Hey there!:
Molar mass FeF3 = 112.84 g/mol
Number of moles = mass of solute / molar mass
Number of moles = 24.0 / 112.84
Number of moles = 0.212 moles of FeF3
Hope that helps!
I think it’s ten because it’s becoming darket
Atoms will combine with each in order to become more chemically stable by sharing electron and Compounds are formed between two atoms that have chemical bond that links them together.
In order for molecules and crystals to form, atoms or ions must maintain a long-lasting attraction to one another. Ionic and covalent bonds are formed by the sharing of electrons, while ionic bonds are formed by the electrostatic attraction between two oppositely charged ions. There are "strong bonds" or "primary bonds" like covalent, ionic, and metallic bonds as well as "weak bonds" or "secondary bonds" like dipole-dipole interactions, the London dispersion force, and hydrogen bonding. The strength of chemical bonds varies greatly. By sharing or transferring electrons between the involved atoms, strong chemical bonds are created.
Since opposing electric charges attract, the positively charged protons inside a nucleus and the negatively charged electrons that surround it are drawn to one another. Placing an electron between them

The answer is d. natural gas. All the other choices are alternative sources of energy, and do not produce or emit any greenhouse gas such as carbon dioxide (CO2). Natural gas, on the other hand, is an organic substance containing a significant amount of carbon, that when burned for fuel, results in the emission of CO2.
