D. is the same in each compound that an element forms
Hope it helps:)
NO3- will affect the pH of a solution. The ion will decrease the pH of a neutral solution. No3- ion is a conjugate base of a strong acid, therefore, if it added to a neutral solution of pH 7, it will change the pH of the solution by decreasing the pH, that is, the solution will become acidic in nature.
Answer:
(d) the ion with 24 electrons, 30 neutrons, and a 3+ charge ... (b) the ion with 36 electrons, 35 protons, and 45 neutrons.
Particles in solids are always vibrating (moving back and forth) in place. The vibrational motion of particles in solids is kinetic energy. Heat makes the particles in a solid vibrate faster, giving them more kinetic energy. ... When a sample of solid, liquid, or gas matter heats up, it expands.
