You can solve this by dividing the mass by the molar mass. The molar mass of CuF2 is about 101.5 g/mol. Therefore there are 100.0/101.5 = 0.985 mol.
Answer:
The open system evaporates the solvent in the solution
Explanation:
An open system is a system in which exchange of materials and energy can occur. If a TLC set up is left open, then the set up constitutes an open system.
During TLC, the sample is dotted on the plate and inserted into a suitable solvent. The solvent moves up the plate and achieves the required separation of the mixture.
Most of these solvents used used TLC are volatile organic compounds. Therefore, if the TLC set up is left open, the solvent will evaporate leading to poor results after running the TLC experiment.
Answer: 0.45 moles of 
will be produced from 0.15 moles of propanol.
Explanation:
The balanced chemical reaction is:
is the limiting reagent as it limits the formation of product and 
is the excess reagent.
According to stoichiometry :
2 moles of produces = 6 moles of
Thus 0.15 moles of 
will produce=
of
Thus 0.45 moles of will be produced from 0.15 moles of propanol.
Answer:Muscle growth or “skeletal muscle hypertrophy,” as it's called at science parties) is the result of a complex process that adds more myosin “filaments” to each muscle fiber. This makes the “engine” of the cell bigger and stronger over time. ... This process is called muscle protein synthesis, or MPS. Skeletal muscle is composed of thread-like myofibrils and sarcomeres that form a muscle fiber and are the basic units of contraction. The 650 skeletal muscles in the human body contract when they receive signals from motor neurons, which are triggered from a part of the cell called the sarcoplasmic reticulum.
