What is energy?Energy is the quantifiable quality that is transferred to a body or a physical system and is noticeable in the performance of work as well as in the form of heat and light.
Energy is a conserved resource; according to the law of conservation of energy, energy can only change its form; it cannot be created or destroyed.
Primary energy sources come in a variety of forms, such as nuclear energy and fossil fuel energy.

How do particles in the most rigid state of matter move? A. They stay close together and vibrate in place B. They move freely from one place to another within their container C. They stay close together and slip past one another D. They bounce off one another and the slides of their container
Answer:
A: they stay close together and vibrate in place
Explanation:
assuming the most rigid state would be a solid, thats how particles of a solid move
Answer:
A
Explanation:
particles in the most rigid state (soilds) vibrate on the spot
each particle is attached to several others so they cant move freely
Hydrogen gas caught fire quickly in the Hindenberg accident. In comparison, neon gas and helium gas are nonreactive. This is why helium is safe for aircraft and neon is safe for electrical signs. Which statement best explains why helium and neon have similar chemical properties?
Answer:
Helium and Neon have similar chemical properties because both of them completely fill the outer shell of their atoms' electrons, so there is nothing to share with other atoms, neither with the same element nor with any other element.
Explanation:
Helium and Neon are both noble gases . As elements react, their atoms, by losing, acquiring, or sharing electrons, complete their outer shells. Noble gas atoms already have full outer shells, so there is no tendency for them to lose, gain, or share electrons. There are incomplete outer shells of atoms of group 1 and 7 elements (so they are reactive)
Chemical properties of HELIUM and NEON -:
In group 8(or 0) of the periodic table, on the far right side, the Noble Gases are contained. Helium, neon, argon, krypton, xenon and radon are their names. They are extremely colourless and unreactive. They do not form bonds, so they still remain as single (monatomic) atoms. There is very little chemical reactivity in them.Hence, helium and neon have similar chemical properties as they are the most stable due to having the maximum number of valence electrons their outer shell can hold.

A solid rubber ball with a mass of 5.9 grams sank in water. A hollow rubber ball with the same mass floats in water. Explain why this might be. Please answer ASAP!
Answer:
The hollow ball is more buoyant than the solid ball.
Explanation:
The hollow ball will float while the solid ball sinks because the volume of water displaced by the hollow ball is more than that displaced by the solid ball.
An object floats when it displaces a volume of water equal to its weight. A solid ball is more compact, and hence, does not displace a lot of water when dropped into a bowl full of water. On the other hand, the hollow ball will have a larger curved surface area, since it has no fill. This will make it displace a larger volume of water and hence make it float.

Jaden listed the similarities of using coal, natural gas, and petroleum to generate electricity. Coal, natural gas, and petroleum: – use turbines – require heat – convert electrical energy to kinetic energy – produce pollution in the form of smoke Which best describes Jaden’s mistake? Only coal-fired power plants use turbines. Power plants do not require heat. Kinetic energy is converted to electrical energy. Coal does not produce pollution.
Answer:
The answer is C. Kinetic Energy is converted to electrical energy
Explanation:
Just took the test
Electric energy is converted to kinetic energy is the mistake that Jaden made in this scenario.
What is Energy?This is defined as the capacity and ability to do work and examples include kinetic, electrical etc.
The kinetic energy through the movement of water by the wind is what powers the turbine to become an electric energy and not electrical energy being converted to kinetic energy.

10 points
Answer:
12 atoms
but u said there are 10 pts but only 5 are there
Answer:
[tex]6.02 \times {10}^{24} \: atoms[/tex]
Step-by-step explanation:
Number of atoms of Al = Number of moles of Al × Avogadro constant
[tex] = 4 \times 6.02 \times 10 ^{23} [/tex]
[tex] = 2.408 \times 10 ^{24} \: atoms[/tex]
Number of atoms of O = Number of moles of O × Avogadro constant
[tex] = 6 \times 6.02 \times {10}^{23} [/tex]
[tex] = 3.612 \times 10 ^{24} \: atoms[/tex]
Total number of atoms
[tex] = 2.408 \times {10}^{24 } + 3.612 \times {10}^{24} [/tex]
[tex] = 6.02 \times {10}^{24} atoms[/tex]

Identify the independent and dependent variables in the following experiment: A scientist grew bacteria on the gel in her lab. She wanted to find out if the bacteria would grow faster on gel A or gel B. She placed a few bacteria on gel A and a few on gel B. After 24 hours, she observed how many bacteria were present on each type of gel.
The dependent was before she started changing them and the independent variable is the process of them changing.
The independent variable is the type of gel, the dependent variable is the growth rate of the bacteria.
Dependent variables and independent variables are terms used in mathematics, statistics, and other experimental sciences. Each of them is characterized by:
Dependent variable: Its value is the result of a series of variable conditions that are modified on purpose.Independent variable: These are variables that are modified on purpose to show a phenomenon and obtain a result in a dependent variable.According to the above, in the situation presented, the independent variable is the type of gel because two types of gel are used, to obtain different results according to the characteristics of each gel.
Additionally, the dependent variable of this experiment is the growth rate of the bacteria under different conditions (gel A and gel B).

what affects the rate at which acid rain reacts with a statue
The thing that affects the rate at which acid rain reacts with a statue is the concentration of sulfur dioxide and carbon dioxide in the environment.
What is Acid rain?Acid rain may be defined as a type of precipitation on the surface of the earth that involves a significant amount of acids like nitric acid, sulphuric acid, and carbonic acid due to the heavy concentration of nitrous oxide, carbon dioxide, and sulfur dioxide in the environment.
This high concentration of acids in acid rain generally reacts with metals and corrodes them. They permanently lose the actual shine of marble, statues, buildings, etc.
The concentration of these acids typically affects the rate at which acid rain reacts with a statue. If there is a high concentration, it highly influenced the property of statues.
Therefore, the thing that affects the rate at which acid rain reacts with a statue is the concentration of sulfur dioxide and carbon dioxide in the environment.
