Answer:
The equilibrium constant for this reaction at 55 ?C is 6.68. A pharmaceutical chemist makes up 15.0 L of a solution that is initially 0.275M in acetic acid and 3.85M in ethanol. At equilibrium, how many grams of ethyl acetate are formed?
Explanation:
In "condensed structural formula" each carbon atom and its attached hydrogen atoms are written in group in the linear form is correct about organic chemistry.
Option B
<u>Explanation</u>:
"condensed structural formula" is a method of writing or presenting organic structures in line of text. It presents all the atoms, but excludes the vertical bonds and all the horizontal single bonds. In condensed structural formula, or we can say semi-structural formula, covalent bonds are not always presented or shown. When the formula or representation is written in line with covalent bonds being shown, then it is referred to as linear formula. For example- the condensed structural formulas of ethane, propane, and ethanol is written as follows:-
Apart from these Statement, all others are false because they do not have any logic with respect to organic chemistry.
Answer:
c. AgNO₃(aq) + NH₄Cl(aq) ->AgCl(s) + NH₄NO₃(aq)
Explanation:
We have to follow the <u>solubility rules</u> to check the states of each compound.
-) All the cholride salts are soluble EXCEPT those also containing: lead, silver or mercury. 
-) All the nitrate 
and ammonium salts 
are soluble.
With this in mind 
, 
and 
would be soluble, so we have to use the <u>aqueosus state (aq).</u>
The 
then would have a <u>solid state (s)</u>.
Answer:
One triple bond and four non bonding electrons
Explanation:
In considering the lewis structure of carbon monoxide, we must remember that the molecule contains a total of ten valence electrons. Four are the valence electrons that are present on the valence shell of carbon while six are the valence electrons on oxygen. Some of these valence electrons participate in bonding in the CO molecule.
Out of the six valence electrons on oxygen, two valence electrons participate in bonding with carbon while the other four electrons remain localized on the oxygen atom as two lone pairs of electrons.
Hence there are four nonbonding electrons in the lewis structure of CO as well as one triple bond.
An object floats if it has low density or has less mass per unit volume. So, Icefloats on water because ICE is lessdenser than WATER. Most of the substances are more dense in their solid state, but water is different. This peculiarity is on account of the structure of ice.
I really hope this helped!!!! ❤
