How is the process of converting kiwi into plasticware evidence of a chemical reaction?.
galben [10]

Chemical reaction to biomass, like kiwi, into synthetic materials, like plastic, impact society because kiwi is biodegradable but plastic is not.

The series of chemical reactions used to change natural resources into synthetic products is termed chemical synthesis. Synthetic materials are formed when humans mix substances together for the purpose of creating new materials with desirable properties. Synthetic materials are produced by chemically changing the initial substances to create some material with different characteristics. Some of the best examples of synthetic materials are plastics and medicines. A synthetic substance may or may not be chemically identical to a naturally-occurring substance.

What is the net charge of the peptide arg-ala-phe-leu at ph 8?
adell [148]
The structure of this oligopeptide is attached:

It consists of arginine - alanine - phenylalanine and leucine

From the picture we can see that N terminus charge is +1
Also Arginine is considered as basic amino acid with charge +1
C terminus charge is -1

At pH = 8, the whose pKa are less than pH will be deprotonated and the net charge will be +1 

So the net charge of this oligopeptide is +1 at pH = 8

Can you pls tell me the net ironic equation of H₂²⁺(aq) + O₂²⁻(aq) + Mg²⁺(aq) + SO₃²⁻(aq) → Mg²⁺(aq)+SO²⁻₄(aq) + H₂O(l)
almond37 [142]

Answer:

H₂²⁺(aq) + O₂²⁻(aq) + SO₃²⁻(aq) → SO²⁻₄(aq) + H₂O(l)

Explanation:

H₂²⁺(aq) + O₂²⁻(aq) + Mg²⁺(aq) + SO₃²⁻(aq) → Mg²⁺(aq) + SO²⁻₄(aq) + H₂O(l)

A careful observation of the equation above, shows that the equation is already balanced.

To obtain the net ionic equation, we simply cancel Mg²⁺ from both side of the equation as shown below:

H₂²⁺(aq) + O₂²⁻(aq) + SO₃²⁻(aq) → SO²⁻₄(aq) + H₂O(l)
