Chemistry
1 answer:
Svetradugi [14.3K]2 years ago
7 0

Answer:

activation energy, in chemistry, the minimum amount of energy that is required to activate atoms or molecules to a condition in which they can undergo chemical transformation or physical transport. In transition-state theory, the activation energy is the difference in energy content between atoms or molecules in an activated or transition-state configuration and the corresponding atoms and molecules in their initial configuration. The activation energy is usually represented by the symbol Ea in mathematical expressions for such quantities as the reaction rate constant, k = Aexp(−Ea/RT), and the diffusion coefficient, D = Doexp(−Ea/RT).

The reaction A( g ) ⇌ 2 B( g ) A(g) ⇌ 2 B(g) has an equilibrium constant of K = 0.010 K = 0.010. What is the equilibrium constan
Over [174]

Answer:

K = 10

Explanation:

Using Hess's law, it is possible to obtain the equilibrium constant, K, of a reaction using K of similar reactions. For example:

<em> If A ⇄ B K = X</em>

B ⇄ A K = 1/X

2A ⇄ 2B K = X².

Thus, if A(g) ⇄ 2B(g) K = 0.010

2B(g) ⇄ A(g) K = 1 / 0.010; K = 100

B(g) ⇄ A(g) K = √100 = 10

<h3>K = 10</h3>

Which phrase describes conduction?
Akimi4 [234]

Answer:

Transfer of heat between two objects that are touching.

Explanation:

Conduction is the process by which heat is transferred from one object to another object that is touching and has different temperatures.

Eg: We can use a hot water pack to warm our back. Or While cooking we can feel the conduction process when heat process from the bottom of the pan to the top of the pan

The balanced reaction between aqueous nitric acid and aqueous strontium hydroxide is _________
umka2103 [35]

Answer:

2HNO_3(aq)+Sr(OH)_2(aq)\rightarrow Sr(NO_3)_2(aq)+2H_2O(l)

Explanation:

Hello,

In this case, since nitric acid is HNO₃ and strontium hydroxide is Sr(OH)₂ we can represent the balanced chemical reaction by equaling the atoms of strontium, nitrogen, oxygen and hydrogen at both reactants and products as shown below:

2HNO_3(aq)+Sr(OH)_2(aq)\rightarrow Sr(NO_3)_2(aq)+2H_2O(l)

Best regards.
