Linear glucose forms its cyclic form by an internal nucleophilic addition reaction.
This element is Helium. This is because it has two protons and two neutrons in its nucleus. this makes it have the atomic mass of approximately four atomic mass units. It also has two electrons in the first energy level. . It is therefore a noble gas since this is the only energy level and it obeys the 2n² rule for the filling of energy levels. n in this case is 1 making the maximum number of electrons in the first energy level to be 2.
Answer: 2.186 m
Explanation:
formula for molality: (mol solute)/(kg solvent)
Na2CO3 = solute
510g Na2CO3 * ( 1 mol / 106 g) = 4.811 mol solute
ethylene glycol = solvent
2.2 * 10^3 g * ( 1 kg / 1000 g) = 2.2 kg
(4.811/2.2) = 2.186
Hubble's launch and deployment in April 1990 marked the most significant advance in astronomy since Galileo's telescope. Thanks to five servicing missions and more than 25 years of operation, our view of the universe and our place within it has never been the same.
