Answer:
Yes
Explanation:
Chemical equation.
C₁₂H₂₂O₁₁ + 11H₂SO₄ → 12C + 11H₂SO₄ + 11H₂O
The sulfuric acid is used as a catalyst in the given reaction. Sucrose is break down into individual atoms carbon, hydrogen and oxygen.
Oxygen and hydrogen are combine to form water. The heat is released during the reaction and it is exothermic reaction. we can say that heat is given off because it is exothermic while in endothermic heat is taking by the substance.
Exothermic reaction:
The type of reactions in which energy is released are called exothermic reactions.
In this type of reaction energy needed to break the bonds are less than the energy released during the bond formation.
For example:
Chemical equation:
C + O₂ → CO₂
ΔH = -393 Kj/mol
it can be written as,
C + O₂ → CO₂ + 393 Kj/mol
1)The atom has fewer neutrons than electrons. (2) The atom has more protons than electrons. (3) The atom has the same number of neutrons and electrons.
Answer: From highest to lowest, we have Iron> water> hydrogen
Explanation: Condensation temperature is temperature at which materials transit from being a vapor to being a solid.The early solar nebula consisted of water, iron and hydrogen, and the temperature in the nebula is said to decrease with distance away from the proto-sun, with heavy elements such as iron whose distance is nearer to the protosun, will have a higher condensation temperature as compared to light elements, such as hydrogen which have lower temperature since gases are further from the sun. water vapour is heavier than hydrogen and therefore will have a higher condensation temperature than hydrogen.
