Solids' particles move a lot faster and closer together. Liquids' are more spread apart and move slower. So there is more energy in the solid
Answer:
Mass = 2.7 g
Explanation:
Given data:
Number of moles of C₅H₁₂ = 0.9249 mol
Mass of water = ?
Solution:
Chemical equation:
C₅H₁₂ + 8O₂ → 5CO₂ + 6H₂O
Now we will compare the moles of water with pentane.
C₅H₁₂ : H₂O
1 : 6
0.9249 : 1/6×0.9249= 0.15 mol
Mass of water:
Mass = number of moles × molar mass
Mass = 0.15 mol × 18 g/mol
Mass = 2.7 g
<u><em>Answer:</em></u>
Correct option is D.
It accelerates the reaction rates of a mixture.
<u><em>Explanation:</em></u>
It is used to speed up a reaction by lowering the activation energy.Catalysis is the backbone of many industrial processes, which use chemical reactions to turn raw materials into useful products.
<u><em>Types</em></u>
There are two types of catalyst (1) Homogeneous (2) Heterogeneous
In a heterogeneous reaction, the catalyst is in a different phase from the reactants. In a homogeneous reaction, the catalyst is in the same phase as the reactants.
The answer to the question is a
