The 1st one. Fertilizers are like food for plants, and that's what an algae is, sorta. Trout's don't eat algae and if there's too much algae around, it gets dirty and they eventually die because of the amount of bacteria in the algae. It's the same thing if you have a fish tank.

Which of the following leads to a higher rate of diffusion?
miv72 [106K]
<h3><u>Answer;</u></h3>

Higher velocity of particles

<h3><u>Explanation;</u></h3>

The diffusion rate is determined by a variety of factors which includes;

  • Temperature such that the higher the temperature, the more kinetic energy the particles will have, so they will move and mix more quickly and the diffusion rate will be high.
  • Concentration gradient such that the greater the difference in concentration, the quicker the rate of diffusion.
  • Higher velocity of particles increases the diffusion rate as this means more kinetic energy by the particles and hence the particles will mix and move faster, thus higher diffusion rate.

An isotope has 15 protons, 16 neutrons, and 15 electrons. What is the isotopic notation of the isotope
VikaD [51]

Answer:

^{31}_{15}P is the isotopic notation of the atom

Explanation:

The isotope notation is:

^a_bX

<em>Where a is the mass number = Number of protons + Number of neutrons</em>

<em>b is atomic number = Number of protons</em>

The atomic number define the nature of the atom, the element with atomic number = 15 is phosphorus, P:

^a_bP

a = 15 protons + 16 neutrons = 31

b = 15

^{31}_{15}P is the isotopic notation of the atom.

What term best defines the process that occurs when nuclei combine to produce a nucleus with more mass?
bekas [8.4K]
I just answered your other question and wrote all the definitions of the terms. I would say this is probably refering to Fusion because you are fusing together more nuclei into one nucleus. Fusion= bringing separate things into one entity.

How does the kinetic molecular theory explain the fact that gases condense into liquids?
Elenna [48]
<h3><u>Condensation of gases into liquids by kinetic molecular theory:</u></h3>

The "kinetic molecular theory" explains the states of matter based on the matter composed of very tiny little particles that are constantly in motion. The theory also explains the observable properties and behaviors of solids, liquids, and gases.

Condensation of particles of a real gas to form liquid is due to the attractive forces present in between them. During the condensation process, gas molecules slows down and come together to form a liquid.  And also during the transfer of energy to something cooler, the process slows down and they attract the bond to become liquid.  Each particle motion is completely independent. The kinetic energy of gas particles is dependent on the temperature of the gas.
