Metallic bonds are forces that holds atoms together in a marlin substance
Explanation:
Uranium-238 undergoes a radioactive decay series consisting of 14 separate steps before producing stable lead-206. This series consists of eight α decays and six β decays.
Answer:
0.250L of solution. 0.250 moles of solute.
Explanation:
As you can see in the image, there is a beaker with an amount of solution. 1/2L are 500mL and each line of the beaker represents 100mL. That means the volume of the solution is approximately 250mL = 0.250L
Molarity is an unit of concentration defined as the moles of solute per liter of solution. A solution that is 1.000M contains 1.000 moles of solute per liter of solution.
As the volume of the solution is 0.250L, the moles are:
0.250L * (1.000mol/L) = 0.250 moles of solute
The bacteria are chemoautotrophs. These microorganisms make use of molecules that are inorganic for energy and using carbon dioxide for carbon source. The process of obtaining energy is called chemosynthesis which uses molecules like hydrogen sulfide, ferrous iron, ammonia and the like.
