Answer:
The density of copper is 0.5 g/mL
Explanation:
Given data:
Mass of copper = 6 g
Volume of copper = 12 mL
Density of copper = ?
Solution:
Formula:
d = m/v
d = density
m = mass
v = volume
d = 6 g/ 12 mL
d = 0.5 g/mL
Thus, the density of copper is 0.5 g/mL
They are called isotopes.
Example of isotopes are Hydrogen and deuterium.
Hydrogen is 1 proton and 0 neutrons.
Deuterium is 1 proton and 1 neutron
Gasses is the one because gas and gasses
A polymer is a really long chain of smaller molecules (monomers). It's similar to a chain of paper clips because all of the little monomers will attach to each other, forming a long strain.
Answer:
The answer to your question is: b. P - Br
Explanation:
Difference of electronegativities from the periodic table. The one with the highest electronegativity will be the most polar.
a.
H = 2.2
Se = 2.55
Electronegativity = 2.55 - 2.2 = 0.35
b.
P = 2.19
Br = 2.96
Electronegativity = 2.96 - 2.19 = 0.77
c.
N = 3.04
I = 2.66
Electronegativity = 3.04 - 2.66 = 0.38
