Depending on the numbers on the side for the price, it could be A or B; if the numbers go from higher to lower then its A, if it goes from lower to higher then its B
Answer:
True;
True;
False;
True;
True.
Explanation:
Organic compounds can be found pure, but generally, they are in mixtures, such as the petroleum, so it is possible to the compound received be impure;
Organic compounds can be found in the three states: solid, liquid or gas. The state will depend on the molecular forces in it and its molar mass. For example, gasoline is liquid in the ambient temperature, natural gas is a gas, and the glucose is solid;
The main characteristic of the organic compounds is the presence of C and H, the other elements can or can't be in the structure: O, N, halogens, and S;
Because of the carbon can form chains, there are several million possible known organic compounds;
The spectroscopic would give some results such as composition, molar mass, and diffraction, and with these results, it would be possible to identify some chemical properties and the tests needs more identification.
Shampoo tubes are hollow tubes so things can be stored or used as a conducter as it is metal.
Decreasing
Increasing
Explanation:
We can change gas to liquid by decreasing the temperature and increasing the pressure.
- Temperature is the degree of hotness or coldness of a body.
- It is a function of how much heat it has absorbed or lost.
- Heat causes the thermal energy of a system to increase and the particles becomes randomized.
- Pressure is the force per unit area of particles.
- If we decrease the temperature of gases, they have less kinetic energy and entropy reduces.
- The will not be random.
- Further increasing their pressure will bring them together and make them flow like liquid.
- This phase change is often called condensation.
