Collisions only result in a reaction if the particles collide with a certain maximum energy called the activation energy of the reaction.
Answers
Answer: The statement collisions only result in a reaction if the particles collide with a certain maximum energy called the activation energy of the reaction, is false.
Explanation:
Activation energy is the minimum amount of energy required to initiate a chemical reaction.
So, when activation energy for a reaction is lower then molecules with lower energy can also participate in the reaction. As a result, more number of collisions will take place due to which an increase in the rate of reaction will takes place.
When activation energy for a reaction is larger then molecules with higher energy will not be able to participate in the reaction. As a result, less number of collisions will take place due to which a decrease in rate of reaction will occur.
Therefore, we can conclude that the statement collisions only result in a reaction if the particles collide with a certain maximum energy called the activation energy of the reaction, is false.

true

How many moles of gallium chlorate, Ga(ClO3)3, must react in order to produce 674 kJ of energy according to the following reaction? 2 Ga(ClO3)3 à 2 GaCl3 + 9 O2 DH = - 130.4 kJ
Answers
Answer:
10.3 mol Ga(ClO₃)₃
Explanation:
Let's consider the following balanced thermochemical equation.
2 Ga(ClO₃)₃(s) ⇒ 2 GaCl₃(s) + 9 O₂(s) ΔH = - 130.4 kJ
According to the balanced thermochemical equation, 130.4 kJ of heat are released when 2 moles of gallium chlorate react. The number of moles of gallium chlorate that must react to produce 674 kJ of energy is:
674 kJ × 2 mol Ga(ClO₃)₃/130.4 kJ = 10.3 mol Ga(ClO₃)₃
Thermochemical equations are chemically balanced equations that take into account both the energy change and the physical states of all reactants and products. Energy is a reactant in an endothermic process, whereas it is a product in an exothermic reaction. Here the moles of Ga(ClO₃)₃ is 10.3 mol.

What is the frequency of an X-ray that has a wavelength of 1.5 x 10 -9 m? The speed of electromagnetic radiation is 3.0 x 10 8 m/s. [v = λƒ]
Answers
Answer:
2.0x10¹⁷ Hz is the frequency of the X-ray
Explanation:
We can find the frequency of a wave of energy from the wavelenght and its speed using the formula:
v = λƒ
Where v is speed (For electromagnetic radiation = 3.0x10⁸m/s)
λ is the wavelength in meters = 1.5x10⁻⁹m
And f is the frequency in s⁻¹ = Hz
Replacing:
3.0x10⁸m/s = 1.5x10⁻⁹m*ƒ
3.0x10⁸m/s / 1.5x10⁻⁹m = f
f =
2.0x10¹⁷ Hz is the frequency of the X-ray

hope it helps!!!!
85 is the estimate value that is obtained from a sample of which size is likely to be closest to the actual parameter value of a population. Therefore, the correct option is option C.
What is population?A population is the entire set of people in a group, whether that group is a country or a collection of people who share a certain trait. A population is the group of people where a statistical sample has been collected in statistics. Hence, a population is any collection of people who have something in common.
A statistically substantial chunk of a population, rather than the full population, may also be referred to as a sample. For this reason, the standard deviation, meaning standard error, of a statistical study of a sample from the full population must be disclosed. Only a population-wide analysis would have zero standard deviation. 85 is the estimate value that is obtained from a sample of which size is likely to be closest to the actual parameter value of a population.
Therefore, the correct option is option C.

Answer:Reactants are starting materials and are written on the left-hand side of the equation. Products are the end-result of the reaction and are written on the right-hand side of the equation.
Explanation:
The reactants in a balanced chemical reaction are the starting material which reacts together to give the products in by the regrouping of atoms in the reactants.
What is a balanced chemical equation?The balanced chemical equation of a reaction represents the perfect stoichiometry of each reactants and products with their states of matter in brackets.
In a balanced reaction, the number of each element in the reactant side must be equal to their number in the product side. The number of each elements and groups in a reaction can be balanced by multiplying with suitable integers.
The atoms in the reactants are regrouping to form the products. Thus, the identity of the new products is entirely different form that of reactants in the reaction.

A 45.2 g sample of Silver at 101.0 ºC is dropped into 300.0 g of water at 30.6 ºC. What is the final temperature of the water?
Answers
Answer:
Final temperature of water = 31.2° C
Explanation:
Let the final temperature of water be T degrees
Concept: By energy conservation law
Heat lost by the silver = heat gained by water
Heat lost be silver Q1 = m1c1ΔT1
Q1 = 45.2/1000Kg×2.36J/KgK×(101-T)
Heat gained by water Q2 = m2c2ΔT2
Q2 = 300/1000Kg×4.186J/KgK(T-30.6)
Since, Q1=Q2
⇒ 45.2/1000Kg×2.36J/KgK×(101-T) = 300/1000Kg×4.186J/KgK(T-30.6)
Solving we get T = 31.2° C
Therefore, final temperature of water = 31.2° C
