Answer:
solid to liquid i think
Explanation:
entropy is natural disorder in simple terms- liquid the atoms are less organised than in a solid to increased entropy as they move apart becoming disordered
at least this is how i understand it
Noble gases belong to group 18 of the periodic table. These elements are inert because they have their valence orbital shells as ‘full’ hence do not participate in reactions since they cannot share electrons. These elements have a pattern in their electron configuration. Their outer most orbital shells has 8 electrons (with the exception of 2 for helium).
B.
The cynobacteria were already there without the oxygen, so that rules out A, and a lot of prokaryotes were anaerobic, so that rules out C. Finally, Photosynthesis does not require oxygen. Instead, Oxygen is a waste product of it. Therefore, it cannot be D. So, we are only left with B
Hoped this helped :D
To answer this question, you need to know the aluminum acetate weight and formula. Molecular weight of aluminum acetate is 204.11g/mol, so the concentration should be: (25.20/204.11 )/(0.185l) = 0.1234 mol/0.185l= 0.6673 M<span>
</span>The aluminum acetate Al(C2H3O2)3 which mean for one aluminum acetate there will be 3 acetate ion. The concentration of acetate should be: 0.6673 M= 2M
Answer:
<h2>None</h2>
Explanation:
In the given sequence there is 9 amino acid in which 2 are positively charged amino acid and 7 are neutral amino acid at physiological pH . In each amino amino acid two oppositely charged amino and carboxyl group is present ,where amino is positively charged and proton acceptor and carboxyl is negatively charged and proton donor at physiological pH . pH below neutral cause addition of proton in amino group and makes amino acid positively charged , while pH above neutral cause addition of hydroxide ion in carboxylic group and makes amino acid negatively charged . At pH-4 , all amino acid in the given sequence become positively charge due to addition of proton in the solution ,these protons in the solution binds to amino acid sequence, hence there is no negative charged amino acid in the sequence .
