<u>Answer</u>: c. a and b
Trees play vital roles in the production of oxygen as well as the fixation of carbon from . As trees use nitrogen, phosphorus and water as nutrients for growth, their diminishing numbers would change the balance between these three elements significantly.
Thus, during rains, the water level will rise much faster and higher in the absence of trees. These could possibly lead to increasing cases of devastating landslides.
the specific gravity of pure sulfuric acid is---------> approximately 1.835 g / cm3
the specific gravity of water is -------------------- >1.000 g / cm3.
The electrolyte, that is, the dissolution of sulfuric acid in water, is usually at a rate of 36% acid, so that, in a fully charged element, we can deduce the electrolyte density, is 1.295 g / cm3. (see attached table)
The specific gravity is actually the difference in the weight of water compared to a specific fluid. It is measured with a hydrometer
