Answer:
14.9 g Sb
Explanation:
The mass of Sb produced can be calculated using the conversion:
Molar Mass (g/mol) = mass (g) / moles
Antimony (Sb) has the molar mass 121.76 g/mol. This value is found on the periodic table. You have been given the moles produced. Therefore, you can find the mass of Sb by plugging these values into the formula and simplifying.
Molar Mass = mass / moles
121.76 g/mol = mass / 0.122 moles
14.9 = mass
Answer:
Gamma Rays
Gamma Rays-have the smallest wavelengths and the most energy of any other wave in the electromagnetic spectrum.
Explanation:
Answer:
7
Explanation:
(Note: for a strong acid and strong base titration the equivalence point is at a pH=7. This is because at this point you have equal moles of added base as acid in the original solution. Therefore at the equivalence point the solution has formed a neutral salt and the pH is 7).
Answer:Sodium ions
Explanation:
The membrane potential of most cells is negative, when sodium ions enters the cells, it can reverse the polarity and makes it positively charge.
Explanation:
Mutations on DNA create genetic variation and diversity on which natural selection acts upon. Mutation can be advantageous, disadvantageous or neutral. Those mutations that confer advantage are preserved in the population while those that are DISadvantageous are weeded out. This occurs because advantageous traits that give a particular advantage to individuals in the environment, however slightest, give them an increased chance of survival and passing their genes to subsequent generations.
An example is mutation that causes sickle cell-shaped blood cells. Individuals with sickle cell blood are less likely to contract malaria. Therefore in an environment where malaria is endemic, the population will have a higher allele frequency for sickle cell alleles that populations in non-endemic areas.
