Answer:
Explanation:
you know density and volume fromt he equation you have to caclaute the mass
density = mass / volume
density * volume= mass
0.790*30 = mass
23.7 g= mass
he need to weigh around 23.7 g of acetone
The atoms under this question can be found elsewhere and as follows:
chlorine (Cl) - 3.61
sulfur (S) - 2.58
hydrogen (H) - 2.2
oxygen (O)- 3.44
<span>fluorine (F)- 4
</span>
<span>Based on difference in electronegativities between atoms, the most polar bond pair would be hydrogen and fluorine. They have the highest electronegativity difference.</span>
The statement is false. We know this beause this principle states that impossible for two electrons to have the same four electronic quantums. Remember that the orbtials can each have only two electrons max.

Answer:
68.6 m
Explanation:
Speed is defined as distance covered per unit time and expressed as
S=d/t
Where d is distance and t is speed.
Making d the subject of the above formula then
d=st
Substituting 343 m/s dor s and 0.200 s for s then
d=343*0.2=68.6 m
Therefore, the distance is 68.6 m
