Answer:
pyruvic acid changes to alcohol and carbon dioxide.
Explanation:
In lactic acid fermentation, pyruvic acid from glycolysis changes to lactic acid. This type of fermentation is carried out by the bacteria in yogurt, and by your own muscle cells.

An Aldotetrose is a tetrose sugar (4 Carbons) with an aldehyde functional group on the first atom.
The D- compound contains the last bottom asymmetric -OH group at the right side of the Fischer's projection. The L-compound contains the last bottom asymmetric -OH at the left side of the Fischer projection.
So the Fischer's projection of the four aldotetroses is as follow:
Nitric oxide (NO) is the catalyst used for the oxidation of SO2 to SO3 in the lead chamber process for the manufacture of sulphuric acid.

The volume of flask =10 liter
(a) 2SO2+O2⇌2SO3K=100
At an x a
end a/10 x/10 a/10
const KC=(x/10)(a/10)2(a/10)2=100
1001=10x⇒x=1/10
0.1 moles of O2 are present .
(b) 2SO2+O2⇌2SO3
At an x 2a
eq a/10 x/10 2a/10
contact
KC=(x/10)(a/10)2(102a)2⇒x/104=100
x=4/10=0.4 moles of O2.

Answer: A. Metalloids exhibit properties of both metals and nonmetals
Explanation: Metalloids are elements that has a metallic appearance such as shiny, dull amd ductile but they possess the properties of nonmetals in which they are intermediately poor conductors of heat and electricity in which they are good semiconductors.
Answer:
The process of combining the smaller nuclei to make larger one is called fusion.
Fusion occurs on the sun.
Explanation:
Fusion:
It is the process in which smaller nuclei combine to form the larger nuclei.
Fusion process also occur in the sun.
It is known as proton-proton fusion. In this proton-proton fusion, the atoms of hydrogen fused together and form helium-4. This is accomplished through several steps hydrogen atoms combine to form deuterium.
This deuterium atom fused with proton and form helium- 3.
Gamma rays are also produced in this reaction.
This helium-3 combine with another helium-3 and form helium-4 atom and two protons.
