Answer;
-Copper (Cu)
Explanation;
-While all metals can conduct electricity, certain metals are more commonly used due to being highly conductive. The most common example is Copper. It is highly conductive which is why it is has been used in electrical wiring.
-Copper is used for electrical wiring because it is a good conductor of electricity. Metal particles are held together by strong metallic bonds, which is why they have high melting and boiling points. The free electrons in metals can move through the metal, allowing metals to conduct electricity.
Hello. Your question is missing data, which makes it difficult to answer it with exactness, but I will try to help you in the best possible way.
If the reaction absorbs energy it means that the reaction is endothermic. This is because endortemic reactions are those that absorb energy from the environment, as opposed to exothermic reactions that release energy into the environment.
In that case, if the reaction is absorbing energy, it is appropriate for the water bath temperature to drop.
Answer:
It is not considered as a vacuum because the space around is not empty the space around it is filled with air like example the space has no air.
There are 3 Barium, 2 Phosphorus and 8 Oxygen in Barium Phosphate (Ba3(PO4)2, making 13 units. Multiply 0.0350 mol given by 13 and then you get 0.455 mol. Since they want atoms, multiply 0.455 by Avogadro's number (0.455 x 6.023 x 1023) and you get 2.74 atoms of barium phosphate.
Answer: When sand is added to water it either hangs in the water or forms a layer at the bottom of the container. Sand therefore does not dissolve in water and is insoluble. It is easy to separate sand and water by filtering the mixture. Salt can be separated from a solution through evaporation.
