What are the period and group trends in electronegativities
Leviafan [203]

Electronegativity of an element decreases as we move down a group on the periodic table and electronegativity increases while moving from left to right across a period on the periodic table.

Explanation:

  • The electronegativity increases as we move from left to right across a period because from left to right across a period, the nuclear charge is increasing Hence the attraction for the valence electrons also increases.
  • As we move down a group, the atoms of each element have an increasing number of energy levels. The distance between the nucleus and valence electron shell increases and reduces the attraction for valence electrons. Hence electronegativity decreases as we move from top to bottom down a group.

Draw the structure of the compound formed from propanoic acid and dimethylamine
jeyben [28]

 The compound form from propanoic acid and dimethylamine is 3-(dimethylamino)propanoic acid. Propanoic acid is a liquid carboxylic acid that has pungent and unpleasant smell resembling to body odor. Its chemical formula is C2H5C00H. Moreover, dimethylamine is an organic compound and a secondary amine that is colorless, flammable gas with an ammonia like odor. Its chemical formula is (CH3)2NH.

The 2D structure is attached here.

What is the hydrogen ion and hydroxide ion concentration for a pOH of 3.557? Is the solution an acid or a base?​
UkoKoshka [18]

Answer:

Hydrogen ion concentration is 2.773E-4Mole per DM3

Hydroxide ion concentration is 4.093E-11

It is an acid

Explanation:

PH(H3O)=-LogH3O

PH=3.557

H3O=antilog of -3.557

antilog of -3.557=antilog (0.443 -4)

antilog0.443 ×antilog -4=2.773E-4mole per DM3.

(H3O)(OH)=10^-14

H30=2.773×10^-14

OH= 1.00E-14/2.773E-4

=4.093E-11

it is an acid since the concentration of hydrogen ion is more than the hydroxide ion

The mass of 1.49 of H2 gas at stp
FinnZ [79.3K]

Answer:

Explanation:

I'll assume 1.49 is liters.

All gases occupy 22.4 L for each mole of gas at STP.  This makles a very useful, and important, conversion factor:

(22.4L/mole gas) for all gases at STP.

Therefore 1.49L of H2 would be:

(1.49L H2)/(22.4L/mole gas) = 0.0665 moles

The molar mass of H2 is 2, so:

(0.0665 moles)*(2g/mole) = 0.133 grams to 3 sig figs

M(Ag)=12.5 g
Nₐ=6.022*10²³ mol⁻¹

n(Ag)=m(Ag)/M(Ag)

N=n(Ag)*Nₐ

N=Nₐm(Ag)/M(Ag)

N=6.022*10²³mol⁻¹*12.5g/107.868g/mol=6.97*10²²


A. 6.97 × 10²² atoms
