H will definitely be positive because a bond is always more stable than no bond surely if it is a sigma bond.
For G you can't really know because you don't know how much energy is provided by the bond and if it outways the loss in disorder.


The reaction will become more spontaneous with a lower temperature because H tells you the reaction is exotherm

A blank is scientific knowledge established through direct observation and remains constant. Scientific knowledge can change whe
KIM [24]

The words that complete the blanks are hypothesis and experimentation.

<h3>What is scientific knowledge?</h3>

The process by which scientists obtain information and establish knowledge is;

Observation ---> hypothesis ------> experiments ------> Theory -------> Law.

Thus after the process of observation what we have is merely a scientific hypothesis that needs to pass through the process of rigorous experimentation before it is proven to be true.

Thus the words that complete the blanks are hypothesis and experimentation.

An analytical chemist is titrating of a solution of ammonia with a solution of . The of ammonia is . Calculate the pH of the bas
harina [27]

Answer: The question has some details missing. here is the complete question ; An analytical chemist is titrating 88.4 mL of a 0.2700 M solution of ammonia (NH3 with a 0.4300 M solution of HNO3. The pK, of ammonia is 4.74 Calculate the pH of the base solution after the chemist has added 66.3 mL of the HNO3 solution to it . Note for advanced students: you may assume the final volume equals the initial volume of the solution plus the volume of HNO3 solution

Explanation:

Given ;

  • number of moles of base = 88.4 x 0.2700 = 23.868
  • number of moles of acid = 0.4300 x 66.3 = 28.509
  • This was after the equivalence point, as such net moles of acid = 28.509 - 23.868 = 4.641mol
  • total volume of solution = 88.4 + 66.3 = 154.7mL
  • Concentration of Acid = moles/volume = 4.641/154.7 = 0.03M
  • From pH = -log[H^+] = -Log[0.03]
  • pH = 1.52

Describe how elements of different electronegativities can share electrons unequally, leading to the formation of a polar covale
Nesterboy [21]
A polar covalent bond is a covalent bond in
which the atoms have an unequal attraction for
electrons and so the sharing is unequal. ... The
atom with the greater electronegativity acquires
a partial negative charge, while the atom with
the lesser electronegativity acquires a partial
positive charge.
