Answers
Answer:
1) takes the shape of its container ( liquid and gas).
2) fills all available space (gas)
3) maintains its shape ( solid)
4) can be poured ( liquid)
5) is compressible ( gas)
6) has a fixed volume ( liquid and solid)
Explanation:
Matter is simply defined as anything that has weight and occupies space. It exists in three states, namely: solid, liquid and gaseous states.
The properties of different states of matter includes:
SOLID STATE
--> It has a definite shape: The shape of a solid is fixed; it does not depend on the shape of other materials.
--> It has a definite volume: it occupies its own shape due to the force of cohesion among its molecules.
--> It is tightly packed: The molecular movements of particles are negligible.
LIQUID STATE
--> liquid has a defined volume.
--> it has no definite shape: There is no specific shape of a liquid. It occupies any available space. It's shape depends on the shape of the container into which it is poured.
GASEOUS STATE
--> it has no fixed shape: Due to the distance in the molecules of gas, the gaseous state has no shape. It occupies the shape of its container.
--> It has no fixed volume: it occupies the shape of any container that is closed.
--> It is highly compressible: The particles of gas are far off from one another and there is room for collision.

How can you change a objects state of matter
Answers
Answer:
Changing states of matter occur when matter loses or absorbs energy. When a substance absorbs energy the atoms and molecules move more rapidly and this increased kinetic energy pushes particles far enough, that they change form. This energy is usually heat or thermal energy.

g If you forgot to fill the tip of the NaOH buret, took your initial reading and then completed the titration, what measurement would be affected
Answers
Answer:
The volume of NaOH used
Explanation:
The tip of the buret is part of its calibration. If this tip is not filled before taking the initial reading, the volume of NaOH used at the end of the titration would be inaccurate.
In order to avoid this, the valve of the buret should be opened and the NaOH allowed to displace whatever air that might have been trapped at the tip before the initial buret reading is taken and the titration is carried out.

O Occurs in substances that have a repeating lattice structure
O Occurs in substances that have discrete molecular structure
O Occurs in substances that have high melting points
Answers
Answer: it ISNT occurs in substances that have discrete molecular structure
Explanation:
I took the test
The characteristics that can be written only in space B is they occur in substances that have at least one non-metal. The correct option is A.
What is ionic and covalent bond?Ionic bonds are formed when two electrically charged elements shred their charged ions. Covalent bonds are formed when there is a mutual sharing of electrons between the atoms.
One condition that is similar in both is both bonds needed one non-metal to form the bond.
Thus, the correct option is A, which occurs in substances that have at least one non-metal.

If you add 50 mL of 0.20 M NaOH to a 50 mL solution of 0.60 M HF, what is the pH of the resulting buffer
Answers
Answer:
pH = 2.87
Explanation:
When NaOH reacts with HF NaF and H2O are produced:
NaOH + HF → NaF + H2O
That means after the reaction moles of NaF are equal to moles of NaOH added and moles of HF are initial moles of HF - moles of NaOH added:
Moles NaOH = Moles NaF:
0.050L * (0.20mol/L) = 0.01 moles of NaF
Moles HF:
0.050L * (0.60mol/L) = 0.03 moles HF = Initial moles
0.03 moles - 0.01 moles = 0.02 moles HF
To find pH we need to use H-H equation to determine pH of the buffer:
pH = pKa + log [NaF] / [HF]
Where pH is pH of the buffer
pKa is pKa of HF-NaF buffer: 3.17
And [] could be taken as moles of each species.
That is:
pH = 3.17 + log [0.01] / [0.02]
pH = 2.87

are atoms considered the building blocks of life?
Answers
Answer:
Explanation:
Atoms are the basic building blocks of ordinary matter. Atoms can join together to form molecules, which in turn form most of the objects around you. ... A particular atom will have the same number of protons and electrons and most atoms have at least as many neutrons as protons.
They are the building blocks of everything and what makes elements it’s like the core and they do bond together to make different elements so yeah
