For a laboratory investigation some students put a strip of shiny metal into a beaker of blue solution and then stored the beake

r on a shelf
overnight. The next morning, the students recorded observations about the metal and the solution in the box below.
Students' Observations
Exhibit
. The solution is lighter in color,
The volume of solution is the same.
• The metal strip is shiny above the surface of the solution
• The metal strip is not shiny below the surface of the solution.
• The metal strip below the surface of the solution has a dark
coat of flaky material
• When the metal strip is touched, the flaky material falls off.
Based on their observations, can the students correctly conclude that a chemical reaction occurred?
A. No, because the metal strip was still visible
B. Yes, because a new material of a different color formed on part of the metal strip
c. No, because the solution stayed blue
ble solution stayed the same

PLZ ANSWER QUICKLY! The electronegativity values of carbon, hydrogen, and nitrogen are compared in the table. Comparison of Elec
andriy [413]

Answer:

c. CH4 < NH3 because the NH bond is more polar than the CH bond.

Explanation:

Actually, the electronegativity difference between carbon and hydrogen is just about 0.4. This meager difference in electronegativity corresponds to a nonpolar bond between the two atoms.

However, the electronegativity difference between nitrogen and hydrogen is about 0.9. This larger electronegativity difference corresponds to the existence of a polar covalent bond between the two atoms.

Hence the N-H bond is significantly polar unlike the C-H bond. This implies that CH4 molecules are only held together by weak dispersion forces while NH3 molecules are held together by stronger dipole-dipole interactions and hydrogen bonds.

What is the ph of a 0.001 62 m naoh solution?
marin [14]
The answer 
first of all, we should know that NaOH is a strong base. For such a product, the conentration of the OH -  is equivalent to the concentration of the NaOH itself.
that means:
[ OH -] = [ NaOH] =<span>0.001 62 
and for a strong basis, pH can be calculated as pH = 14 + log </span>[ OH -] 
first we compute log [ OH -] :
log [ OH -] = log (0.001 62)= -2.79

finally pH = 14 -2.79 = 11.20

N the ionic compound aluminum selenide, each atom of aluminum (gains or loses)
Volgvan

Answer:

loses, gains

Explanation:

In the ionic compound aluminum selenide, each atom of aluminum will lose electrons while each atom of selenium will gain the electrons.

An ionic compound is an interatomic bond formed between a metal and non-metal. The metal is less electronegative compared to the non-metal. In this case, the metal will lose electrons to become positively charged whereas the non-metal, selenium will gain the electron to become negatively charged.

The electrostatic attraction between these oppositely charged ions leads to the formation of the ionic bond.
