is more basic than in imidazole.
Imidazole have two nitrogen attached in the ring at .
This compound is an aromatic compound as it have π electrons which means lone pair electrons of nitrogen atom also takes part in π
system.
Thus when a proton attacks on this compound it easily attacks at rather than .
After the attack of ion at the conjugate base thus formed is also aromatic and hence is more stable.
If the proton had attacked at the conjugate base would not be aromatic and its stability will decrease.
The reaction is shown in the image attached

Answer:
The mass of water is 36 g.
Explanation:
Mass of hydrogen = 4 g
Mass of water = ?
Solution:
First of all we will write the balance chemical equation:
2H₂ + O₂ → 2H₂O
Number of moles of hydrogen = mass / molar mass
Number of moles of hydrogen = 4 g/ 2 g/mol
Number of moles of hydrogen = 2 mol
Now we compare the moles of water with hydrogen from balance chemical equation.
H₂ : H₂O
2 : 2
Mass of water = moles × molar mass
Mass of water = 2 mol × 18 g/mol
Mass of water = 36 g
If the water oxygen is in excess than mass of water would be 36 g.
Limestone eventually erodes away, you can see it actually happening in natural caves quite often
Answer:
Explanation:
Length: Length is a measure of distance
Height:The measurement from base to top or (of a standing person) from head to foot.
Circumference:The enclosing boundary of a curved geometric figure, especially a circle
Perimeter: Length of the outline of a shape.
Diagonal:A line segment that goes from one corner to another, but is not an edge. So when we directly join any two corners (called "vertices") which are not already joined by an edge, we get a diagonal. Diagonals of Polygons.
Diameter: A straight line passing from side to side of any figure or body, through its center.
