Answer:
Candle wax will melt to a liquid and burn as a gas. Only covalent compounds can be liquid or gas!
Explanation:
Question: Is Wax Ionic Or Covalent? - Ceramicsexpandusceramics.com
In the given question, wax is a covalent compound because it is composed of nonmetal atoms that share electrons to create covalent bonds.
Covalent compounds are formed when two or more nonmetal atoms share electrons in order to achieve a stable electron configuration.
Wax is made up of long-chain hydrocarbons, which are molecules that contain only carbon and hydrogen atoms. The carbon and hydrogen atoms in these molecules share electrons to form covalent bonds.Ionic compounds, on the other hand, are formed when a metal and a nonmetal react.Therefore, wax is a covalent compound because it is made up of non-metal atoms sharing electrons to form covalent bonds.

How can you tell if an element is a metal or a nonmetal??
Answer:
Elements to the left of the line are considered metals. Elements just to the right of the line exhibit properties of both metals and nonmetals and are termed metalloids or semimetals. Elements to the far right of the periodic table are nonmetals. The exception is hydrogen (H), the first element on the periodic table.
Explanation:
Answer:
looking at its metallic luster
Explanation:
Elements may be classified as either metals or nonmetals based on their properties. Much of the time, you can tell an element is a metal simply by looking at its metallic luster, but this isn't the only distinction between these two general groups of elements. Most elements are metals.

Which of the following occurs when a liquid becomes a gas
Answer:
Boiling occurs when a liquid changes to a gas below its surface as well as at the surface. The temperature at which a liquid boils is called its boiling point. The opposite of vaporization is called condensation. Sublimation occurs when the surface particles of a solid gain enough energy that they form a gas.Boiling occurs when a liquid changes to a gas below its surface as well as at the surface.

when water changes state from a liquid to a solid is energy absorbed or lost?
Answer:
Loses
Explanation:
liquid changes into solid, heat is released. The energy released upon freezing, known as the enthalpy of fusion, is a latent heat, and is exactly the same as the energy required to melt the same amount of the solid.
Answer:
Matter either loses or absorbs energy when it changes from one state to another. For example, when matter changes from a liquid to a solid, it loses energy. The opposite happens when matter changes from a solid to a liquid. For a solid to change to a liquid, matter must absorb energy from its surroundings.

A monatomic ion always have one unit of charge. (+1 or -1) on the species
true or false
Answer:
No, this is invalid. The term mono in front of monoatomic simply refers to the number of atoms that are present in a compound or simply by itself it has no relationship with respect to the overall charge of the compound.
Explanation:
For instance Ca is considered as a monoatomic ion but it has a charge of +2.

Which of the subatomic particles are most responsible for the identity of an element?
neutrons
electrons
atoms
protons
Protons
Protons are the subatomic particle that determines the identity of an element.
Answer:
Explanation:Protons and neutrons are located in the nucleus of an atom and determine the mass of an atom. Protons have a positive electrical charge and electrons have a negative electrical charge. Atoms that have the same number of protons and electrons do not have an electrical charge.
What is the freezing point on this graph?
Answer:
Point a becuse it is the closest to -5*
Explanation:
Answer:
-5
Explanation:
Negative numbers get you confused.
- = Negative
5 = Number
You know 5 right?
I I I I I - 5
5 is a really less number already.
If you add a negative it will be double small.
Now lets figure out the problem:
What is the freezing point on this graph?
-5 is the smallest number
5 is bigger than -5
15 is bigger than 5 and -5
25 is bigger than all the numbers.
I know what your thinking. 25 is totally not the answer. Its the biggest number. Freezing is a very low number. What number is the lowest out of -5, 5, 15, 25. You see -5.
Therefore, -5 is freezing.

What is States of matter ?
When energy is added or removed to matter in the form of heat, it changes state to form a state of matter.
A state of matter is defined as one of the ways in which matter can interact with itself to form a homogeneous phase.
Therefore , During a change in state, energy is transferred in the form
of heat. Hence, Option (A) is correct.

Explain the law of conservation of mass.
Answer:
The law of conservation of mass or principle of mass conservation states that for any system closed to all transfers of matter and energy, the mass of the system must remain constant over time, as the system's mass cannot change, so quantity can neither be added nor be removed.

Electrons are typically represented by - or E
Gases ___ out and fill their container completely
Answer: Gases have the lowest density of the three, are highly compressible, and completely fill any container in which they are placed. Gases behave this way because their intermolecular forces are relatively weak, so their molecules are constantly moving independently of the other molecules present. Solids, in contrast, are relatively dense, rigid, and incompressible because their intermolecular forces are so strong that the molecules are essentially locked in place.

=================
Selection:
These are in approximate order:
Hypothesize: Build an explanation of the observation. The hypothesis should be done after a thorough review of existing information. Library database searches and researcher interviews are suggested.Predict: prediction of what would happen if the explanation were correct. E.g., If an atom is homogenous and has no internal structure, then bombarding it with with neutrons will result in most neutrons going right through the atom, and none would be reflected backwards.Plan and conduct investigations: Design experiments that test the hypothesis. E.g., see if any neutrons are reflected backwards. If they are, the hypothesis needs to be changed.
Measure: Do the work. Calibrate the equipment and record everything.
Record and display data: Publish the results and conclusions for peer review. Seek other's input in order to generate general agreement that the data, procedure, and conclusions are warranted.
===
Use numbers? Nah. Not if they are not required to reach a conclusion.(e.g., the precipitate will be pink or the reaction will stink).
Use Time and Space Relationships: Yes, but only if the hypothesis depends on them.
Classify and Order: OK, especially if you are a biologist, but not always necessary.
Use variable: usually, but what and how depends on the experiment.
Blame: Place blame on the lab partner (Just kidding).
