How do you calculate the mass of a mole? First, you can calculate the molar mass of FeCl2 by adding the molar masses of Fe (55.845 g/mol) and 2 atoms of Cl (2 times (35.446 g/mol). This gives a molar mass of 126.737 g/mol. Since each mole is 126.737 grams, you multiply 3.5 mols by […]
Can a RTG power a house?
What activities improve power?
What activities improve power? The medicine ball throw is one exercise that can help you build power. The vital aspect of improving power is moving with speed. For some individuals, rising up quickly from a chair or from the bottom of a body-weight squat might suffice as a start. Other great options are jump squats […]
Can hypothesis be proven?
Can hypothesis be proven? Upon analysis of the results, a hypothesis can be rejected or modified, but it can never be proven to be correct 100 percent of the time. For example, relativity has been tested many times, so it is generally accepted as true, but there could be an instance, which has not been […]
Why do action potentials travel faster in myelinated axons?
Why do action potentials travel faster in myelinated axons? Unlike unmyelinated axons, myelinated axons are surrounded by an insulatory myelin sheath produced by Schwann cells. This results in the action potential ‘jumping’ along the axon in a process known as saltatory conduction, and thus propagating much more quickly than along an unmyelinated axon. Which nerves […]
What is needed to stop a moving object?
What is needed to stop a moving object? The force stopping the object’s motion might be an obvious one – the ground! Friction is a force that slows or stops motion. Friction is the resistance to motion created by two objects rubbing against each other (the sled and the snow, for instance). Even air causes […]
How long can you stay undetectable?
How long can you stay undetectable? A person’s viral load is considered “durably undetectable” when all viral load test results are undetectable for at least six months after their first undetectable test result. This means that most people will need to be on treatment for 7 to 12 months to have a durably undetectable viral […]
What makes water drinkable?
What makes water drinkable? Filtration – The clear water on top passes through filters composed of sand, gravel and charcoal to remove dissolved particles such as dust, parasites, bacteria, viruses and chemicals. Disinfection – Chlorine or chloramine is added to kill parasites, bacteria, viruses and germs. How do you sanitize water? Boil water, if you […]
What is a real life example of a single replacement reaction?
What is a real life example of a single replacement reaction? An example of a single replacement reaction occurs when potassium (K) reacts with water (H2O). A colorless solid compound named potassium hydroxide (KOH) forms, and hydrogen gas (H2) is set free. The equation for the reaction is: 2K + 2H2O → 2KOH + H. […]
