Answer: (B) The reverse reaction will proceed to establish equilibrium.
Explanation:
Any change in the equilibrium is studied on the basis of Le-Chatelier's principle.
This principle states that if there is any change in the variables of the reaction, the equilibrium will shift in the direction to minimize the effect.
For the given equation:
Given : when 
is added to the system
If the concentration of that is the product is increased, so according to the Le-Chatlier's principle, the equilibrium will shift in the direction where decrease of concentration of takes place. Therefore, the equilibrium will shift in the left or backward direction.
Thus the reaction will shift towards reactants to reestablish equilibrium and thus partial pressure of and 
decreases and the partial pressure of 
increases.
Answer:
Carboxylic acids react with diazomethane to produce methyl esters.
Explanation:
Diazomethane has a high reactivity and is used to produce methyl esters with carboxylic acid in a immediately reaction, carried out at room temperature in the absence of catalysts.
As we can see in the image below
- In the First Step, occurs an acid-base reaction to obtain the "carboxylate" ion.
- Second Step: The Carboxylate attacks the protonated diazomethane by a SN2 reaction to<u> finally get the Methyl Ester.</u>
The subproduct is Nitrogen; knowing this, we must be careful with the production of this gas, and do the process in a vented place
(Question 1 points 3).
Food fuel is the fuel in which we use farmland or crops for bio-fuels production to the detriment of the food supply. whereas, mechanical fuel is a material used to produce energy when it is burned. Petroleum products (gasoline, kerosene, and bunker B) are the best being used as a mechanical fuel worldwide.
(Question 2 points 3).
This is because they are lightweight, spread easily, less volatile and are relatively persistent in the environment.
C) 5 protons, 5 electrons, and 6 neutrons
Answer:
the density of metal is 7.33 g/cm³.
Explanation:
Density:
Density is equal to the mass of substance divided by its volume.
Units:
SI unit of density is Kg/m3.
Other units are given below,
g/cm3, g/mL , kg/L
Formula:
D=m/v
D= density
m=mass
V=volume
Given data:
Volume of bar metal = 4.5 cm³
Mass of bar metal = 33 g
Density = ?
Solution:
d = m/v
d = 33 g/ 4.5 cm³
d = 7.33 g/cm³
