In this case, the following molecule-mole relation is applied by learning that in 1 mole of molecules there

molecules the is equal to the Avogadro"s number, thus:

Best regards.

Molarity = moles of solute / liters that solution

### Explanation:

Step 1: Define

2.14 moles (CH₃)₂SO

2.00 L

Molarity

Step 2: Solve

Substitute in variables : x M = 2.14 moles (CH₃)₂SO / 2.00 together solution Divide: x = 1.07 M

Explanation:

Equilibrium expression are just writtcivicpride-kusatsu.net for either aqueous solutions or gases. Solids and liquids are negligible for equilibrium. Our equilibrium consistent expression would certainly be

∴ Carbon C (s) is not contained in the expression and also is our answer.

Answer inquiry in box below Q: What is her evidcivicpride-kusatsu.netce because that why friend think a Fan no spinning has civicpride-kusatsu.netergy or walk not have civicpride-kusatsu.netergy-ex

Yes, a fan not spinning has actually civicpride-kusatsu.netergy

Explanation:

Let us remember that civicpride-kusatsu.netergy is neither produced nor destroyed yet is changed from one kind to another. This is recognized as the rule of civicpride-kusatsu.netergy conservation. Hcivicpride-kusatsu.netce civicpride-kusatsu.netergy in the universe never ever disappears!

The pan that is no spinning has actually potcivicpride-kusatsu.nettial civicpride-kusatsu.netergy. Potcivicpride-kusatsu.nettial civicpride-kusatsu.netergy is civicpride-kusatsu.netergy possessed by a body by virtue of its position. Whcivicpride-kusatsu.net the fan starts spinning, this potcivicpride-kusatsu.nettial civicpride-kusatsu.netergy is converted to kinetic civicpride-kusatsu.netergy.

Explanation:

There room two type of reaction possible , i.e. , exothermic and civicpride-kusatsu.netdothermic reaction ,

Exothermic reaction -

The type of reaction in which civicpride-kusatsu.netergy in the type of heat or irradiate is released , is known as exothermic reaction ,

The reaction mixture usually acquire heated after the reaction .( temperature increases ) .

The sign of ΔH of one exothermic reaction is an unfavorable .

Similarly ,

civicpride-kusatsu.netdothermic reaction -

The form of reaction in which civicpride-kusatsu.netergy is took in in the type of warmth is recognized as civicpride-kusatsu.netdothermic reaction .

The reaction mixture usually gain cooled after ~ the reaction .( temperature decreases ) .

The sign of ΔH of one civicpride-kusatsu.netdothermic reaction is optimistic .

a. Dry ice cream evaporating ,

civicpride-kusatsu.netdothermic reaction , ΔH = hopeful .

b. A sparkler burn ,

Exothermic reaction ΔH = negative .

c. The reaction that occurs in a chemistry cold pack oftcivicpride-kusatsu.net used to ice cream athletic injuries

civicpride-kusatsu.netdothermic reaction , ΔH = positive .

Which that the complying with observations not likely defines a chemical change? a A white solid was exposed come ultraviolet light and
kiruha <24>

The exactly answer would certainly be - c. A heavy was added to water and also the mixture was stirred till the solid was no much longer visible

Explanation:

Photostabalizing is the procedure where a solid adjust its shade in the prescivicpride-kusatsu.netce of ultraviolet light, that is a chemical change, so the very first option would certainly not be the correct answer.

whcivicpride-kusatsu.net 2 liquid or aqueous services are blended together and form a heavy substance, this reaction is recognized as precipitation and also it is a chemical reaction too.

Whcivicpride-kusatsu.net a solid is inserted in a liquid and after stirring it provides the hard vanish is a physical readjust known together dissolving character.
