Number 2 is 4 states they are condensation freezing melting and evaporation
Answer: 26.25 miles per gallon
Explanation: first odometer reading = 65290
Second odometer reading = 65500
Difference in odometer reading = second reading - first reading
= 65500 - 65290 = 210 miles.
If it took 8 gallons to fill his tank, it means
8 gallons will get him 210 miles, therefore 1 gallon will get 210 miles/8gallons = 26.25miles/gallon. Hence he is getting 26.25miles/gallon.
First, we write the reaction equation for the formation of HCl from hydrogen and chlorine:
H₂ + Cl₂ → 2HCl
Now, we substitute the values of the enthalpies, denoting that of the Cl-Cl bond by x:
435 + x = -92 + 2(431)
x = 335
The bond dissociation enthalpy for the Cl-Cl bond is 335 kJ/mol
Answer:
weak bonds require less energy to form bonds than strong bonds
Answer:
See explaination
Explanation:
Lewis structures, which is also called electron-dot structures or electron-dot diagrams, are diagrams that show the bonding between atoms of a molecule, and the lone pairs of electrons that may exist in the molecule. A Lewis structure can be drawn for any covalently-bonded molecule, as well as coordination compounds.
