Question 1: Should acid precipitation be a concern for the new age environmentalist?

1 answer:

6 0

Acid precipitation should be a concern for the new age environmentalist, as they are one of the many consequences of a polluted and warming world, such is the one we live in. Acid precipitation comes from the evaporation of acid sea water, due to global warming and the fact that when more heat is trapped into the sea, more acid substance are released.

It can be answered by science because it is a question that is been solved via some experiments and it is in fact been proven recently as proofs correlates global waming with the acidification of the ocean and then acid rain. So this is a physic and environmental question, with ramification and consequences in other fields of science.

Acid precipitation in forests could affect the reproduction rate in birds. There are multiple factor that affect the reproduction rate in birds, and environment is one of the most complex and yet undiscovered. The two could have a potential entaglement as, for hyphotesis, acid precipitation could cause certain plant to die, and than the birds do not have a place where to reproduce.

It can be answered by science, via experiments and study. The relationship between environment and biology is a well-know correlation, so it does not represent a strech in this sense. Moreover, while it could be difficult to assure this for different reason, this is a problem that science could solve in different ways.

The expected o-c-h angle in this molecule is degrees. the expected hybridization at the central carbon is

WINSTONCH [101]

Each neutral carbon atom contains four valence electrons and may form up to four electron domains. Possible hybridizations include

$sp^{3}$ , four electron domains, as in ethane $\text{C}_2\text{H}_6$
$sp^{2}$ , three electron domains, as in ethene $\text{C}_2\text{H}_4$
$sp$ , two electron domains, as in ethyne $\text{C}_2\text{H}_2$

Molecules of each of the three hybridization demonstrate spatial configurations that would maximizes the separation between the electron domains.

Carbon atoms with a $sp^{3}$ hybridization would demonstrate a tetrahedral configuration with a bond angle of approximately $109.5\textdegree{}$
Carbon atoms with a $sp^{2}$ hybridization would demonstrate a triangular planar configuration with a bond angle of $120\textdegree{}$
Carbon atoms with a $sp$ hybridization would demonstrate a linear configuration with a bond angle of $180\textdegree{}$

Bond angles are characteristic of the spatial configuration of electron domains and identifies the hybridization of the central carbon atom.

Note that each hydrogen atom contains only one valence electron and would form only single bonds. It takes two valence electrons for oxygen atoms to achieve an octet such that each oxygen form only two bonds at a single time. Therefore given the fact that the carbon is bonded to both hydrogen and oxygen, only the following hybridizations are possible

$sp^{3}$ in which the oxygen atom forms a carbon-oxygen double bond with the central carbon atom;
$sp^{2}$ in which the oxygen atom forms a single bond with the central carbon atom and with a second atom.

Malic acid, C4H6O5, has been isolated from apples. Because this compound reacts with 2 molar equivalents of base, it is a dicarb

Flura [38]

Answer and explanation:

The attached figure shows five different structures for the chemical formula C4H5O5, but only one of these structures represent the malic acid.

Malic acid is a dicarboxylic acid, this means malic acid has two

-COOH groups. Also, malic acid is a secundary alcohol, which means it has a R2-C-OH group.

-Structure A has two carboxylic groups, but it doesn´t have a secundary alcohol.

-Structure B doesn´t have any caborxylic group.

-Structure C has two carboxylic groups and it is a secundary alcohol. Structure C is the Malic acid

How many moles of n are in 0.163 g of n2o?

zimovet [89]

First convert 0.163 grams of N2O to mol by dividing it with the molecular weight. The molecular weight of N2O is 44 grams/mol. The answer would be 3,79x10^-3. Then multiply it with 2 since there are 2 Nitrogen in one mole of N2O. Therefore, there are 7.41x10^-3 moles of Nitrogen.
