What is matter?
Matter can be defined as anything that has mass and can occupy space.
Thus, any physical object or substance that is found on planet Earth is typically composed of matter.
The three (3) states of matter:
Since all matter are made up of atoms, they have a property of existing in three (3) distinct states and these include;

How many grams of solute are needed to order to prepare 100.00 mL of a 0.1000 M solution of a compound with a molecular weight of 350.0 g/mol
Answer:
i got 35 but i am as lost as you are so don't really take my answer as a trusted answer
The grams of solute are required.
The mass of solute is 3.5 g
c = Molarity = 0.1 M
M = Molar mass = 350 g/mol
V = Volume of solution = 100 mL = 0.1 L
n = Number of moles
m = Mass of solute
Molarity is given by
[tex]c=\dfrac{n}{V}\\\Rightarrow n=cV\\\Rightarrow n=0.1\times 0.1\\\Rightarrow n=0.01\ \text{moles}[/tex]
Molar mass is given by
[tex]M=\dfrac{m}{n}\\\Rightarrow m=Mn\\\Rightarrow m=350\times 0.01\\\Rightarrow m=3.5\ \text{g}[/tex]
The mass of solute is 3.5 g

(6) Predict the number of valence electrons for each of the following elements (4 pts)
(a) P
(b) Ar
(c) c
(d) Ni
Answer:
P = 5, Ar = 8, C = 4, Ni = 2
Explanation:
All these answers can be based off which column of the periodic table each element is in. This does exclude the transition medals in between the 2nd and 13th columns. Column 1 = 1, Column 2 = 2, Column 3 = 3 and so on. Transition metals can be determined based on their electron configuration, which in this case, Ni has 2 electrons in its outer most shell.

Imagine you are an astronaut and you travel to a planet with a much larger mass than Earth. How would this affect your weight? Explain your answer. (4 points)
Answer:
Explanation:
It may not make any difference. The information missing is the radius of the planet.
However for the purposes of the question, let us assume that it is roughly the same diameter of the earth. Then the weight of anyone would increase if the mass is all that changes..
The formula governing your weight is F = G * m1 *m2 / r^2. If m1 is the mass of the planet and it increases a lot then m2 (you) should increase. The question is done by a proportion.

Why did me need to have the same molecules in each bottle? and what would have happened if we didn't use the same molecules?
Background info: We learned about molecules and how when a object is heated the air becomes less dense and the molecules is the opposite since they don't spread out and become more dense. What I mean with this question is in class we experimented by putting a bubble on a bottle and putting it on a hot water, the water made the molecules inside less dense and the bubble went up but when we tried cold water the bubble went down.
Answer:
it's just like doing a test grade on children if you give them different tests they might not come up with the same results, the molecules need to be the same or else the experiment will be even.
Explanation:
whenever water is hot the molecules will bounce really fast in the bottle, whenever water is cold he will go really slow in the bottle
A student group is involved in a restoration study of a nearby disturbed area. They decide to collect six soil samples and analyze them for carbon (C) and nitrogen (N). Two of the samples are found to be very high in C and N, but the other four samples are low in both. The students also notice that the color of the two soil samples that are high in C and N is very dark.
Requried:
What is the most likely explanation of the data?
The very dark soils samples that contain the highest amounts of carbon and nitrogen is loamy soil.
Soil is the outermost portion of the earth's crust on which plants grow. The appearance of a soil sample gives an idea of the type and nature of the soil it is.
We are told that two out of the six soil samples gathered are very dark and contains an enormous amount of carbon and nitrogen. These two must be samples of loamy soil.

D
The green wavelength vibrates the air particles.
Answer:
When (B) the green wavelength is reflected, we are able to see green.
I hope this helped at all.
In an electromagnetic spectrum, complimentary colors are absorbed and reflected , the color which is visible is the reflected color, hence the green wavelength is reflected which enables to see the color green.
What is electromagnetic spectrum?The electromagnetic spectrum consists of electromagnetic radiation consists of waves made up of electromagnetic field which are capable of propogating through space and carry the radiant electromagnetic energy.
The radiation are composed of electromagnetic waves which are synchronized oscillations of electric and magnetic fields . They are created due to change which is periodic in electric as well as magnetic fields.

Calculate the mass of iron formed when 299g of iron (ii) oxide is reduced by excess carbon monoxide
Answer:
Mass = 88.12 g
Explanation:
Given data:
Mass of iron oxide = 126 g
Mass of iron formed = ?
Solution:
Chemical equation:
Fe₂O₃ + 3CO → 2Fe + 3CO₂
Number of moles of iron oxide:
Number of moles = mass/molar mass
Number of moles = 126 g/ 159.69 g/mol
Number of moles = 0.789 mol
Now we will compare the moles of iron with iron oxide.
Fe₂O₃ : Fe
1 : 2
0.789 : 2/1×0.789 = 1.578 mol
Mass of iron:
Mass = number of moles ×molar mass
Mass = 1.578 mol × 55.84 g/mol
Mass = 88.12 g

Matter in chemistry, is defined as any kind of substance that has mass and occupies space that means it has volume .Matter is composed up of atoms which may or not be of same type.
Atoms are further made up of sub atomic particles which are the protons ,neutrons and the electrons .The matter can exist in various states such as solids, liquids and gases depending on the conditions of temperature and pressure.
The states of matter are inter convertible into each other by changing the parameters of temperature and pressure.According to law of conservation of matter , matter can neither be created nor destroyed only its state changes .

How many protons,neutrons and electrons make a hydrogen atom
Explanation:
A hydrogen atom has an atomic number of 1.
So it's proton number will always be 1.
A neutral hydrogen atom does not have any charge.
So it has the same amount of electrons as protons, which turns out to be also 1.
A neutral hydrogen atom has an atomic mass of ≈1.00794amu≈1amu.
To find the amount of neutrons, we take the proton number and subtract it from the mass number.
1−1=0
So a neutral hydrogen atom has no neutrons.
In summary,
A hydrogen atom has
1 proton
1 electron
0 neutrons
another way of explaining:
The number of protons is the atomic number, and the number of protons plus neutrons is the atomic mass. For hydrogen, the atomic mass is 1 because there is one proton and no neutrons. For helium, it is 4: two protons and two neutrons
