Answer:
The H+ atoms will become neutralized by the OH- ions in the water. This is due to the fact that when acids are dissovled in water, they give H+ ions (Hydrogen ions). When the H+ ions from the acid join with the OH- ions in the base (water), they'll become neutralized and form H₂O (Water molecule).
UV rays and X-rays are electromagnetic waves (do not require material medium for transmission). They are part of the electromagnetic spectrum and travel with the speed of light (3×10^8 m/s). In this case i believe the answer is C, X-rays have a higher frequency compared to UV rays.
To find the number of neutrons in an atom you can use and equation
N = Mass no. - Protons
N of chlorine-36 = 36 - 17 = 19
so chlorine-36 has 19 neutrons
hope that helps
