Triss [41]

Answer:

cannot be used to produce energy in reactors.  

Explanation:

Currently, there is no reactor that can allow the use of nuclear fusion, although nuclear plants use nuclear fission reactors.

Nuclear fusion happens when thousands of atoms collide with each other when they are in the midst of extreme conditions of literature and pressure. This collision causes the atoms to fuse, creating another element. The process releases amounts of light and heat, promoting a high release of energy. This whole process occurs without the release of CO2 into the atmosphere, without the release of toxic waste and without the risk of explosions, which makes nuclear plants have a strong interest in building a reactor to use this type of energy. For this reason, scientists from different countries have collaborated with each other on a project called Iter, which seeks to build a reactor and achieve the first reaction in 2025.

All the following are acid ionization reactions except
kompoz [17]

A substance that reacts with certain metals to produce salts and releases hydrogen ions into water. Acids give certain dyes a reddish tint and have a sour flavor. Some body-produced acids, such as stomach acid, can support organ function. Hydrochloric acid is a kind of acid.

What is Ionization Reaction?

A neutral atom or molecule can become electrically charged atoms by obtaining or losing a free electron, which is the definition of ionisation. Ionization takes place during a chemical reaction. An atom or molecule must either lose or gain electrons in order to ionise; the electron that is gained or lost creates an ion. An anion is a negatively charged atom or molecule that has gained an electron.

The atom or molecule that gains a free electron but loses it becomes positively charged and is known as a cation. Energy is either released or gained during ionisation.

Which subatomic particles are located in the nucleus of a ca-40 atom?
san4es73 [151]

Answer:

3) neutrons and protons

Explanation:

I just completed Grade 11 Chemistry with a 97% and I'm still under the impression that all atoms have only neutrons and protons in their nuclui.

I apologize if this is a question above my current education.

What are the molality and mole fraction of solute in a 22.3 percent by mass aqueous solution of formic acid (HCOOH)?
Vanyuwa [196]

Answer:

Mole fraction for solute = 0.1, or 10%

Molality = 6.24 mol/kg

Explanation:

22.3% by mass → In 100 g of solution, we have  22.3 g of HCOOH

Mass of solution = 100 g

Mass of solute = 22.3 g

Mass of solvent = 100 g - 22.3g = 77.7 g

Let's convert the mass to moles

22.3 g . 1mol/ 46 g = 0.485 moles

77.7 g. 1mol / 18 g = 4.32 moles

Total moles = 4.32 moles + 0.485 moles = 4.805 moles

Xm for solute = 0.485 / 4.805 = 0.100 → 10%

Molality → mol/ kg → we convert the mass of solvent to kg

77.7 g.  1 kg / 1000g = 0.0777 kg

0.485 mol / 0.0777 kg = 6.24 m
