The density of rubbing alcohol is 0.785g/mL at 25℃.

1 answer:

5 0

Answer: The temperature is there to confuse you on purpose. Density changes with temp, but in these type of problems, they mean nothing

Explanation:

The formula for density is mass per unit of volume.

$D=m/v$

We dont have to do any conversions here so it boils down to division and multiplication.

$0.785g/mL=mass/15mL\\0.785g/mL*15mL = mass\\=11.78 grams$

Now for the second part:

$0.785g/mL=15g/volume\\15g/0.785g/mL = volume\\=19.11mL$

What happens to electrons in ionic bonds?

vlabodo [156]

Answer:

Ionic bonding is the complete transfer of valence electron(s) between atoms. It is a type of chemical bond that generates two oppositely charged ions. In ionic bonds, the metal loses electrons to become a positively charged cation, whereas the nonmetal accepts those electrons to become a negatively charged anion.
