The ion responsible is HCO3-. HCO3- is the conjugate base of the weak acid H2CO3 and ionizes in water: HCO3- + H2O <=> H2CO3 + OH- Since OH- ions are produced by the hydrolysis, [OH-] > [H+] and the water is basic (pH > 7). Solution The ion responsible is HCO3-. HCO3- is the conjugate base of the weak acid H2CO3 and ionizes in water: HCO3- + H2O <=> H2CO3 + OH- Since OH- ions are produced by the hydrolysis, [OH-] > [H+] and the water is basic (pH > 7)..

Phenanthrene is a polycyclic aromatic hydrocarbon composed of three fused benzene rings. The name phenanthrene is a composite of phenyl and anthracene. In its pure form, it is found in cigarette smoke and is a known irritant, photosensitizing skin to light A classical phenanthrene synthesis is the Bardhan-Sengupta phenanthrene synthesis. Phenanthrene is nearly insoluble in water but is soluble in most organic solvents such astoluene,carbon tetrachloride,ether,chloroform,acetic acidandbenzene. The first step is an electrophilic aromatic substitution reaction, which is allowed when the diphosphorous pentoxide makes the alcohol a better leaving group. However, no alkenes outside of the initial aromatic ring are created. In the second step of this reaction 9,10- dihydrophenanthrene is oxidized with elemental selenium. The aromatization of six-membered rings by selenium is not clearly understood, but it does produce H2Se. Phenanthrene can also be obtained photochemically from certain diarylethenes. Reactions of phenanthrene typically occur at the 9 and 10 positions, including: Organic oxidation to phenanthrenequinone with chromic acid Organic reduction to[9,10-dihydrophenanthrene with hydrogen gas and raney nickel Electrophilic halogenation to 9-bromophenanthrene with bromine Aromatic sulfonation to 2 and 3-phenanthrenesulfonic acids with sulfuric acid Ozonolysis to diphenylaldehyde Canonical forms Phenanthrene is more stable than its linear isomer anthracene. A classic and well established explanation is based on Clar\'s rule. A novel theory invokes so-called stabilizing hydrogen- hydrogen bonds between the C4 and C5 hydrogen atoms. Natural occurrence Ravatite is a natural analog of synthetic phenanthrene. It is found in small amounts among a few coal burning sites. Ravatite represents a small group of organic minerals.

Yes both men and women differ in their thinking, research has proved that women brain used ten times more white matter when compared to men, this makes females multi tasking and can go for quick transition between tasks. When it comes to males, they use seven times more gray matter when compared to female from their activity and the gray matter is involved in information storing and action processing and this makes men to do better when given task focused projects. Bothe men and women shows differences in thinking, social behavior, and personality as they both process the same neurochemicals in different degrees (serotonin is one dominant neurochemical). This will make women more patient, can sit for long time, will not be stressed frequently and females will have absorb more emotive and even the sensorial information when compared to males due to their larger hippocampus (memory center) like women can sense or guess what is going on surrounding her. Due to influence right and left hemisphere, girls will be more in discussion with more different words and can express their feelings well and can adapt to the situation in a better way. Females will have more problem solving capacity. Females tend to show less aggressive behavior and they will calm and quiet and follow tend and befriend strategy. Men tend to be more aggressive and will not have adjustment attitude and follow the fight or flight response towards the stress situation. Yes the differences between men and women are significant. As we know conventional wisdom is what is generally accepted by everyone, commonsense is nothing but what you feel or understand by seeing or perceiving things. Men will try to understand and perceive things on their own by analyzing the things, but women will tend to go with common understanding what everyone is having about the issue.

What is the probability that a five-card poker hand contains the ace of hearts? Solution P(getting the ace of heart in 5 cards) = P(1st is AH or 2nd is AH or 3rd is AH or ... or 5th is AH) Since these event are mutually exclusive (getting one excludes the others from happening), then you can just add the probabilities. = P(1st is AH) + P(2nd is AH) + ... + P(5th is AH) = 1/52 + 1/52 + ... + 1/52 (note that these are unconditional probabilities, so all are 1/52) = 5/52 = 0.096153846.

In incomplete dominance- no complete dominance if any particular gene over the other. So in between of two phenotype we get a phenotype of pink colour and neither red not white. If Rr×Rr in complete dominance RR- red, 2Rr- red, RR- white. Hallo sufficiency as one copy of gene is enough to maintain the character. In incomplete dominance- RR- red, 2Rr- pink, RR- white.

The racial and ethnic makeup of the American people is in flux. New immigrants from Asia and Latin America have added a large measure of cultural and phenotypic diversity to the American population in recent decades, just as waves of immigrants from Southern and Eastern Europe did a century ago. Moreover, the boundaries between racial and ethnic groups are becoming blurred by high rates of intermarriage and the growing number of persons with mixed ancestry. Descriptions and projections of the racial and ethnic composition of the American people appear kaleidoscopic, with varied accounts and interpretations. Some commentators anticipate a new melting pot, often labeled as the “browning of America,” characterized by continued blurring of once-distinct racial and ethnic divisions. This interpretation is consistent with the thesis of the declining significance of race and ethnicity in American society. Others see new racial divisions arising as some immigrant groups are allowed to integrate with an expanded and privileged white population, while other groups are “racialized” as disadvantaged brown and black minorities. These conflicting accounts arise, in part, because of differing ideological presuppositions, but also because racial and ethnic identities are not mutually exclusive or immutable. . In general, people do not change their ethnicities as a matter of fashion, but they may emphasize different aspects depending on the circumstances. For instance, a person who identifies as Mexican among relatives might identify as Hispanic at work and as American when overseas. A person of mixed heritage might be Native American in one context, but white in another. These possibilities exist in census data, just as they do in informal conversations and settings, because of the opportunities for varied responses to different census questions about race and ethnicity.

Physical changes are those that do not change the identity of the chemical undergoing the change. Thus, physical changes include: 1. Ice melting to water (the material is still H2O) 2. water boiling to form steam (again, still H2O) 3. dry ice subliming to form carbon dioxide gas (still CO2) 4. tearing a piece of paper in half (still paper) 5. salt precipitating from a super saturated solution (NaCl) 6. carbon dioxide fizzing out of a soda (still CO2). Chemical changes, however lead to changes in the chemical structures and identities of the materials: 1. Burning paper to form CO2 and water 2. Reacting sodium metal with water to form H2 and NaOH 3. Cooking sugar to make caramel 4. An iron nail rusting 5. reacting an acid (such as vinegar) with a base (such as ammonia) 6. photosynthesis - carbon dioxide and water converted to sugar + oxygen.
