H2O
Answers
Answer:
Na(Sodium) and C(Carbon) only
Answer:
Na, C
Explanation:
1. KCl, or potassium chloride, is a combination of two elements- so it's a chemical compound.
2. Na, or sodium, can be found on the periodic table of elements. Therefore, it is an element.
3. C, or carbon, can also be found on the periodic table of elements. Therefore, it is an element.
4. H20, or water, is a combination of 2 hydrogen atoms that bonded into an oxygen atom. Combination of 2 or more elements is a chemical compound.
Therefore, the answers are Na and C.

Helium is less dense. Because helium is lighter than air, a helium balloon rises, just as an air bubble rises in more dense water
Explanation:
Also why not. It just is.

This is due to the fact that helium has a lower density. A helium balloon rises like an air bubble in more dense water because helium is lighter than air. Another gas lighter than air is hydrogen, which is even lighter than helium.

Which ion has the correct charge?
07-
Na 2+
N 3+
Ca2+
Answers
Answer:
Ca(2+)
Explanation:
Sodium (Na) only have one valence electron and will lose it in order to gain a full octet. There will be an unbalance of electrons and protons where there are more protons there electrons. The correct ion formula for sodium is Na (1+).
Nitrogen has 5 valence electrons and will gain three more to gain a full octet. There will be an unbalance where there are more electrons then protons. Nitrogen will form the ion N (3-).
Calcium has two valence electrons and will lose them in order to gain a full octet. There will be an unbalance where there are more protons then electrons. Calcium will form the ion Ca 2+
Therefore, Ca2+ is the ion with the correct charge.

The first stage of the experiment is focusing only on the physical properties of acidic property.
What is physical property?A physical property would be any quantifiable attribute whose value describes the condition of a physical system. Changes in a system's physical attributes are able to characterize its transitions between brief states. Physical attributes are sometimes known as observables.
Physical characteristics are frequently classified as intense or extensive. An intense property is independent of the system's size or extent, as well as the amount of material in the item, whereas an extended property has an additive link. The first stage of the experiment is focusing only on the physical properties of acidic property.
Therefore, the first stage of the experiment is focusing only on the physical properties of acidic property.

Put the substance in a 25 mL beaker.
Now, observe and record the following:
state of matter:
appearance and texture:
crystalline structure:
Answers
Answer:
liquid no not a solid
Explanation:
When you put the substance in a 25 mL beaker. then the state of matter is solid, appearance and texture are powdered and crystalline structure is not solid(powder).
What are crystalline structures and states of matter?The term "crystalline structure" refers to the arrangement of atoms, ions, or molecules in a crystalline solid. A crystalline solid is a type of material where the constituent particles are arranged in a regular, repeating pattern. This regular arrangement results in a characteristic geometric shape for the crystals. Examples of crystalline solids include salt, sugar, and diamond.
On the other hand, the term "state of matter" refers to the physical form in which matter exists. There are three primary states of matter: solid, liquid, and gas.
Solids have a definite shape and volume and their constituent particles are held tightly together by strong intermolecular forces.
Liquids have a definite volume but no definite shape, and their constituent particles are held together by weaker intermolecular forces.
Gases have no definite shape or volume, and their constituent particles are far apart and move freely.
Other states of matter, such as plasma and Bose-Einstein condensate, also exist but they are less common in everyday life.
Therefore, the state of matter: is solid, its appearance and texture: are powdered, and the crystalline structure: is not solid.

In Experiment 1, what volume did the propane gas occupy in the Erlenmeyer flask before the addition of any water?
Answers
This question is mentioning an experiment that is not being described about the volume of the propane gas in an Erlenmeyer before the addition of water.
In this case, since no information is given, it is possible to propose a suggested procedure of how to figure it out via gas laws, specifically, the ideal gas one, since no change is decribed before the addition of water:
[tex]PV=nRT[/tex]
Thus, you can solve for the volume, by dividing both sides by the pressure, so that you will get:
[tex]V=\frac{nRT}{P}[/tex]
Now, to ensure a correct calculation, make sure you have the moles (divide by the molar mass of propane, 44,1 g/mol, if you were given the grams), the temperature in K (add 273.15 if you have degree Celsius), the ideas gas constant as 0.08206 and the pressure in atm, in order to have consistent units.
If you need the volume in milliliters, you will need to multiply the previous answer by 1000 in order to perform the appropriate conversion.
