I think it is B, but i am not sure
Answer:
Explanation:
The two carbon atoms would be different. These different carbon isotopes are called isotopes. Isotopy is the existence of two or more atoms of the same element having the same atomic number but different mass number due to the difference in the number of neutrons in their various nuclei.
Carbon for example has 3 known isotopes which are:
¹²₆C ¹³₆C ¹⁴₆C
These isotopes have different places in nature where they can be found. Some can occur together naturally.
Isotopes have the same chemical properties because they share similar electronic configuration.
The bubbles are Carbon dioxide gas
Is the C because the mass in the compound is correct
Explanation:
Use the density formula to determine the volume of the piece of metal.
density
=
mass
volume
Rearrange the equation to isolate volume.
volume
=
mass
density
volume
=
147
g
7.00
g
mL
=
21.0 mL
The final volume in the cylinder after adding the piece of metal is
20.0 mL
+
21.0 mL
=
41.0 mL
