Kinetic Energy Statement
Kinetic energy is energy that a body possess as a result of its motion. Kinetic energy as it is mathematically written is the "classic statement" of: Kinetic energy is equal to half the mass of an object times its velocity squared.
There are five types of kinetic energy: radiant, thermal, sound, electrical and mechanical. Let us look at some of the kinetic energy examples and learn more about the different types of kinetic energy.

To test for hydrogen, burn a candle near the suspected source of hydrogen. If you hear a squeaky pop sound, hydrogen is present because when hydrogen gas burns, it makes a squeaky pop sound.
Hypertonic" is the one among the following choices given in the question that is a solution used for salad dressing.
Explanation:
A hypertonic solution is a special type of solution that has a greater concentration of solutes on the outside of a cell when associated with the inside of a cell.as a result, water inside the cell will move outwards to attain equilibrium, creating the cell to shrink.
Answer:
106.6 °C
Step-by-step explanation:
The formula for <em>boiling point elevation</em> ΔTb is
ΔTb = iKb·b
where
i = the van't Hoff i# factor
Kb = the molal boiling point elevation constant
b = the molal concentration of the solution
=====
<em>Data
</em>
i = 2, because 1 mol of NaCl gives 2 mol of ions in solution.
Kb = 0.51 °C·mol·kg⁻¹
b = 1.00/0.155
b = 6.452 mol·kg⁻¹
=====
<em>Calculations
</em>
ΔTb = 2 × 0.51 × 6.452
ΔTb = 6.58°C
Tb = Tb° + ΔTb
Tb = 100 + 6.58
Tb = 106.6 °C
Answer:
The systematic name of the complex is: ![[Cu(en)_2(H_2O)_2]I_2](https://tex.z-dn.net/?f=%5BCu%28en%29_2%28H_2O%29_2%5DI_2)
diaquabisethylenediaminecopper(II) iodide
Explanation:
= Given complex whose naming is to be done:
Rules for naming of the coordination compounds :
- The name of ligand should be written first and then metal.
- The charge of metal indicated with the Roman numerals and enclosed in the parenthesis after metal name.
- The ligand's names written should be in an alphabetical order before the metal ion.
- Ligands that include a numerical prefix in the name use the prefixes bis or dia for 2, tris for 3, or tetrakis for 4 to indicate their number.
- If the complex ion is an anion, we drop the ending of the metal name and add –ate.
The cationic part of the complex: diaquabisethylenediamine copper(II)
The anionic part of the complex: iodide
The systematic name of the complex is:
diaquabisethylenediaminecopper(II) iodide
