False-- most of the time not enough energy is put into the system, so the compounds or whatever cant break down fully into their elements

<u>Answer:</u> The correct answer is False.

<u>Explanation:</u>

Decomposition reaction is defined as the chemical reaction in which a substance break down into two or more substances. The general chemical equation for the decomposition reaction follows:

AB\rightarrow A+B

The products of decomposition reaction can be pure elements and compounds.

For Example:

  • Decomposition of calcium carbonate to calcium oxide and carbon dioxide.

CaCO_3(s)\rightarrow CaO(s)+CO_2(g)

  • Decomposition of water into elemental hydrogen and oxygen gases.

2H_2O(l)\rightarrow 2H_2(g)+O_2(g)

Thus, the correct answer is False.

What is produced at each electrode in the electrolysis of agf(aq)?
Rzqust [24]
AgF consists of Ag+ and F- ions, which are fully dissociated in aqueous solution. When solving electrolysis problems, it is important to remember that water itself may also be a subject to electrolysis. Therefore, determining which species is oxidized and which species is reduced depends on selecting the processes that are the most energetically favorable. The most preferred reduction reaction will be  Ag+ + e- = Ag (Emf=0.7996 V) which will occur at the cathode, on the other hand, the most favorable oxidation reaction will be
2H2O = O2 +4H+ + 4e- (Emf = -1.3 V) that will occur at the anode. Thus, the product at the anode is oxygen gas and at the cathode electrode is silver metal.

During photosynthesis, plant cells use sunlight as an energy source; animal cells cannot do this. What substance do Animal cells
8090 [49]

Answer:

Chlorophyll

Explanation:

Photosynthesis is the process through which plant cells use carbon dioxide & water to create oxygen & energy rich organic compounds. They do so by converting sunlight ie light energy into chemical energy. This is possible due to presence of chlorophyll in them. Animals can't do so, as they dont have chlorophyll.
