OR

Hello mr/mrs (name) I could understand what we were doing in class I would like it if you could break it down more or explain better to me

OR just say something it had something to do with your internet such as

Hello mr/mrs (name) I didn't understand what you were saying during our class due to some of my internet issues I was have throughout the day. I hope you can explain what we did during the class.

Those may be some of my excuses I've used before

they have worked for me:)

I don't know if that helped?:/

Answer:A

Explanation:the water will start to boil representing the yellow particles.

Answer:

A

Explanation:

Lol I'm doing the test right now and I have notes

Answer:

the one with the lower ionization energy is more likely to be positive as it is easier to remove the valence electron that causes the positive charge

element a is likely in the s block as that is a low ionization energy and they get larger as you move up and to the R in the table

and element b is likely in the p block for the same reason

Explanation:

Answer:

I think it would be D. None of the above

Explanation:

why I think this is because none of the answers really adds up to it

Answer:

false

Explanation:

It is a physical reaction because it is being heated.

Answer:

False

Explanation:

Just because the iron was melted into wires does not mean that it isn't iron. It is still iron just in a different form.

Answer:

The number of electrons in a neutral atom is equal to the number of protons. The mass number of the atom (M) is equal to the sum of the number of protons and neutrons in the nucleus.

sorry if im wrong

Explanation:

Answer:

Absorbed will be harder to spot than releasing because take this as it's like a tire. A tire will go smaller when it has no air compared to when it has air. But absorbed it the opposite. It gets bigger with more air and etc.

Explanation:

My answer don't copy and paste change it a little.

Answer:

Individual solute particles are broken apart from the solid by the;

c. Solvent

Explanation:

A solution is the homogeneous mixture that is made up of two or more substances formed by dissolving a substance which can be a solid, liquid or gas in another substance known as the solvent which normally the larger part of the fraction of the solution than the solute and can also be a solid, liquid or a gas

In a solution the solvent particles serves to brake of and disperser parts of a solid solute to form a more or less homogeneous mixture

Therefore, the solute particles are broken by the solvent particles in a solution

Answer:

119,059.5 g/mol

Explanation:

First, find the mass of N2

On the periodic table, nitrogen is 14.007

Because there are two nitrogens, multiply it by 2

14.007*2 = 28.014 g

Now convert... (also don't let that exponent intimidate you! You can change it to 4250 if that makes it easier)

4.25 × 10³ mol * 28.014 g/1 mol = 119059.5 g/mol

The term “INTERmolecular forces” is used to describe the forces of attraction between atoms, molecules, and ions when they are placed close to each other.

In liquids, particles are quite close together and move with random motion throughout the container. Particles move rapidly in all directions but collide with each other more frequently than in gases due to shorter distances between particles.

In a liquid, intermolecular attractive forces hold the molecules in contact, although they still have sufficient KE to move past each other. Intermolecular attractive forces, collectively referred to as van der Waals forces, are responsible for the behaviour of liquids and solids and are electrostatic in nature.

The chemical formula of CO, Fe₂O₃, and C₂H₄ contain atoms of two different elements. Therefore, option (D) is correct.

A chemical formula provides information about the chemical proportions of atoms of each element that are present in a molecule or chemical compound. The chemical formula can be represented by using chemical symbols of elements, numbers (subscripts), and other symbols, such as commas, dashes, brackets, and plus (+) and minus (−) signs.

A chemical formula of a compound has no words but can be written in certain simple chemical structures. Chemical formulae can be more limited in power than chemical names and structural formulae. There are two kinds of chemical formulas in which one empirical formula and another molecular formula.

In the chemical formula of carbon monoxide (CO) has carbon and oxygen two different elements. In the chemical formula of iron oxide (Fe₂O₃)  iron and oxygen are two different elements. In the chemical formula of ethane (C₂H₄ ) has carbon and hydrogen two different elements.

Answer:

Explanation:

Balanced forces  are opposite in direction and equal in size.

Balanced forces are  in a state of equilibrium.

Answer:

Balanced forces are forces whose net amount remains zero.

This can take place when two equal forces are acting in opposite direction.

Balanced forces don't make any  change in the position of objects

Answer:

10A because they are series

Answer:

[tex]a=123.04\ m/s^2[/tex]

Explanation:

Given that,

Force applied to a soccer player, F = 56.6 N

The mass of the ball, m = 0.46 kg

We need to find the acceleration of the soccer ball. The force acting on the ball is given by :

F = ma

Where

a is the acceleration

[tex]a=\dfrac{F}{m}\\\\a=\dfrac{56.6 }{0.46 }\\\\a=123.04\ m/s^2[/tex]

So, the required solution is [tex]123.04\ m/s^2[/tex].

Answer:

Yes

Explanation:

Why is glycerol more viscous than water?

The glycerine is more viscous than water because due to presence of hydrogen atoms , we all know that glycerine has more hydrogen bonding than water molecule , which makes an aggregation which means that glycerine is more viscous than water , in simple words glycerine can't flow as that of water molecule.

Answer:

D: 0.6 moles

Explanation:

First we balance the equation:

There are two NO₃ species on the right side, so we put a two before  AgNO₃:

Now we put a two before Ag on the right, to balance the Ag atoms:

The equation is now balanced.

Now we convert 3.6x10²³ atoms of zinc to moles, using Avogadro's number:

Then we convert 0.6 moles of zinc into moles of silver, using the stoichiometric coefficients of the balanced equation:

Thus the answer is option D.
