- Table salt is a substance - sodium chloride (NaCl); the salt contain two elements chemically bonded.
- Salt water is a mixture of water (H2O), the solvent, with sodium chloride and other salts; also contain insoluble materials.
- Sand is a powdered material; sand has different compositions: calcium carbonate, lava, silicates etc.
Sand may be a substance if it is pure.

What substance in the table is a liquid at 105 degrees?
To determine which substance in the table is a liquid at 105 degrees, you would need to know the melting and boiling points of the substances listed. A substance that has a melting point below 105 degrees and a boiling point above 105 degrees would remain in liquid form at that temperature. Please provide the specific substances for a more accurate answer.
What is the simplest type of substance you know of?
The simplest type of substance is an element. They cannot be split up even by chemical reactions. There are over 100 elements, and the Periodic Table is a list of them.
How could you use the physical properties of melting and boiling point to identify a substance?
If you know the melting point and boiling point of a substance, you could look them up in a table to see what substances have those melting and boiling points. In practice, there are lots of other tests you'd probably want to do in addition, because in general there's no guarantee that an unknown substance is a single pure compound.
How do you know which letters are in the periodic table?
You look at the periodic table.
True or false Every know naturally occurring element is found in at least trace amounts in seawater?
True. Every naturally occurring element on the periodic table has been found in at least trace amounts in seawater, largely due to geological and biological processes. While some elements may be present in very low concentrations, they can still be detected. This includes metals, nonmetals, and metalloids, reflecting the ocean's complex chemistry and interactions with the Earth's crust.
Can you explain the atomic mass of the element beryllium?
Berlium is a element in the periodic table i think. i dont know for certian what they use it for though
What is the average absolute salinity of seawater?
i really dont know

What will happen if red blood cells are transferred to seawater?
as u know, seawater is salty ,that is hypertonic.. when u place RBC in sea water it will swell and then burst.
Which ions comprise about 85 percent of the solutes in seawater?
I don't know about percentages, but since sea water has a lot of salt, I would expect that to be sodium and chlorine. (That is the common table salt; sea water also has some other salts.)
What is the simplest type of substance you know of?
The simplest type of substance is an element. They cannot be split up even by chemical reactions. There are over 100 elements, and the Periodic Table is a list of them.
How would you know when sea water is saturated?
There are certain testing methods that you can utilize when checking if seawater is saturated. Depending on what you want to test, there are specific testing kits for seawater for each chemical you are testing for.
What is the mass of a 600 ml sample of seawater with a density of gm?
To calculate the mass of a 600 ml sample of seawater, you need to know the density. If the density of seawater is approximately 1.025 g/ml, the mass can be calculated using the formula: mass = density × volume. Therefore, the mass of the seawater would be approximately 600 ml × 1.025 g/ml = 615 grams.
What you know about substance?
Quite a lot - depending on the specific substance you are talking about. What do you want to know?
What do I need to know before purchasing a used pool table?
It's good to know how you plan on using the table. The three major things to look for are the level of the table, the underlay of the table, and the challenge of the table.
You want to know about paragraphs in English?
Ask your teacher to explain paragraphs. You can also check the index and table of contents in your English book, find the section on paragraphs, and read it. If you don't know what an index and table of contents are, or don't know how to use them, ask your teacher to explain it to you. Teachers are there to help you learn. If you don't understand something, don't be afraid to ask for help.
