<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:
2.0 × 10⁴ mg
Explanation:
Step 1: Given data
Mass (m): 0.020 kg
Step 2: Convert the mass from kilograms to grams
We will use the conversion factor 1 kg = 1,000 g.
0.020 kg × (1,000 g/1 kg) = 20 g
0.020 kg is equal to 20 g.
Step 3: Convert the mass from grams to milligrams
We will use the conversion factor 1 g = 1,000 mg.
20 g × (1,000 mg/1 g) = 2.0 × 10⁴ mg
20 g is equal to 2.0 × 10⁴ mg. Then, 0.020 kg is equal to 2.0 × 10⁴ mg.

Answer:
A catalyst is a substance that speeds up the rate of a chemical reaction but is not consumed during the course of the reaction. A catalyst will appear in the steps of a reaction mechanism, but it will not appear in the overall chemical reaction (as it is not a reactant or product).
Answer:
which produces hydrogen ion in water, called acid. A substance which produces hydroxide ion in water, called base. According to Bronsted-Lowry theory, an acid is proton donor and base is proton acceptor. Actually, Arrhenius theory is limited only to the aqueous solution.
