N = m/M
= 200g/(12.01g/mol + 2(16.00g/mol))
=4.54mol
<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 .
Answer:Properties that help geologists identify a mineral in a rock are: color, hardness, luster, crystal forms, density, and cleavage. Crystal form, cleavage, and hardness are determined primarily by the crystal structure at the atomic level. Color and density are determined primarily by the chemical composition.
Answer:
b it increases from left to right of the group and it decreases down the period.
