<h2>Given reaction:
</h2><h2>C2H2 + 2H2 → C2H6
</h2><h2>This reaction represents: Combination reaction </h2>
Explanation:
When two or more substances react and form some new substance it is called as chemical reaction .
A + B --> C + D
(reactants ) (products )
Types of chemical reaction
we come across different types of reactions that occur in nature .
Out of them , combination is also one type
Combination reaction
It is a reaction ,when two or more reactants react to form single product .
i.e A+B-----AB(IN THIS ONE SINGLE PRODUCT IS FORMED )
- This reaction can be between element element , element compound or compound compound .
LIKE : H₂+Cl₂------HCL
(E) (E) (PRODUCT )
SO₂+O₂----SO₃
© (E) (PRODUCT )
CO₂+H₂O----H₂CO₃
In the above asked equation :
C₂H₂ + 2 H₂ --> C₂H₆
- The ethane is formed by combination reaction
- This reaction obeys law of conservation of mass as it is balanced .
Hi there
Formula
M1V1=M2V2
(455*6)/2500
Answer
1.092 M
Answer:
6
Explanation:
Prob already got it but it’s whatever
Answer:
1.67 M
Explanation:
The following data were obtained from the question:
Initial volume (V1) of solution = 250 mL
Initial Molarity (M1) of solution = 0.5 M
Final volume (V2) of solution = 75 mL
Final Molarity (M2) of solution =?
Thus, we can obtain the final molarity of the solution by using the following formula:
M1V1 = M2V2
0.5 × 250 = M2 × 75
125 = M2 × 75
Divide both side by 75
M2 = 125 /75
M2 = 1.67 M
Thus, the new Molarity of the solution is 1.67 M.
