Answer: It is caused by the tendency of some atoms in molecules to attract electrons more than their accompanying atom.
Answer:
The answer to your question is remplacement double
Explanation:
Data
Lead (II) nitrate = Pb(NO₃)₂
Potassium iodide = KI
Process
1.- Write the balanced chemical reaction
Pb(NO₃)₂ + 2KI ⇒ PbI₂ + 2KNO₃
2.- Conclusion
This is a remplacement double reaction because there are two reactants that interchange cations and the products are a combination of the reactants.
There’s no pic for me to awnser your question
Answer: There is no question, but we can calculate a couple of items:
Density of sea water sample = (52.987g-44.317g)/8.5ml
Inorganic content of sample (mostly salts) = (44.599g-44.317g)/(52.987g-44.317g) x 100% = percent inorganics in water sample
Explanation:
Conjugate base of Propanoic acid (
is propanoate where -COOH group gets converted to -CO
. The structure of conjugate base of Propanoic acid is shown in the diagram.
The
above which 90% of the compound will be in this conjugate base form can be determined using Henderson's equation as propanoic acid is weak acid and it can form buffer solution on reaction with strong base.
=
+ log
=4.9+log
=5.85
As 90% conjugate base is present, so propanoic acid present 10%.
