CO2+H2O+energy represents the reactants
Answer:
Mass
Explanation:
Physical properties of substance are classified as Intensive property and Extensive property.
Intensive Property:
A physical property whose value is independent of the mass of a substance for which it is measured.
Examples:
i) Melting / Boiling Points
ii) Temperature
iii) Color
iv) Density
v) Pressure
Extensive Property:
A physical property whose value is dependent on the mass of a substance for which it is measured.
Examples:
i) Amount of Substance
ii) Mass
iii) Volume
iv) Enthalpy
v) Entropy
Orbital hybridization (or hybridization) is the concept of mixing atomic orbitals to form new hybrid orbitals (with different energies, shapes, etc., than the component atomic orbitals) suitable for the pairing of electrons to form chemical bonds in valence bond theory.
<h3>What types of hybrid orbitals are?</h3>
The five basic shapes of hybridization are linear, trigonal planar, tetrahedral, trigonal bipyramidal, and octahedral. The geometry of the orbital arrangement: Linear: Two electron groups are involved resulting in sp hybridization, the angle between the orbitals is 180°.
<h3>Why are hybrid orbitals formed?</h3>
Hybridization occurs when an atom bonds using electrons from both the s and p orbitals, creating an imbalance in the energy levels of the electrons. To equalize these energy levels, the s and p orbitals involved are combined to create hybrid orbitals.

answer:
atomic number
the same chemical element is characterized by the number of protons in the nucleus that determines the total positive charge.
Answer: Option (c) is the correct answer.
Explanation:
Entropy is defined as the degree of randomness. This means that more is the number of collisions taking place between atoms of a substance more will be the randomness.
Therefore, more will be the entropy of substance. We cannot measure the entropy but we can measure the change in entropy of a substance.
A thermometer is a glass tube that contains a liquid column generally mercury, and it is usually used to measure the temperature of human body.
A calorimeter is a device or apparatus that is used in a chemical reaction to measure the amount of heat involved.
Therefore, we can conclude that the student can't measure entropy directly, only an entropy change.
