Answer:
It can create a new plant variety, cure diseases or like the current epidemic situation, vaccines, drugs, ...
Explanation:
The oxidation number of elements becomes increasingly higher from left to right. Elements have more than one stable oxidation state as we move from left to right in the periodic table.
<h3>What does periodic table mean?</h3>
The periodic table, commonly known as the periodic table of elements, is set up so that scientists may rapidly determine an element's mass, number of electrons, electron configuration, and other distinctive chemical characteristics.
<h3>Why is the periodic table important?</h3>
All known elements are grouped together in the periodic table of elements into groups with related properties. It becomes a crucial tool for chemists, nanotechnologists, and other scientists as a result. You can forecast how chemicals will react if you learn to use and comprehend the periodic table.

Answer:
When marshmallows are toasted, a chemical change occurs. The sugar molecules in the marshmallow are being changed into carbon (1). Sugar can be changed into water molecules. ... The flame on stage - oxygen diffuses to the surface of the marshmallow from the surrounding air.
Answer:
Explanation:
pH = pKa + log [ CH₃COO⁻ ] / [CH₃COOH ]
5.36 = 4.86 + log [ CH₃COO⁻ ] / [CH₃COOH ]
log [ CH₃COO⁻ ] / [CH₃COOH ] = .5
[ CH₃COO⁻ ] / [CH₃COOH ] = 3.16
moles of CH₃COOH = .680 x .9 = .612 M
Let x mole of KOH is required
x /( .612 - x ) = 3.16
x = 1.933 - 3.16 x
x = .46488
.46488 moles of KOH will be required
volume required be V
v x 2.62 = .46488
v = .1774 L
= 177.4 mL
177.4 mL of 2.62 M KOH will be required .
The cooling of a mint is just a sensation if you were to put mints into warm water the water would remain warm because it is just a cooling sensation. I hope this helps:)
