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 […]
What happens to extra electrons in a charged object when it becomes grounded?
What happens to extra electrons in a charged object when it becomes grounded? Grounding is the process of removing the excess charge on an object by means of the transfer of electrons between it and another object of substantial size. When a charged object is grounded, the excess charge is balanced by the transfer of […]
Why is pressure not dependent on mass?
Why is pressure not dependent on mass? Static Fluid Pressure The fluid pressure at a given depth does not depend upon the total mass or total volume of the liquid. Because of the ease of visualizing a column height of a known liquid, it has become common practice to state all kinds of pressures in […]
Will the next force be equal to zero?
What are the components of centripetal force?
What are the components of centripetal force? As a bucket of water is tied to a string and spun in a circle, the tension force acting upon the bucket provides the centripetal force required for circular motion. As the moon orbits the Earth, the force of gravity acting upon the moon provides the centripetal force […]

What is difference between specificity and individuality?
What is difference between specificity and individuality? The principle of specificity means you must do specific exercises to improve specific components of physical fitness in specific body parts. The principle of individuality means that your training program must meet your goals and objectives. Everyone starts at a different place. What is an example of individuality? […]
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. […]
