Answer:

Thermal decomposition

Explanation:

The thermal decomposition of amino acids could be carried out at different temperatures and at fixed pressure in a reactor. The effect of temperature on products and pathway could be determined by using time as a function. The hydrothermal decomposition of amino acids takes two key paths

1. The delamination of amino acids to produce ammonia and organi acids

2. The decarboxylation to produce amines and carbonic acids.

The thermal decomposition is and effective experiment that could determine the chemical reaction rate and order of reaction, since it's working with time.

Which ionic equation describes a redox reaction? A. Ag(+) + Cl- = AgCl B. 2H(+) + CO3(2-) = CO2 + H2O C. H(+) + OH(-) = H2O D. Z
Gennadij [26K]

<u>Answer:</u> The correct option is D. Zn+Cu^{2+}\rightarrow Zn^{2+}+Cu

<u>Explanation:</u>

Redox reaction is defined as the reaction in which oxidation and reduction take place simultaneously. It is known as the reaction in which the exchange of electrons takes place.  

The oxidation reaction is defined as the reaction in which a chemical species loses electrons in a chemical reaction. It occurs when the oxidation number of a species increases.

A reduction reaction is defined as the reaction in which a chemical species gains electrons in a chemical reaction. It occurs when the oxidation number of a species decreases.

From the given ionic reactions:

Zn+Cu^{2+}\rightarrow Zn^{2+}+Cu

<u>On the reactant side: </u>

Oxidation number of Zn = 0

Oxidation number of Cu = +2

<u>On the product side: </u>

Oxidation number of Cu = 0

Oxidation number of Zn = +2

As the oxidation number of Zn is increasing from 0 to +2. Thus, it is getting oxidized. Similarly, the oxidation number of Cu is decreasing from +2 to 0. Thus, it is getting reduced. Therefore, forming a redox couple

Hence, the correct option is D. Zn+Cu^{2+}\rightarrow Zn^{2+}+Cu

The _______ of an atom are negatively charged. a. protons b. negatrons c. neutrons d. electrons
PIT_PIT [208]
Protons = +1
negatrons = -1
neutrons = 0
<span>electrons = -1
</span>
<span>negatrons are like positrons and they are subatomic particles and are not present in atoms 
</span>
so electrons are negatively charged and are present in atoms 

hope that helps
