Can Methanol hydrogen bond with itself? Methanol is certainly similar to formaldehyde in some ways. It is these strong hydrogen bonds that are responsible for the relatively high boiling point of methanol; there is so much positive charge on the hydrogen of the OH group that it can essentially form a real bond with the […]

What are the sources of error in this experiment?
What are the sources of error in this experiment? You are measuring against a standard, using an instrument that can never perfectly duplicate the standard, plus you’re human, so you might introduce errors based on your technique. The three main categories of errors are systematic errors, random errors, and personal errors. What is meant by […]
What are the negative effects of the atmosphere?
What are the negative effects of the atmosphere? Acid rain, climate change and smog all damage the Earth surface. Contaminated water and gases seep into the earth, changing the composition of soils. That directly affects agriculture, changing crop cycles and the composition of the food we all eat. How do humans affect the atmosphere? Humans […]
Why does rain make me feel safe?
Why does rain make me feel safe? Studies have found that when rain sounds enters people’s brain, brain unconsciously relaxes and produces alpha waves, which are very close to the state of brain when human sleeps. Rain sound is generally between 0 and 20 kHz. It is not upsetting. On the contrary, this sound makes […]
What are the 2 numbers given for each element?
What are the 2 numbers given for each element? The number above the symbol is the atomic mass (or atomic weight). This is the total number of protons and neutrons in an atom. The number below the symbol is the atomic number and this reflects the number of protons in the nucleus of each element’s […]
Does helium go bad?
Does helium go bad? No, helium does not expire. You must close the valve tightly or helium will leak over time. Are Balloon Time tanks recyclable? What weight can helium lift? Helium atoms weigh less than the oxygen and nitrogen atoms in the air. Helium has a lifting force of about one gram per litre. […]

Does the stomach produce mucus?
Does the stomach produce mucus? The stomach has a two-layered mucus system, composed of an inner, attached mucus and an outer, unattached, loose mucus layer, both built by the MUC5AC mucin produced by the superficial epithelium. Glands in the stomach and duodenum secrete the gel-forming mucin MUC6. What would happen if there was no mucus […]
