We have that the percentage of SPT (3.10 g/mL) present in a solution with a density of 2.60 g/mL is
Percentage of spt=2\%
From the question we are told
What percent of SPT (3.10 g/mL) is present in a solution with a density of 2.60 g/mL, suitable to separate quartz and feldspar? The other component of this solution is water (1.00 g/mL)
Generally the equation for the Desired SPT is mathematically given as
Where
Density of Quartz is Generally given as 2.7g/ml
Therefore
Therefore
Percentage of spt=0.02*100
Percentage of spt=2\%

The Answer would be C. Without plants in the ecosystem, it could not feed. Plants are mainly the only producers that feed 3rd level consumers which feed 2nd level consumers which feed 1st level consumers.
Iodine react with nitric acid to produce iodic acid, nitrogen dioxide and water.
Answer:
a) N2 (g) + H2 = 2 NH3
b) You have to state the mass of hydrogen
Answer:
* The empirical formula of a compound shows the ratio of elements present in a compound
* The molecular formula of a compound shows how many atoms of each element are present in a molecule of a compound.
Example: the compound butene has a molecular formula of C4H8. The empirical formula
of butene is CH2 because there is a 1:2 ratio of carbon atoms to hydrogen atoms.
