Answer:
hmm
Explanation:
The overall charge of an atom is zero. Atoms are made up of positively charged particles called protons and negatively charged particles called electrons as well as non-charged particles called neutrons.

An atom consists of a positively charged nucleus, surrounded by one or more negatively charged particles called electrons. The positive charges equal the negative charges, so the atom has no overall charge; it is electrically neutral.

The volume of the aqueous solution of sodium sulfate required is 153.85 mL.
<h3>Number of moles of the salt</h3>
The number of moles of the salt in the given mass is calculated as follows;
moles = reacting mass / molar mass
molar mass of sodium sulfate = 142 g/mole
moles = (4.27) / (142)
moles = 0.03 mole
<h3>Volume of the aqueous solution of sodium sulfate</h3>
Concentration = moles/volume in liters
0.195 = 0.03/V
V = 0.03/0.195
V = 0.15385 liters
V = 153.85 mL
Thus, the volume of the aqueous solution of sodium sulfate required is 153.85 mL.

Abuse of dopamine have been linked to the neurotransmitter dopamine.
Answer:
The order would be: X-Rays, Visible Light, and Infrared Waves.
X-Rays have the shortest wavelength out of all three, then Visible Light, and Infrared Waves have the longest wavelength of the three.
Explanation:
So basically, the LONGER the wavelength, the lower the energy. and the SHORTER the wavelength, the higher the energy. For example, Radio waves are the WEAKEST out of all the types of waves because they have the LONGEST wavelengths. Gamma Rays are the STRONGEST out of all the types of waves because they have the SHORTEST wavelengths. So Radio Waves have the lowest energy, and Gamma Rays have the highest energy.
Here is a list of all the types of waves in order from shortest wavelength to longest wavelengths:
Gamma Rays (Shortest Wavelengths, High Energy), then X-Rays would be the second strongest, then Ultraviolet waves, then Visible Light, then Infrared waves, then Microwaves, and lastly Radio Waves (Longest Wavelengths, Low Energy).
