Answer:

Both are made of two or more atoms.

Explanation:

A compound is two elements that are mixed together, no matter the amount element that it´s in the compound, it can be from 2 atoms to thousands of tons, those are still compounds, and molecules are 2 atoms of the same element that are together, so both are made 2 or more atoms, in the case of the molecule its two atoms of the same element, and in the case of the compound is two atoms of different elements.

Plzzzzz help me to solve this question.​
aleksklad [387]

Answer:

Explanation:

A1. Chemical indicator, any substance that gives a visible sign, usually by a colour change, of the presence or absence of a threshold concentration of a chemical species, such as an acid or an alkali in a solution. An example is the substance called methyl yellow, which imparts a yellow colour to an alkaline solution.

A2. The reaction of an acid with a base is called a neutralization reaction. The products of this reaction are a salt and water. ... For example, the reaction of hydrochloric acid, HCl, with sodium hydroxide, NaOH, solutions produces a solution of sodium chloride, NaCl, and some additional water molecules

A3. Methyl orange has the property to color alkaline and neutral water yellow. If the water becomes acidic, it turns red immediately.

Use the normal boiling points: propane, C3H8, –42.1˚C; butane, C4H10, –0.5˚C; pentane, C5H12, 36.1˚C; hexane, C6H14, 68.7˚C; hep

Answer:

The answer to your question is 126.1°C

Explanation:

                  Boiling point         Difference of boiling points  

C₃H₈             - 42.1°C

C₄H₁₀             -   0.5°C                 41.6 °C

C₅H₁₂               36.1°C                  36.6°C                       41.6 - 36.6 = 5°C          

C₆H₁₄               68.7°C                 32.6°C                        36.6 - 32.6 =4°C

C₇H₁₆               98.4°C                 29.7°C                        32.6 - 29.7 = 2.9°C

We can observe on the table that the difference of boiling points diminishes 1°C when the hydrocarbon has one more carbon, then the difference of temperature between the hydrocarbon of 8 carbons and the hydrocarbon of 7 carbons must be 2°C.

So, this difference is 29.7°C - 2°C = 27.7°C.

And the boiling point of octane is approximately 98.4 + 27.7°C = 126.1°C

What would happen if you shone a lazer light into a glass of water?
Aleonysh [2.5K]

Answer:

Reflection/change of direction

Explanation:

When the light of the laser hits the glass of water, it reflects and goes another direction. It's basically just a change of direction. The light is mostly in the glass of water and just some reflecting off of it.
