Which of the following is an example of a decomposition reaction?
Answers
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.

What is atomic mass made of?
Answers
Answer:
Together, the number of protons and the number of neutrons determine an element's mass number: mass number = protons + neutrons. If you want to calculate how many neutrons an atom has, you can simply subtract the number of protons, or atomic number, from the mass number.

How do HOT AIR BALLOONS work when ascending and descending explain in terms of gas behavior?
Answers
Answer: Animation: Burning gas makes the air inside the balloon less dense, producing an upward force or lift. 1) A hot air balloon stays on the ground (or descends) when the air inside it is too cool. ... 3) When the air is hotter still, the balloon rises because the lift force is greater than the weight.

when hydrogen atom absorbs a photon, and an electron moves level 1 to level 2, what happens to the energy of the atom?
Answers
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).

What element is in period 6 with 2 valence electrons?
Answers
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

Answer:
c
Explanation:
Which of the following elements is the least reactive metal? Sodium, Rubidium, Chlorine, and Magnesium.
Answers
Sodium and Rubidium are in group 1 of the periodic table and Magnesium is in group 2.
Group one metals are more reactive than group two because it is harder for the group two metals to lose their 2 valence (outer most) electrons.
As you go down group 1 there is an increase in the reactivity this is because as you go down there is an increase in the atomic radius which leads to more shielding. This weakens the electrostatic forces of attraction making it easier to lose the outermost electrons, therefore they are more reactive.

Magnesium

Is iron rusting a chemical reaction? Explain why or why not.
Answers
Answer: Yes- Rusting is an oxidation reaction. The iron reacts with water and oxygen to form hydrated iron(III) oxide, which we see as rust. Iron and steel rust when they come into contact with water and oxygen – both are needed for rusting to occur. Rusting is an example of a chemical change. A chemical property describes the ability of a substance to undergo a specific chemical change. A chemical property of iron is that it is capable of combining with oxygen to form iron oxide, the chemical name of rust.

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.
Answers
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.
