They bring oxygen into our bodies (called inspiration, or inhalation) and send carbon dioxide out (called expiration, or exhalation). This exchange of oxygen and carbon dioxide is called respiration.

Which part of atomic structure is responsible for the reactivity of atoms?
The electrons present in the valence shell of an atom are responsible for the reactivity of atoms.
What is an atom?An atom is defined as the smallest unit of matter which forms an element. Every form of matter whether solid,liquid , gas consists of atoms . Each atom has a nucleus which is composed of protons and neutrons and shells in which the electrons revolve.
The protons are positively charged and neutrons are neutral and hence the nucleus is positively charged. The electrons which revolve around the nucleus are negatively charged and hence the atom as a whole is neutral and stable due to presence of oppositely charged particles.
Atoms of the same element are similar as they have number of sub- atomic particles which on combination do not alter the chemical properties of the substances.

If a sample of air in a school container was heated, would the percentage of oxygen in the air increase, decrease, or remain unchanged?
Answer:
increase
Explanation:
Let's suppose we have a sample of air in a closed container. We heat the container and we want to predict what would happen to the pressure.
According to Gay-Lussac's law, the pressure of a gas is directly proportional to its absolute temperature.
Thus, if we increased the temperature of the air by heating it, its pressure would increase.
If a sample of air in a closed container was heated, the total pressure of the air would increase.

Would an alkaline earth metal make a good replacement for tin in a tin can?
Answer:
Definitely not. This is because the alkaline earth metal [basically group 2 elements] are reactive and will react with the contents of the can, contaminating it.
No, alkaline earth metals would not be a good replacement for tin in a tin can because alkali from alkaline earth metals react with tin and release hydrogen.
What are alkaline earth metals?Alkaline earth metals are present in group 2 of the periodic table. They are beryllium (Be), magnesium (Mg), calcium (Ca), strontium (Sr), barium (Ba), and radium (Ra).
They are called alkaline earth metals because their hydroxide and oxides are highly alkaline. Their metal oxides are found in the earth's crust.
These metals have 2 electrons in their outer shell, and they are highly reactive, so they will react with the tin in a tin can.
Thus, alkali from alkaline earth metals react with tin and generate hydrogen, hence they would not make an acceptable replacement for tin in a tin can.

when an electron is acquired by a neutral atom, the energy change is called
Answer:
when an electron is acquired by a neutron atom, the energy change is called its electron affinity
When an electron is added to a neutral atom to create a negative ion, the energy of the atom changes (in kJ/mole). This is how electron affinity is defined. Alternatively put, the possibility of the neutral atom receiving an electron.
What is electron affinity ?The amount of energy released when an electron binds to a neutral atom or molecule in the gaseous state to produce an anion is known as the electron affinity of an atom or molecule.
Although there is a slight distinction between the two, electron gain enthalpy is occasionally also referred to as electron affinity. The amount of energy released when an electron is added to a single gaseous atom is known as the electron gain enthalpy.
The amount of energy released when an atom receives an additional electron is known as its electron affinity. The gaseous state is when electron affinities are measured. On the periodic table, electron affinities tend to shift from negative to positive as we move from left to right.
Thus, when an electron is acquired by a neutral atom, the energy change is called as electron affinity.

Answer:
3, why because most of the time chemicals reacts within eachother to make new compound that's may lead the liquid chemicals to deflect some of the spectrom of light like red,yellow,blue
To solve such this we must know the concept of chemical reaction. There are so many ways to identify the chemical reaction. Therefore the correct options are option 3, 5.
What is chemical reaction?Chemical reaction is a process in which two or more than two molecules collide in right orientation and energy to form a new chemical compound. The mass of the overall reaction should be conserved that is mass can nether be created nor be destroyed in a chemical reaction.
There are so many types of chemical reaction reaction like combination reaction, double displacement reaction. The evidence of a chemical reaction are "the liquid turned pink when mixed" and "over time, a white solid formed at the bottom of the beaker".

Answer:
Looking at the table, Silver is definitely the most conductible metal there. It has the lowest electrical resistivity which means it allows for an easier flow of electrons, and it also has a higher thermal conductivity which means it would exhibit a higher conductivity. Diamond has the highest thermal conductivity, but the electrical resistivity is extremely high and due to its giant covalent/tetrahedral molecular structure (being an allotrope of Carbon), electrons can't necessarily jump around. Diamond wouldn't be a conductor at all.
The most simplest composition and structures provide a higher thermal conductivity. For example, with Diamond, we know that it is a structure made of covalent bonds of carbon, so its thermal conductivity is high.
Answer:
Q1
Copper
Explanation:
Copper is a good conductor of electricity, its resistance is high, and its chemical activity is weak
Q2
The thermal conductivity of a specific material is highly dependent on a number of factors. These include the temperature gradient, the properties of the material, and the path length that the heat follows.

Among the given images, the one which is an example of non-renewable source of energy is image -1 the cooking gas is a petroleum product and it is non-renewable.
What are non-renewable energy sources?Non-renewable energy sources are sources of energy that come from finite resources that cannot be replenished on a human timescale. They are called non-renewable because their reserves are being depleted faster than they can be replenished. These energy sources include:
Fossil fuels: Coal, oil, and natural gas are the three main types of fossil fuels. They are formed over millions of years from the remains of plants and animals that lived long ago. Fossil fuels are currently the most widely used sources of energy for electricity generation, transportation, and industrial processes.
Nuclear energy: Nuclear energy is produced through the process of nuclear fission, which involves splitting atoms of uranium or plutonium to release energy. Nuclear power plants generate electricity using this process.
Non-renewable energy sources are a major contributor to greenhouse gas emissions, which contribute to climate change. As a result, there is a growing need to transition to renewable energy sources that are sustainable and have a lower environmental impact.
