Answer:
5.27*10^23 (rounded to 3 significant figures)
Explanation:
The amount of molecules in one mole of anything is equal to Avogadro's number: 6.022×10^23
To find the number of moles of NaOH in 35 grams of it, do 35 divided by the molar mass (39.997): 35/39.997=0.87506562 moles of NaOH
To find the number of molecules, multiply the moles of NaOH by Avogadro's number: 0.87506562×(6.022×10^23)=5.26964522*10^23
Answer: The movement of heat from a warmer object to a cooler one is called heat transfer
Explanation:
Answer:
I believe your answer will be 3--
As the fuel burns, chemical reactions occur within the fuel, breaking up molecules, forming new molecules, and releasing energy. The energy is released as heat, and allows parts of the engine to move. The chemical energy is transformed into thermal energy.
Explanation:
Hope this helps you!!!
1) list givens and convert if necessary
C₁ = 3.50 mol/L
V₁ = 0.550 L
C₂ = ?
V₂ = 0.275 L
2) rearrange formula
3) solve
C₂ = 7.00 mol/L
