At present, fusion reactions... Group of answer choices produce the energy in some nuclear power plants. cannot be used to produ
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.

How many moles of Ag are in 43.1 grams of Ag2O<br><br><br><br><br><br><br>​
Ivahew [28]

Answer:

0.372 mol (corr. to 3 sig. fig.)

Explanation:

no. of mole of Ag₂O

= mass of Ag₂O ÷ relative atomic mass of Ag₂O

= 43.1 ÷ ( 107.9 × 2 + 16 )

≈ 0.185936151 mol

∵ Ratio of Ag:Ag₂O = 2:1

∴ no. of mole of Ag

= no. of mole of Ag₂O × 2

≈ 0.371872303 mol

= 0.372 mol (corr. to 3 sig. fig.)
