Why are lower-mass stars unable to ignite more massive nuclear fuels such as carbon?

Low-mass
stars have little gravitational energy, so when they contract, they don't get very hot.

Can the moon produce light through internal nuclear combustion?
No. The moon does not produce any light of its own. It only reflects light from the sun. It does not have enough mass to ignite nuclear fusion, nor is it of the right composition. Finally, nuclear fusion and combustion are two completely different processes.
Which of these develop when gravity pulls gas and dust together with enough pressure to ignite nuclear fusion?
Having some trouble seeing your list of choices from here.But stars do.
What may result when a white dwarf in a close binary system accretes matter from the companion star?
If a carbon-oxygen white dwarf accretes matter from the companion star it can reach a point where the outward pressure is not sufficient to support its plasma and it collapses until the internal pressure and heat ignite carbon fusiion in the core - producing a type 1a supernova.
What can cause a white dwarf to reignite?
The most likely way to reignite fusion in a white dwarf is for gas from a close binary companion to be pulled to it by gravity. As the gas collects the white dwarf heats up and may either ignite fusion in the hydrogen or in the carbon of the white dwarf itself.
Why is there a lower mass limit of 0.08 solar-masses for main-sequence stars?
Below about 0.08 solar masses an object will not be able to ignite nuclear fusion. There may be small amounts of deuterium fusion, but it is not sustainable. Objects between 0.08 solar masses and about 13 Jupiter masses are called brown dwarfs.
Why are lower mass stars unable to ignite more massive nuclear fuels such as carbon'?
Low-mass stars have little gravitational energy, so when they contract, they don't get very hot.
Could you ignite Neptune and create a small sun?
No. Neptune is not nearly massive enough to sustain any sort of nuclear reaction akin to the Sun. It simply does not have enough mass.
Can you ignite a fire with carbon and oxygen?
No, three things are needed the ignite a fire, carbon (fuel), oxygen and heat.
Why can't a planet be a star?
A planet does not have enough mass to ignite nuclear fusion.
What would happen if you ignite a nuclear bomb in a volcano?
You get a rather large explosion.
How do hydrocarbons ignite?
Hydrocarbons react with oxygen; the products are water and carbon dioxide.
Why are thermonuclear bombs are more disastrous than nuclear bombs?
Nuclear bombs use nuclear fission of some heavy element, usually uranium or plutonium. Thermonuclear bombs use the detonation of a fission bomb to ignite the fusion of hydrogen. Such weapons are more powerful than ordinary nuclear weapons because nuclear fusion releases more energy than nuclear fission, and because the process of fusion itself can be used to ignite more fission.
What does protosun mean?
A protosun is a sun (star) that is still forming. It takes millions of years of solar winds and gravitational forces to gather and compress massive clouds of hydrogen to the point where it's gravity is powerful enough to cause nuclear fusion at it's core and "ignite" a new star.
Could a planet become a star?
To ignite nuclear fusion, a certain temperature is required; and this, in turn, requires a certain mass. A large planet (or more precisely, a massive planet) could become a star if it acquires additional mass. Note that there is an intermediate stage, the brown dwarf - which is basically an object that is massive enough for the fusion of deuterium (hydrogen-2), but not massive enough to fuse regular hydrogen (hydrogen-1). Deuterium is much rarer than the regular hydrogen.
Stars are born when gravity pulls gas and dust together with enough pressure to ignite nuclear fusion true or false?
True.
Is short carbon chains of hydrocarbon easier to flow or long?
A hydrocarbon composed of short carbon chains will ignite more easily, just think how flammable petrol is!
Does carbon dioxide react same like hydrogen to a fire?
No. Hydrogen will easily ignite if it comes in contact if fire. Carbon dioxide is not flammable at all and can even be used to put out a fire.
