kcl is the salt koh is the base
Answer:
phenotype,phenotype,genotype,genotype,
genotype
Explanation:
phenotype is physical appearance and genotype is just like
yy Tt
Answer:
0.3mol C8H18
Explanation:
For this we must first look at the reaction taking place:
C8H18+O2 --> H2O + CO2
Balancing the equation we get:
2(C8H18)+25(O2) --> 18(H2O) + 16(CO2)
Form there we now need to know how many moles of Octane are needed to produce 2.4moles of H2O. The conversion is as follows:
2.4molH2O ((2mol of C8H18)/(18mol of H2O)) = 0.3mol C8H18
5= Both parents must both be Heterozygous (Ee) because they have unattached earlobes but can still produce offsprings with attached earlobes because they still possess the recessive gene (e).
6=Punnett Square: (top right)-tt, (bottom right)-tt. Genotypes= Tt, Tt, tt, tt. Phenotypes= Roller(Tt), Roller(Tt), unable to roll(tt), unable to roll(tt).
Answer:
Is a substance that can maintain certain range of pH
Explanation:
A buffer is mixture of two salts that are complementary, one salt is acid and another is basic, but since then share some part of their structure, if you add to this mixture another acid, the basic salt can absorb it and still maintaining the same pH. If you pour a base, the acid salt will absorb it and again the final pH will remain the same. So the buffers are used to maintain the same pH does not matter if you add small quantities of an acid or base.
