electron moves level 1 to level 2, what happens to the energy of the atom?
Answer:
When an electron is hit by a photon of light, it absorbs the quanta of energy the photon was carrying and moves to a higher energy state. One way of thinking about this higher energy state is to imagine that the electron is now moving faster, (it has just been "hit" by a rapidly moving photon).
