The fermentation of C6H12O6 will produce CO2 and 1. C3H5(OH)3 2. C2H5OH 3. Ca(OH)2 4. Cr(OH)3

Answers

Answer is "2 - C₂H₅OH".

Fermentation is a process which is used to produce energy from sugars (glucose, sucrose and fructose) in the absence of oxygen.

Fermentation with the glucose releases energy by producing carbon dioxide (CO₂) and ethanol (C₂H₅OH) as its byproducts.
The reaction is 
           C₆H₁₂O₆ → 2C₂H₅OH + 2CO₂ + energy

A researcher is using a particle accelerator in an experiment studying isotopes. How can the researcher change one isotope into a different isotope of the same element?by removing valence electrons

by adding valence electrons

by adding or removing protons

by adding or removing neutrons

Answers

The researcher can change one isotope into a different isotope of the same element by adding or removing neutrons. This is because, isotopes are two or more forms of an element which contain equal number of protons and electrons but different number of neutrons. Isotopes differ in relative atomic mass but have same chemical properties.

Answer: by adding or removing neutrons

Explanation:

A neutron star that spins and emits beams of energy is called a _____.protostar
red dwarf
white dwarf
pulsar
black hole

Answers

Answer:

The correct answer is pulsar.

Explanation:

Protostar : Its a young star with contracting mass which gains mass from its parent molecular cloud. At this stage fusion process does not start.

Red dwarf:  A star having lower surface temperature , luminosity, mass and size than of the sun.

White dwarf : its an ultimate stage for an average mass star like sun . its a small dense star with size relatively equal to planet.

Pulsar :  A rotating neutron star that emits beam of radio waves and other electromagnetic radiations.

Black hole:  It is region of space time with very strong gravitational pull that even smallest particle or electromagnetic wave is incapable to escape it.
I believe its a pulsar
