Answer:
2Al(s) + 6HCl(aq) = 2AlCl3(aq) + 3H2(g)
Explanation:
The reaction is a displacement reaction.
The reaction does not commence immediately because the Al(aluminum) has Al2O3 (Aluminum oxide) which protect it from reacting with water.
It takes some time for the HCl (hydrochloric acid) to eat the coating, then the reaction proceed vigorously to produce hydrogen gas bubbles. Generally metals that are above hydrogen in the electrochemical series tend to displace Hydrogen from Hydrochloric acid. The more negative the electrochemical volts the more the tendency to lose electron. Metal above hydrogen have negative evolts while those below have positive evolts
New computers are faster and more efficient.
New computers have less hazardous waste.
New computers run cooler and faster.
First you need to know Avogadro's number which is 6.02 times 10^23 molecules in 1 mole of a substance. So now just divide your number by Avagadro's number to get the number of moles.
Answer:
The base pairs are what makes up an individual's genes.
Check below for further explanation.
Explanation:
The base pairs A, C, T and G are the basic molecules which makes is the DNA of individual.
The genes of an individual which determines the phenotypical expressions found in an individual such as eye colour, height, etc, are functional units found in the DNA.
Therefore, the arrangement of the base pairs determines the gene present in an individual and thus, the individual's phenotype.
