Answer:
Dmitri Mendeleev=Russian chemist, Albert Ghiorso=American scientist
Explanation:
Answer:
106 mL
Explanation:
In order to be able to answer this question, you must understand what the density of a substance tells you.
The density of a substance is nothing more than the mass of that substance that occupies one unit of volume.
In your case, the density of ethanol is given in Grams per milliliter, which means that one unit of volume will be
1 mL
.
So, ethanol has a density of
0.785 g mL
−
1
, which is equivalent to saying that if you take exactly
1 mL
of ethanol and weigh it, you will end up with a mass of
0.785 g
.
Now, you know that the volume you're using has a mass of
83.3 g
. Well, if you get
0.785 g
for every
1 mL
of ethanol, it follows that this much mass will correspond to a volume of
83.3
g ethanol
⋅
ethanol's density
1 mL
0.785
g ethanol
=
106.11 mL
Rounded to three sig figs, the answer will be
V
ethanol
=
106 mL

The sea level would rise by some 50 meters.
Explanation:
If the earth's temperature increases by 3 degrees the north and south pole would experience the ice melt at high speed.
The life will get difficult on the plains.
The extinction of some species will happen.
The sea level would rise by 50 meters. The increased sea level will cause depletion of habitat from plants and animals.
The floods will occur, land erosion, soil for agriculture land will get contaminated with the salt.
