Answer:
Sound waves transfer energy by the motion of particles
Explanation: guessing lol
The answer is that exact locations within either cannot be determined at any given moment in time.
An electron cloud be compared with a spinning airplane propeller in the manner that in both exact location within either cannot be determined at any given moment in time.
In both electron cloud as well as spinning airplane propeller, there is a probability of finding either but exact location can not be determined.
Because of a cold from moved into the aira
and the weather hit 32 and it snowed
There are 618.68 g in 4.5 moles of NaF.
The total number of moles of any substance equals the ratio of its given mass in a chemical reaction to the mass of one mole or molar mass of that substance.
It is known that one mole of NaF or molar mass of NaF is 41.98 g/mol.
Given that number of moles is 4.5 moles.
Therefore, calculate the mass of NaF in grams as follows.
No. of moles = Given mass / Molar mass
mass in grams = No. of moles × Molar mass
= 4.5moles × 41.98 g/mol
= 188.91 g
Hence, we can conclude that there are 188.91 g in 4.5 moles of NaF.

Answer:
Mrs. Nogaki is right because Mr. Holmes’s BBQ produces 3x more CO2 for each mole of fuel burned.
Explanation:
Now Mrs. Nogaki has already figured out the chemical combustion reaction behind the operation of her BBQ. It is pertinent to reproduce it here.
CH4(g) + 2O2(g)→CO2(g) +2H2O(g)
She already has this figured out but Mr. Holmes doesn't have any chemical reaction equation to back his claims. Let us help him with the correct combustion equation for propane.
C3H8(g) + 5O2(g) + 3CO2(g) + 4H2O(g)
We can clearly see from the reaction equation that Mr. Holmes BBQ produces three times more carbon IV oxide than Mr. Nogaki's BBQ so Mr. Nogaki was right in her claim after all.
Hence the answer!
