Smaller numbers mean less risk of losing, but less chance of gain, Volatility.
What is gain?In electronics, gain is a measure of the ability of a two-terminal circuit (often an amplifier) to increase the power or amplitude of a signal from its input. Adjusting the gain control sets the amount of distortion in the sound no matter how loud the final volume is set. This means that the gain setting determines how clean or dirty the sound is, regardless of the master volume setting.Gain is simply the amplification factor, i.e. the parts of the output power to input power. Wins are often expressed in percentages, especially for small wins. Example 3% of ratio signifies to a power gain of 1.03.to learn more about gain from the given link:

Water is the most abundant atom is a false statement.
Water molecule is composed of two hydrogen atoms and one oxygen atom. Water is necessary for the survival of living organisms. Water is polar because the oxygen atom in water has a higher electronegativity than the hydrogen atoms, resulting in a partial negative charge on the oxygen atom and partial positive charges on the hydrogen atoms.
Water stabilizes temperature because it has a high heat capacity, meaning it can absorb or release a large amount of heat without experiencing a significant change in temperature.

Explain the reaction of sodium hydroxide with water?Whenever sodium hydroxide (NaOH) reacts with water, sodium ions (cations) with a positive charge and hydroxide ions with a negative charge separate out (anions).
Although cations and anions typically surround cations more tightly and vice versa, these ions move freely and independently of one another in the water.
NaOH easily absorbs moisture as well as carbon dioxide through the air because to its high water solubility.Solid sodium hydroxide dissolves in water in an extremely exothermic reaction that releases a significant quantity of heat.The following response is being thought about:NaOH(s) + H2O(l) => Na+ + OH- + H20 + HEAT
This is the sodium hydroxide dissolving in water, not a reaction. You must ascertain the solvation's enthalpy, Hsol. Due to the exothermic nature of the process, this is bad.You must be aware that Na+ and OH- interact ionically.Since, you've solubilized NaOH, the Na+ cations and OH- ions have strong interactions with the oxygen and hydrogen atoms in the water.

The bones of a saber-toothed tiger are found to have an activity per gram of carbon that is 15.0 % of what would be found in a similar live animal. How old are these bones? Give answer in years. Do not enter unit.
The bones are 16925 years old.
The process of carbon dating involves counting the amount of the radioactive isotope carbon-14 that is present in a sample. As carbon-14 breaks down into nitrogen-14 over time, less of it is present. Scientists can determine how recently an organism died by calculating the ratio of carbon-14 to carbon-12 in a sample. Now to know the age of the bones we must directly use the radioactive decay law: d N d t ∝ N
Where the rightmost part of the equation comes from the statement that the activity found is just 15.0% of the activity that would be found in a similar live animal. This means that the number of carbon-14 atoms is just 15.0% of what it was at the moment the saber-toothed tiger died.
