How do you sort bonds by polarity

Chemistry

zzz [600]3 years ago

Your question isn't quite clear, but if you're wondering if a chemical is polar or non-polar, you simply draw a VSEPR sketch and draw arrows where the bonds are. Only draw arrows between atoms, NOT between an atom and a lone pair of electrons. The arrow should point to the most electronegative atom (you should be given an electronegativity scale). Afterwards, you add up the arrows as vectors, and look at the sum of the vectors. If the sum is zero (CH4 is a good example), the chemical is non-polar. If the sum is a vector, the chemical is polar (H2O, or water, is polar).

1. Provide a definition of an Arrhenius acid and an Arrhenius base. What has science determined to be the limitations of these d
lara [203]

Answer:

See Explanation ( = same answer for earlier question)

Explanation:

The Arrhenius acid-base theory defines an acid as a compound which when added into water increases the hydronium ion (H₃O⁺) concentration and the base as a compound which when added into water increases the hydroxide (OH⁻) ion concentration. As such, an acid-base reaction is limited to proton transfer to only OH⁻ ions forming water. Such would imply that all acid-base reactions produce water only in addition to a salt. This is not always the case as conjugate base anions for many substances can receive proton transfer.

Example: The reaction HOAc + NaCN => HCN + OAc-  will occur in aqueous media because the proton (H⁺) on acetic acid (HOAc) will transfer to the cyanate ion forming hydrocyanic acid (HCN). Such occurs because the CN⁻ ion is a stronger conjugate base than the acetate ion (OAc⁻) and forms the more stable weak acid.  Such is the basis of the Bronsted-Lowry Acid-Base system and states that an acid (proton donor) will transfer its ionizable hydrogen to a conjugate base (proton acceptor) if the transfer forms a weaker acid.

A zinc block with a mass of 230 g is given 1320 J of energy. What is the change in
Mariana [72]

Answer:

14.7°C

Explanation:

Q = m·ΔT·c

ΔT = \frac{Q}{m*c}

ΔT =\frac{1320 J}{230 g* 0.39 J/gC}

     = 1320 J / ((230 g) * (.39 J/g°C)

ΔT = 14.7 °C

If the heat capacity of a ceramic cup is 0.820 j°c-1, how much heat is required to raise the temperature of the cup from 25.0°c
Aleksandr [31]
The  heat  required  to raise   the  temperature  of  the  cup  from  25 c   to  50  c  is  calculated  as  follows
Q (heat)  =   c   x  delta  T
c =  specific  heat  capacity  =  0.  820   j/c
  delta T  =  change   in temperature  (  50 c-  25  c  =  25c

=  0.820 j /c  x  25 c  =  20.5  j
