Answer:
Thermal Energy: It refers to some distinct physical concepts, such as the internal energy of a system or heat or sensible heat. And these mode of transfer of heat include, convection, conduction and radiation which I have explained below.
Convection: This is a mode of transfer of heat in which bulk movement of molecules within fluids takes place, as these molecules move the heat obtained by each of the molecules will reach the new location.
Radiation: Radiation is the emission or transmission of energy in the form of waves or particles through space or through a material medium
Conduction: Conduction is the transfer of internal energy by microscopic collisions of particles and the movement of electrons within an object.
If the atomic number of an element is 8 and the mass number is 16, the number of neutrons in an atom of that element is what? (show work)
Answer:
8.
Explanation:
Atomic number tells us the number of protons in an element. Mass number is the total amount of mass in an atom, and it comes from the sum of the mass of protons and neutrons, which are both considered to have a mass of 1 amu.
If the total mass is 16amu and 8amu comes from the 8 protons, the remaining mass comes from neutrons.
16 - 8 = 8

why is respiration considered an exothermic process
Answer:
Respiration is considered as exothermic reaction because energy is released in this process. Glucose combines with oxygen present in our cells to form carbon dioxide and water along with energy.
Explanation:
Good Luck!
Respiration is considered as an exothermic reaction because, in the respiration process, oxidation of glucose takes place which produces a large amount of heat energy stored in the form of ATP. This is shown in the following chemical equation C 6

a decomposition reaction in which a metal is reduced
an acid-base neutralization reaction to produce oxygen gas
a displacement reaction involving two metals
a combustion reaction involving burning a metal in oxygen
Answer:
decomposition
Explanation:
the reactants turn into two different products, thus the reaction is decomposition.
AB -> A + B
Answer:
A: a decomposition reaction in which a metal is reduced
Explanation:
HgO is actually the metal Mercury and in the equation Mercury is being decomposed into the elements Hg and O. (the element for Mercury and Oxygen) So the equation they give you is a decomposition.

Does anyone knows how to solve this??
Answer:
²⁴³₉₅Am --> ²³⁹₉₃Np + ⁴₂He
Explanation:
In alpha decay;
The mass number decreases by 4
Atomic Number decreases by 2
Mass Number = 243 - 4 = 239
Atomic Number = 95 - 2 =93
Element = Neptunium (Np)
Equation for the decay is given as;
²⁴³₉₅Am --> ²³⁹₉₃Np + ⁴₂He

In a chemical reaction*
1 point
The atoms of the reactants unbond, rearrange, and then rebond to form the products
Some atoms disappear while others multiply to form the products
The atoms of the reactants always stay together to form the products
New atoms are formed which combine to make the products
Answer:
1st one is correct
The atom of the reactants unbound , rearrange, and then rebond to form the product
hope it helps
In a chemical reaction, the atoms of the reactants unbond, rearrange, and then rebond to form the products. Therefore, option A is correct.
What is chemical reaction ?Chemical reaction, the transformation of one or more chemicals the reactants into one or more distinct compounds, the products. Chemical elements or chemical compounds make up substances.
Combustion reaction, decomposition reaction, neutralization reaction, redox reaction, precipitation or double-displacement reaction, and synthesis reaction are some of the numerous types of reactions.
In a chemical reaction, bonds between molecules of the reactant are broken and new bonds between molecules of the product are established to create a new substance.
A chemical equation is nothing more than a mathematical statement that represents how reactants form products.
Thus, option A is correct.

White arctic hares blending in with the white snow in their environment is an example of what type of camouflage?
A. hiding
B. protective resemblance
C. mimicry
D. protective coloration
Answer:
The answer to your question is A.
D. Protective coloration. Protective coloration, also known as "crypsis," is a defense mechanism used by animals to avoid detection by predators or prey.
An illustration of protective coloration, which is a sort of camouflage, is how white arctic hares blend in with the white snow around them. Animals use protective coloration, commonly referred to as "crypsis," as a defensive strategy to evade being seen by predators or prey.
In this instance, the white arctic hares' fur is the same shade as that of their snowy environment. Their chances of survival are increased by this merging, which enables them to remain unnoticed and effectively hidden from predators like polar foxes or birds of prey. They have a better chance of escaping or avoiding detection when they are well-camouflaged, making it difficult for predators to see them against the white background.
