To draw the lewis structure of the ion <span>Ch3Ch2NH3+ given, we must know the number of bonds each element in the compound. C can have four bonds, H can only have 1 bond and N can have 5 bonds. In this case, first C has 3 H bonds and 1 C bond.The second C is bonded to the other C, 2 H's, and 1 N. N capable of 5 bonds is bonded to one C and 3 H's. The lacking one bond is reflected on the positive charge of the compound. </span>
Answer: The correct answer is option (b).
Explanation:
A cycle in science is defined as process or phenomena which reoccurs again after a certain interval of a time.
In a set of chemical reactions where reactant is regenerated as a product in the end. This regenerated reactant will again establish the same set of chemical reactions in a same the fashion continuously.
Krebs cycle: it is cycle which occurs during in cellular respiration which starts from acetyl-Co-A enzyme. In the end of cycle energy is released with regeneration of acetyl-Co-A enzyme which will further continue the cycle.
Calvin cycle: It is cycle which occurs in chloroplast during the process of photosynthesis which starts from carbon-dioxide. In the end sugar molecule is released with regeneration of carbon-dioxide molecule which will further continue the cycle.
Hence, Krebs cycle and Calvin cycle both are cycles of chemical reaction in which start over continually.
Meteoroids are smaller than comets and asteroids.
YYe the answer is mechanical
Answer:
2 AsCl₃ + 3 H₂S → As₂S₃ + 6 HCl
Explanation:
When we balance a chemical equation, what we are trying to do is to achieve the same number of atoms for each element on both sides of the arrow. On the right of the arrow is where we can find the products, while the reactants are found on the left of the arrow.
We usually balance O and H atoms last.
AsCl₃ + H₂S → As₂S₃ +HCl
<u>reactants</u>
As --- 1
Cl --- 3
H --- 2
S --- 1
<u>products</u>
As --- 2
Cl --- 1
H --- 1
S --- 3
2 AsCl₃ + H₂S → As₂S₃ +HCl
<u>reactants</u>
As --- 2
Cl --- 6
H --- 2
S --- 1
<u>products</u>
As --- 2
Cl --- 1
H --- 1
S --- 3
The number of As atoms is now balanced.
2 AsCl₃ + 3 H₂S → As₂S₃ +HCl
<u>reactants</u>
As --- 2
Cl --- 6
H --- 6
S --- 3
<u>products</u>
As --- 2
Cl --- 1
H --- 1
S --- 3
The number of S atoms is now equal on both sides.
2 AsCl₃ + 3 H₂S → As₂S₃ + 6 HCl
<u>reactants</u>
As --- 2
Cl --- 6
H --- 6
S --- 3
<u>products</u>
As --- 2
Cl --- 6
H --- 6
S --- 3
The equation is now balanced.
