Filtering helps produceclean water by...
Explanation/summary/reasons:
Filtering dirty water can take away the tap water odor, heavy metals, bacteria and dirt that can cause a person to get infected or sick. Filtering can even remove the chloride inside the dirty water and reduces limescale and acid reflux and can make clean water have anti-oxidant properties in it. Filtered and clean water is better for the environment and healthier by improving skin health and healthier for making tea,coffee and healthier smoothies. Water can also enhance hydration, energy, helps get rid of headaches, reduces cardio stress and improves digestion. It even saves more money from your wallet as well!

KOH(aq) + HCl(aq)==> ________ +________
Compare the number of moles of H+(aq) ions to the number of moles of OH-(aq) ions in the titration mixture when the HCl(aq) is exactly neutralized by the KOH(aq).
Determine the concentration of the KOH(aq).

Answer:
Explanation:
According to molecular kinetic theory, 1) gas particles (molecules or atoms) occupy a negligible fraction of the total volume of the gas, and 2) the force of attraction between gas molecules is zero.
Those two assumptions constitute the basis for the behavior of a gas and an ideal gas.
The lower the pressure and the higher the temperature the closer those assumptions are valid for real gases.
At low pressure, the particles of the gas will be more separated from each other and so the tiny volume they occupy will be a smaller fraction of the total volume.
At higher temperatures, the particles will have more kinetic energy, which means that they will have larger average speed, and so the forces between the molecules will count less.
So, you conclude that under low pressure and high temperatures a real gas is most likely to behave ideally.
Answer: The given statement is false.
Explanation:
When there is more difference in the ratio or number of protons and neutrons then nucleus of the atom becomes unstable in nature. This unstability is caused due to greater repulsion between the like charges of sub-atomic particles.
As a result, this force of repulsion becomes greater than the binding energy. And, this force is known as the weak force because it is unable to bind the neutrons and protons together.
The proton and neutron ratio for smaller elements is 1:1 and for higher elements it has to be 1:5. Since, is a smaller element with 4 protons and 4 neutrons. Hence, the proton and neutron ratio is 1:1.
Therefore, is stable in nature.
Thus, we can conclude that the statement nucleus of 8Be, which consists of four protons and four neutrons, is very unstable and spontaneously breaks into two alpha particles (helium nuclei, each consisting of two protons and two neutrons), is false.
