The answer is D. What makes a neutral atom neutral is that it has an even number of protons and neutrons. If the number of protons and neutrons are unbalanced, it is now an ion.

Answer:

D

Explanation:

An ion is created because an atom doesn't have a balanced number of protons and electrons. A positive ion is created by an atom losing an electron and a negative ion is created by an atom gaining an electron.

What are the total electron pairs in AsH3
tatiyna

AsH3 has five valence electrons, so the molecule will have 3 bonding domains and one non-bonding domain (lone pair) around the central atom. The geometry is trigonal pyramidal, and the angles are around 107 degrees. 

AsH3 and hydrogen are very close in electrongativity, so there really is no partial charges. There may be a slight electron pull towards hydrogen, but it would be nearly insignificant

Sometimes when performing a crystallization, one solvent alone will not work and you have to use a solvent-pair. Will the solven
love history [14]

For the crystallization purpose the combination of solvent process is known to be an effective process. But the solvent pair one have to choose crucially. The solvent which is completely in soluble into the other solvent can not work as a good solvent pair for the crystallization. The crystallization of any compound by the solvent pair process is depend upon the slow diffusion of a less polar solvent to the polar solvent or vice-versa.

If a compound is soluble in a polar solvent the slow diffusion of relatively low polar solvent will make crystal of the compound. But anyhow the solvents which are completely not immiscible to each other will not work for the purpose. Thus diethyl ether and water solvent pair can not be used for the crystallization process.

Identify the type of energy involved in each step:
77julia77 [94]

Answer:

a. Electric Energy

b. Light Energy

c. Thermal Energy

Explanation:

a. When a lamp is turned on by means of a switch, electric energy is usually used, since that is the form of energy that is generated when there is a potential difference between two points, which allows to establish an electric current, that electric current travels through the wires up to the bulb of the lamp

b. In this case a case of light energy is presented since that is the energy transported by the light and that is manifested on the matter in different ways, one of them is to remove the electrons from the metals. This is what usually happens in some types of light bulbs, that when the displacement of the electrons is promoted, a beam of light is generated.

c. The last case is a case of thermal energy, since this energy is that expressed as the total kinetic energy resulting from the random movements of atoms and molecules. This was what could happen in case b, when the beam of light was generated. This energy is released in the form of heat, and may present high temperatures.
