An abandoned Indiana coal mine spoil bank (wastes) contains chunks of pyrite minerals. Under constant erosion and weathering, th

e pyrites leach large amounts of sulfuric acid (H2SO4). The spoil banks are also mixed with large quantities of basic limestone and clay carbonates. What should occur over time?

Answer:

The acid will be neutralized overtime

Explanation:

The presence of the pyrites leads to the leaching of large amounts of sulphuric acid, however the basic carbonates neutralizes the acid according to the reaction equation;

CaCO3 + H2SO4 ---> CaSO4 + CO2 + H2O.

This will prevent all the deleterious consequences associated with the leaching of the acid in the abandoned coal mine.

Please help me I have not gone over this in like 8 months and can not remember how to do it
Leona [35]

Answer:

91%

Explanation:

Since you are just trying to find the yield, take the moles of the substance from the products and divide it by the mol value of the reactants. Multiply by 100 to find percentage

0.45 ÷ 0.41 = 0.91111...

Generally speaking, which group would have the lowest electronegativity values in a period?
dezoksy [38]

Answer: Group 1 would have the lowest electronegativity values.

Explanation:

Electronegativity is the power of an atom in a molecule to attract electrons. It is also synonymous with the oxidizing ability or non-metallic character of elements.

Generally, across a given period from left to right, electronegativity increases due to increasing nuclear charge and decreasing atomic radius ( or atomic size ). This is because there is a greater tendency for a smaller atom with higher nuclear attraction to attract electrons than a larger atom with a lower nuclear attraction due to the shielding effect of the nuclear attraction by the inner shell electrons on the outermost electrons in the larger atom.

Also, down a particular group, electronegativity generally decreases due to increasing atomic radius/size.

This is why metals are generally electropositive ( lose electrons ) and non-metals are electronegative ( gain electrons ) as they are both found more on the left and right sides of the periodic table respectively.
