Which Of The Following Have The Correct Pairing Of Ion Charge To The Number Of Protons And Electrons

Answers

Answer 1

Answer:

Explanation:

O-2 means that there are 2 more electrons than protons. This one is incorrect.

Na + 1 is correct. 11 protons and 10 electrons.

N-3   is correct 7 protons and 10 electrons.

AL+3 is incorrect. It goes the other way 13 protons 10 electrons.

What is meant by the term isotopes?

Answers

It is each of two or more forms of the same element that contain equal numbers of protons but different numbers of neutrons in their nuclei, and hence differ in relative atomic mass but not in chemical properties; in particular, a radioactive form of an element.

What is energy? Write a paragraph describing the following forms of energy: mechanical energy, chemical energy, Sound energy and radiant energy. Include examples of each in your paragraph.

                                         Answer and Explanation

According to Science J Rank,

__________________________________________________________

Heat Energy

Heat energy is the movement of energy from one object to another. It is also called thermal energy. It can move in three ways: through conduction, convection, or radiation.

__________________________________________________________

Conduction occurs when heat moves directly from one object to another. What happens when you leave your car parked in a sunny parking lot on a hot day? The heat of the sun passes directly through the metal of the car and heats the air (and seats) on the inside.

__________________________________________________________

Energy Hot vehicles in the summer are a form of heat energy.

Convection is the movement of hot liquids or gases. For example, when you boil water, the liquid nearest the flame heats up first. As it gets hot, it rises, and the cooler water goes to the bottom where it gets heated. This continues until the water is boiled.

__________________________________________________________

Radiant Energy

Radiant energy is the energy created through electromagnetic waves, such as light, heat, or radio waves. The sun is our major source of radiant energy because it gives off a great amount of heat and light. Scientists use the electromagnetic spectrum to discuss the types of radiant energy. The electromagnetic spectrum lists all the types of radiant energy by the length of their waves. The shorter the wave, the more energy and heat are created.

__________________________________________________________

Electrical Energy

A huge maze of wires in every house carries electrical energy to do many different jobs, from lighting your home to cooking food.

Electricity starts at the atomic level. Atoms are made up of a nucleus, protons, and electrons. We create electricity by forcing electrons to move from atom to atom. Electrical energy is the movement of electrons through a conductor. A conductor is a material that can carry electricity, like the wiring in homes.

__________________________________________________________

Generators create the electricity used in our everyday lives, but other forms of electric energy occur naturally.

Lightning occurs when electrons are discharged from a cloud. Lightning is so powerful that if we could capture the electricity in a single bolt, it could power our entire home for days.

__________________________________________________________

Static Electricity occurs when an object (or person) gets charged with electrons. You may have experienced this when scuffing your feet on a carpet and then touching a doorknob. The electrons you built up jump from your hand to the metal of the doorknob, causing a powerful shock!

__________________________________________________________

Chemical Energy

Chemicals contain stored, or potential, energy to hold their atoms together. When chemicals are mixed together, a reaction can occur. Chemical energy is the energy released through a chemical reaction.

We can use the heat that these reactions give off. We can use it to cook, to heat our homes, and to burn the gasoline that moves our cars.

One of the major uses of chemical energy is to help produce electrical energy. Coal, gas, and other fuels are burned to run electric generators.

The chemical energy in batteries is changed into the electrical energy we need to run everything from flashlights to toys.

__________________________________________________________

Nuclear Energy

Atoms are so small that until recently even the most powerful microscopes could not see them. Yet when we split the nucleus of an atom, a tremendous amount of energy is released. Nuclear energy is the potential energy stored in the nucleus of an atom.

In a nuclear power plant, a reactor is used to split uranium atoms. This heat is used to turn water to steam. The steam powers a generator that creates electricity.

Nuclear power plants create about 20 percent of the electricity in the United States. Coal, oil, and natural gas help produce the rest.

3. What is found around the roots of some plants that turns nitrogen from the form we cannot use to the form we can use?

Answers

Answer:

Bacteria

Explanation:

Some plants, specifically leguminous plants form a symbiotic relationship with certain bacteria species called NITROGEN-FIXING BACTERIA in their root nodules. In this relationship, the bacteria species e.g nitrosomonas, nitrobacter etc help the plants fix atmospheric nitrogen (N2) or ammonium compounds, which are forms of nitrogen that are unusable to the plant into nitrates, a usable form.

Therefore, BACTERIA are the organisms found around the roots of these set of plants (legumes) that turns nitrogen from the form we cannot use to the form we can use.

What is ecosystem?

Ecosystem is defined as a system which consists of all living organisms and the physical components with which the living beings interact. The abiotic and biotic components are linked to each other through nutrient cycles and flow of energy.

Energy enters the system through the process of photosynthesis .Animals play an important role in transfer of energy as they feed on each other.As a result of this transfer of matter and energy takes place through the system .Living organisms also influence the quantity of biomass present.By decomposition of dead plants and animals by microbes nutrients are released back in to the soil.

Sodium is a soft, white metal that reacts violently with water. Chlorine is a poisonous yellow-green gas. During the chemical reaction between sodium and chlorine, table salt is produced. Which of the following statements correctly compares and contrasts the reactants with the resulting products used in a chemical equation?

A. The reactants are dangerous and the product can be eaten
B. The reactants and the products observe the law of conservation of mass
C. The reactants are a solid and a gas and the product is a gas
D. The reactants and the products are the same color

Answers

Answer:

B. The reactants and the products observe the law of conservation of mass

Explanation:

The reaction equation is given as:

            2Na  +  Cl₂  →   2NaCl

Such a chemical reactions usually obeys the law of conservation of mass. The law states that "in a chemical reaction, matter is neither created nor destroyed but bonds are rearranged".

So, the most correct thing is that reactants and products observe the law of conservation of mass. The number of atoms on both sides of the expression will be the same. Therefore, option B is correct.  

In science, all ideas are not tested with evidence from the natural world.

What is the difference between the atomic weight and the relative
atomic mass (RAM)?​

Answers

Answer:

Relative and average atomic mass both describe properties of an element related to its different isotopes. However, relative atomic mass is a standardized number that's assumed to be correct under most circumstances, while average atomic mass is only true for a specific sample.

Explanation:

Atomic weight is approximately equal to the number of protons and neutrons, with a little extra added by the electrons. The stability of the nucleus, and hence the atom's radioactivity, is heavily dependent upon the number of neutrons it contains.

Atomic mass is the mass of an atom of a chemical element expressed in atomic mass units. It is approximately equivalent to the number of protons and neutrons in the atom (the mass number) or to the average number.
