What are the main steps to Analyse risks that you identify? To carry out a Risk Analysis, you must first identify the possible threats that you face, then estimate their likely impacts if they were to happen, and finally estimate the likelihood that these threats will materialize. What are the 4 principles of risk management? […]
How do you know if a solution is saturated or supersaturated?
How do you know if a solution is saturated or supersaturated? It’s easy to tell if a solution is unsaturated, saturated, or supersaturated by adding a very small amount of solute. If the solution is unsaturated, the solute will dissolve. If the solution is saturated, it won’t. If the solution is supersaturated, crystals will very […]
How are 15 electrons arranged in a phosphorus atom?
How are 15 electrons arranged in a phosphorus atom? When we write the configuration we’ll put all 15 electrons in orbitals around the nucleus of the Phosphorus atom. In writing the electron configuration for Phosphorus the first two electrons will go in the 1s orbital. Since 1s can only hold two electrons the next 2 […]

What level of no2 is dangerous?
What level of no2 is dangerous? According to the Occupational Safety and Health Administration (OSHA)2, the permissible exposure limit for NO2 in homes and offices should not exceed 5 ppm (9 mg/m3). However, NO2 levels as low as 0.1 ppm have been shown to cause respiratory discomfort in vulnerable populations such as asthmatics. Why is […]
Do batteries last longer in parallel or series?
Do batteries last longer in parallel or series? When batteries are hooked up In series, the voltage is increased. For example, two – 6 Volt batteries connected in series produce 12 Volts. When batteries are hooked up in parallel, the voltage remains the same, but the power (or available current) is increased. This means that […]
Can bone marrow repair itself?
Can bone marrow repair itself? It can replace diseased, nonfunctioning bone marrow with healthy functioning bone marrow. This is used for conditions such as leukemia, aplastic anemia, and sickle cell anemia. It can regenerate a new immune system that will fight existing or residual leukemia or other cancers not killed by chemotherapy or radiation. How […]
Is there an end to the universe?
Is there an end to the universe? The end result is unknown; a simple estimation would have all the matter and space-time in the universe collapse into a dimensionless singularity back into how the universe started with the Big Bang, but at these scales unknown quantum effects need to be considered (see Quantum gravity). How […]
How do you identify a star pattern?
How do you identify a star pattern? To identify the constellations, most observers use star charts, which can be found online and in astronomy books. Others use planetarium software such as Stellarium or an astronomy app. There are many such tools available that will help observers make useful star charts for their observing enjoyment. Does […]
