Answer:
Mechanical weathering
A. does not change rock composition
C. abrasion
F. ice wedging
Chemical weathering
B. oxidabon
D. changes rock composition
E. acid rain
Explanation:
From the conversion of units:
1 cm^3 is equivalent to 1 mL
1 L is equivalent to 1000 mL
therefore,
to convert from liter to cm^3, we simply multiply by 1000.
Note that the multiplication will be done in the denominator.
Based on this:
density = (0.625 g/l) x (1g/1000 cm^3) = <span> 0.000625 g/cm^3
= 6.25 x 10^-4 g/cm^3</span>
Answer:
mass gives the mass of atoms while molecular weight gives the mass of molecules
Answer:
The mass density will be doubled
Explanation:
- Density is given by dividing the mass of a substance by its volume.
- An increase in mass causes an increase in density and vice versa, while a decrease in volume causes an increase in density and volume.
- Therefore, when the volume is halved, then the density will be doubled if the mass is kept constant.
- This has no effect on the number of moles as the mass is constant.
