Answer:
True water is wet because when something is wet in this case it's water it has water on it at a molecular level. Water molecules are bonded on top of each other so it's wet.
Answer:
According to avogadro's law, 1 mole of every substance contains avogadro's number
of particles and weighs equal to its molecular mass.
To calculate the moles, we use the equation:
a. moles in 14.08 g of
= 
molecules in 14.08 g of
= 
b. moles in 17.75 g of NaCl = 
molecules in 17.75 g of
= 
formula units 17.75 g of
= 
c. moles in 20.06 g of
= 
formula units in 20.06 g of
= 
A physical property does not change the substance.
Solubility would be the answer since all of the rest are changing the substance. They all deal with bonds except solubility.
Answer: D. Solubility
The balanced reaction
that describes the reaction between carbon monoxide and oxygen to produce
carbon dioxide is expressed co(g)+ ½o2(g) <span>→ </span>co2(g). The heat of combustion is 67.6 kcal per mole CO. We are given with 14 grams CO. Convert this to mole equal to 0.5 mole. Hence the total heat is 33.8 kcal.
