Nuclear fusion of hydrogen into helium occurs in the

Chemistry

andrezito [222]3 years ago

There are types of nuclear reaction: nuclear fusion and nuclear fission. The difference is that fusion is a combination of two elements while fission is the breaking up of the subatomic particles of an element creating a new element. The limiting element to this is Iron. Iron-26 is the most stable element. As a result, elements lighter than Fe-26 are generally fusible. This includes hydrogen and helium.

This reaction is common in the stars, most especially the Sun. The energy of the Sun comes from its abundant hydrogen composition which becomes fusible into Helium. This occurs at a temperature of 14 million Kelvin. The nuclear reaction is a not a one-way step process as shown in the picture.

Which element does this Bohr model represent? (look at a periodic table if needed)
Serjik [45]
Circulating round the nucleus are the electrons in various orbits of different energy levels. Electrons are negatively charged and represented by the symbol 'e'. In the given image the number of protons are -6. Hence the element in question is Carbon as Carbon has the atomic number 6.

What is the mole, and why is it useful in chemistry?
Snowcat [4.5K]

Answer:The mole is important because it allows chemists to work with the subatomic world with macro world units and amounts. Atoms, molecules and formula units are very small and very difficult to work with usually. However, the mole allows a chemist to work with amounts large enough to use.

Sucrose will be the most effective. Hence, option D is correct.

<h3>What is sucrose?</h3>

Sucrose is simply the chemical name for sugar, the simple carbohydrate we know and love that is produced naturally in all plants, including fruits, vegetables and even nuts.

When salt or sugar (a solute) is combined with water or ice (a solvent) and is evenly distributed, the freezing point is lowered.

(C_{12}H_{22}O_{11} → C_{12}H_{22}O_{11})

Hence, sucrose will be the most effective.
