b. transition state
c. rate limiter
d. collision group
Answers
Answer:
Another name for the activated complex is Transition State.
Explanation:
According to Collision Theory for a chemical reaction to occur the reactants must collide with proper orientation and required energy. In this way the old bonds are broken and new bonds are formed. The mid point of highest energy at which both bond formation and breakage is taking place is called activation complex, a complex in between reactant and product.
The energy of this complex is the minimum amount of energy required for a particular reactants to convert into products and is called as Activation Energy.
This activation complex is also termed as Transition State because according to Transition State Theory at transition state the existing bonds tend to increase in length and become weaken while, the new forming bonds tend to decrease in length and start becoming stronger. Hence, the activated complex is in transition between reactants and products.

3. C₃H₆ClO
- Molecular formulas tell you how many atoms of each element are in a compound, while
- Empirical formulas tell you the simplest or most reduced ratio of elements in a compound.
Given: Molecular formula=C₆H₁₂Cl₂O₂
So, the simplest or most reduced ratio for this formula is C₃H₆ClO which can be deduced by dividing the molecular formula by 2 in order to get its empirical formula.

Answer:
Explanation:
Molecular formula is the chemical formula which depicts the actual number of atoms of each element present in the compound.
Empirical formula is the simplest chemical formula which depicts the whole number of atoms of each element present in the compound.
Thus the compound with molecular formula will have simplest ratio of atoms as 3:6:1:1 and thus empirical formula will be

Kw = [ H₃O⁺] [ OH⁻]
1 x 10⁻¹⁴ = [ H₃O⁺] * 4 x 10⁻³
[H₃O⁺] = 1 x 10⁻¹⁴ / 4 x 10⁻³
[H₃O⁺] = 2.5 x 10⁻¹² M

Answers
Answer:
A. Some of the mass is converted to energy.
B.The products can weigh less than the reactants.
Explanation:
Nuclear reaction: A reaction in which a nuclei splits into two or more smaller nuclei of mass less than the reactants ,or two or more nuclei combined together to form heavy nuclei of mass less than the reactants and huge amount of energy released.
Nuclear reactions are of two types
1. Nuclear fission
2.Nuclear fusion
1. Nuclear fusion: A reaction in which two or more lighter nuclei combined together to form heavy nuclei of mass slightly less than the total mass of reactants and a large amount of energy released. Because the difference in mass of reactants and products change into energy .
2.Nuclear fission: A reaction in which a heavy nuclei splits into two or more lighter nuclei of total mass slightly less than the mass of reactant. Because the difference in mass of product and reactant change into energy therefore, a huge amount of energy released during this reaction.
Therefore, Option A and B are correct.
Answer : A. Some of the mass is converted to energy.
B.The products can weigh less than the reactants.
