Answer:
Dmitri Mendeleev
Explanation:
Dmitri Mendeleev a Russian Chemist arranged elements on the periodic table according to their atomic mass. He used this arrangement to predict some of the properties of the missing element.
- Dmitri Mendeleev around 1869 described the periodic table.
- The table was based on the periodic law which states that "chemical properties of elements are a periodic function of their atomic weights".
- In the Mendeleev table, elements are arranged by atomic weights with recurring properties in a periodic manner.
The best description of bond angles around the carbon atoms of 1-butene is double bonded unsaturated carbon atoms and sp2 hybridized
<h3>What are organic compounds?</h3>
Organic compounds are those organics substances containing carbon and hydrogen only.
Some classes of organic compounds are:
So therefore, the best description of bond angles around the carbon atoms of 1-butene is double bonded unsaturated carbon atoms and sp2 hybridized

Answer:
electrons
Explanation:
A redox reaction is one in which oxidation and reduction takes place. in the sense of
oxidation being the loss of electrons and reduction the gain of electrons.
Answer:
Cu
Explanation:
We can use oxidation numbers to figure out what is happening with the electrons.
The oxidation number of Cu increases from 0 to +2 in Cu(NO₃)₂. The copper has gained two positive charges, so it has lost two electrons. It has been oxidized, so it is the reducing agent.
NO₃⁻ is wrong. The oxidation number of N decreases from +5 in NO₃⁻ to +4 in NO₂, so it has been reduced. It is the oxidizing agent.
Cu(NO₃)₂ and NO₂ are wrong. They are the products of the reaction. They cannot be either oxidizing or reducing agents in this reaction
