<span>The answer is A. Copper and silver are two examples of atoms that will form a metallic bond. Pure metals in solid state form nets similar to crystals, but they are not ionic. The electrons of the valence shell are shared by all the atoms. The electrons can move freely in what is called a "sea of electrons" which is what confere metals the property of conducting electricity.</span>
The IUPAC name of the compound shown in the image is 4-bromo butyne.
<h3>What is IUPAC?</h3>
IUPAC is a body in chemistry that stands for International Union of Pure and Applied Chemistry.
IUPAC functions in the naming of organic compounds in chemistry.
According to the image in this question, the functional group of the compound is a triple carbon bond meaning that it is an alkyne.
Bromine is attached to the fourth carbon, hence, the IUPAC name of the compound is 4-bromo butyne.

Answer:
1. <u>No, you cannot calculate the solubility of X in water at 26ºC.</u>
Explanation:
You cannot calculate the solubility of X in <em>water at 26 degrees Celsius </em>because you do not know whether the solution formed by dissolving the crystals in 3.00 liters of water is saturaed or not.
The only way to determine the solubility of the compound X is by dissolving the crystals in certain (measured) amount of water and making sure that some crystals remain undissolved, as a solid on the bottom of the beaker.
Next, you should filter the solution to remove the undissolved crystals. Then, weigh the solution, evaporate, wash, dry, and weigh the crystals.
Then you have the mass of the crystals dissolved and the mass of the solution which will let you calculate the mass of pure water, and then the solubility.
Answer:
c. a small amount
Explanation:
Trace elements (or trace metals) are minerals present in living tissues in small amounts.
Answer:
As a wavelength increases in size, its frequency and energy (E) decrease. From these equations you may realize that as the frequency increases, the wavelength gets shorter. As the frequency decreases, the wavelength gets longer.
