can someone go answer my qeastion please this is what it looks like

Answer:

See attached picture!

Explanation:

You are dealing with salts.  This means that you write the name of the metal (sodium) with the name of the nonmetal (chloride).  You need to change the end of the name of the nonmetal (chlorine to chloride; bromine to bromide).

To find the balanced compound, use the charges of the cations and anions.  You need to write the compounds so that the total charge of the salt is 0.

Answer:

It is a metal

Explanation:

Acceleration is the rate of change of velocity with time.

Acceleration= velocity/time

Answer:

youre not showing a drawing. look at the table. electronegativity trend is “down” and “right”. you should get your answer by looking at that trend. the more electronegative, the more reactive.

Answer:

Independent variable: SIZE OF NAILS

Dependent variable: NUMBER OF PAPER CLIPS

Explanation:

The independent variable in an experiment is the variable that is changed or manipulated by the experimenter in order to effect a measurable response. In this investigation, the DIFFERENT SIZES OF NAILS USED is the INDEPENDENT VARIABLE.

The dependent variable is the variable that is measured in the experiment. It is the variable that responds to changes made to the independent variable. In this investigation, THE NUMBER OF PAPER CLIPS the electromagnet could pick up is the DEPENDENT VARIABLE.

The dependent variable is the number of paper clips that the electromagnet could pick up while the independent variable is sizes of nail used.

An experiment consists of;

The independent variable is the variable that is being manipulated while the dependent variable changes with changes in the independent variable.

In this experiment, the dependent variable is the number of paper clips that the electromagnet could pick up while the independent variable is sizes of nail used.

C?

Explanation:

Answer:

C

Explanation:

Water which is a liquid becomes ice which is a solid

That would be C, due to the fact that the water changes from a liquid to a solid. (I hope that helped ^^)

Phosphodiester bonds found between the monomers on the different strands of DNA.

Deoxyribonucleic acid is called as DNA. The molecule found inside cells that carry the genetic material necessary for an organism to develop and function. This knowledge can be passed on from one generation to the next thanks to DNA molecules.

The information molecule is DNA. It contains information needed to create proteins, which are other big molecules.

In DNA polymers, phosphodiester bonds link the 5' carbon of one nucleotide and the 3' carbon of another nucleotide. In a DNA polymer, phosphodiester bonds strong electromagnetic attractants join the nucleotide monomers together.

Thus, Phosphodiester bonds found between the monomers on the different strands of DNA.

Explanation:

Answer:

B

Explanation:

i just take the test

An ionic bond has a high melting point because a lot of energy is required to overcome the attractive forces that hold the ionic crystal together. The correct option is B.

In an ionic bond, atoms transfer electrons to form positively charged cations and negatively charged anions. These oppositely charged ions are attracted to each other, creating strong electrostatic forces between them.

When a solid ionic compound is heated, the thermal energy increases, causing the ions to vibrate more vigorously. As the temperature continues to rise, the ions gain enough energy to break free from their fixed positions within the crystal lattice. This requires a lot of energy because the attractive forces between the ions are strong and must be overcome.

Thus, the correct option is B.

Answer:

4is the answer

Explanation:

They describe different forms of matter, solid and liquid. As well as both being entirely differently structured forms of matter.

They distinguish between solid and liquid matter. In addition to being completely different types of matter.

Matter is defined as everything that takes up space other words, the "material" that makes up the universe.

All matter is composed of substances known as elements, each of which has unique chemical and physical properties and cannot be decomposed into other materials through ordinary chemical reactions.

Atoms and molecules make up some of the material in the category of solids, liquids, and gases.

The matter that makes up wood have characteristics of any solid, i.e., high intermolecular force of attraction that holds it shape.

The matter that is making water will have liquid characteristics, which do not have a particular shape and will have weak intermolecular forces of attraction.

Thus, this is the chief difference between the "matter that makes up wood" and the "matter that makes up water".

C6H6

Explanation:

Now let us take a recap of Joelle's criteria for a wall filling material;

1) the material must be a thermal insulator

2) materials should not be acidic

3) they will not dissolve too easily in water.

If we consider the options provided, Na6Ba6  and NeNa do not exist. HCl is an acid and does not match Joelle's criteria. Hence the answer must be C6H6.

Explanation:

Each time you add a neutron, it adds one mass number to the mass because each neutron and proton weighs approximately 1 amu.

Answer:

The mass increases

Explanation:

When protons and neutrons are added, the mass increases. Electrons, on the other hand, are so small they do not affect the mass.

Answer:

(see below)

Explanation:

Using process of elimination:

A) lose energy

When a liquid freezes into a solid, the particles move a lot slower because the once-flowing particles are now about to be stuck in place, barely vibrating in its structure.

So, yes, they has lost energy, but there can be a better answer.

B) gain energy

When a liquid freezes into a solid, the particles move a lot slower, so there is no way there is more energy now. If there was to be more energy, it would be a gas now.

So, no, they did not gain energy.

C) move faster

When a liquid freezes into a solid, the particles move a lot slower, so there is no way they're moving faster now. Otherwise it would be a gas now.

So, no, they did not move faster.

D) disappear

Particles of a substance don't just . . . disappear. There is no way matter can be destroyed or created, only changed in form, according to the Conservation of Matter.

So, no, they did not disappear.

So the answer is most likely A.
