Answer:
The molecules move slower than the temp of 50°c and their average kinetic energy decreases.
Explanation:
kinetic energy cannot increase as temperature is reduced. molecules will still move with reduced motion.
The right answer is D. three electrons are gained, creating N-3
Nitrogen has 5 electrons in it's valence shell and octet rule states that the valence shell must have 8 electrons. To satisfy that, Nitrogen gains 3 electrons that are negatively charged.Therefore, it gets a negative charge.
So we know that the equation for density is:
where D is the density, m is the mass in grams, and V is the volume in mL.
So since we know two of the variables, mass and density, we can solve for the volume:
Therefore, the volume of this urine sample is 144.12mL.
I would love to help but it is 3 or is it 3 million?
