Some rocks contain carbonate minerals, and the acid test can be used to help identify them.
I don't understand what is (g).
Maybe the answer is 2H<span>(aq)S</span>₂<span>−2(aq) </span>⇒ <span>H</span>₂<span>S</span>₂.
Answer: 0.8g/cm^3
Explanation:
In seeing your problem, I see an issue with your units for centimeter. The volume is in the third dimension, so we use cm^3 every single time for the volume. That way, we can arrive to the correct density (in g/cm^3)
Density = mass/volume and so
Density = 8g/10cm^3
= 0.8g/cm^3
Explanation:
momentum increases with an increase in mass and velocity
Answer:
s orbitals - spherical shape
p orbitals - dumbbell shape
d orbitals- dxy, dyz , dzx -double dumbbell
- dx²-y²- double dumbbell (along axis)
-dz² -dumbbell with electron cloud
( along the axis)
therefore here the answer is 2s and 3s
