Answer:

The correct answer is C.  The breaking of bonds.

Explanation:

it is very much important to note that formation of bonds requires energy by the same way breakage of bond releases energy.

      The energy that is released by bond breakage utilized to do work or is converted to another form of energy.

   For example ATP contain 2 phosphoanhydride bonds.Breakage of these phosphoanhydride bonds releases potential energy called free energy which is used by the body cells to exhibit their biological functions.

A very specific procedure scientists follow when conducting experiments is known as the
PtichkaEL [24]

Answer:

Scientific Method.

Explanation:

A scientific method is basically a method or a process when you conduct an experiment. Normally, the process goes like this:

1. You make like a question or something that you want to investigate, it's like the aim of the experiment.

2. You make an experiment and a hypothesis. A hypothesis is basically a guess on how the results of the experiment would turn out. You don't have to be correct for the hypothesis since there is no right or wrong answer.

3. Conduct the experiment. I don't think this needs a detailed explanation since experiments vary from one another.

4. Collect results. The data you collect come in different ways based on your experiment, but it is crucial you get data so that you can answer your question in 1.

5. Make inferences. You can't directly get a conclusion or answer from the results, so inferences are needed.

6. Craft a conclusion or answer. This is the final step when conducting an experiment and the part where you have the answer you needed when you conducted the experiment :)

Arrange the metals used in this experiment (including H2 and Ag) in order of decreasing reactivity (most reactive metal first).
jarptica [38.1K]

Answer:

Na, Ca, Mg, All, Zn, Fe, Sn, Pb, H2, Cu, Ag

Explanation:

This is how metals are arranged in the electrochemical series.

Use the following to remember the order:

King Nathan Can Manage All Zone Freely Since Probably He Can Handle All Ages

Each word represent the order

K, Na, Ca, Mg, All, Zn, Fe, Sn, Pb, H2, Cu, Hg, Ag, Au

Suppose the decomposition of dinitrogen monoxide proceeds by the following mechanism:
photoshop1234 [79]

Answer:

Part A: 2N₂O(g) ⇄ 2N₂(g) + O₂(g)

Part B: -r = K*[N₂O]²

Part C: K= k1*k2

Explanation:

Part A

To do the balance chemical question for the overall chemical reaction, we must sum the reaction of the steps, eliminating the intermediaries, which are the compounds that have the same amount both at reactants and products (bolded).

N₂O(g) ⇄ N₂(g) + O(g)

N₂O(g) + O(g) ⇄ N₂(g) + O₂(g)

---------------------------------------------

2N₂O(g) + O(g) ⇄ 2N₂(g) + O(g) + O₂(g)

2N₂O(g) ⇄ 2N₂(g) + O₂(g)

Part B

The velocity of the reaction (r) can be calculated based on the reactants or based on the products. Let's do it based on the disappearing of the reactant. Because it is disappearing, the variation at its concentration must be negative, so the rate will be negative.

Let's suppose its an elementary reaction, so, the concentration of the reactant must be elevated by its coefficient. And let's call the overall rate constant as K:

-r = K*[N₂O]²

Part C

Because the steps were summed, and the reactions were not multiplied by a constant or inverted, the constant K is just the multiplication of the constants of the steps:

K= k1*k2
