Why is Avogadro so rich?
A: By e-mole! Q: Why is Avogadro so rich? ... A: She's his favorite super-mole-dle (and she has a mole).
Why do moles come out of the ground?
Moles are sometimes seen above ground. They come to the surface to collect nesting material and to look for food when the soil is dry. ... Moles emerge mainly at night but they are still vulnerable to predators; some mammals find them distasteful but many are eaten by tawny and barn owls.
What do you call a 10th grader who is taking chemistry?
Sophomole: Anyone in the 10th grade who is taking chemistry.
Why is the mole so important?
The mole is important because it allows chemists to work with the subatomic world with macro world units and amounts. Atoms, molecules and formula units are very small and very difficult to work with usually. ... A mole of something represents 6.022x1023 items. Whether it be atom, molecule or formula unit.
What experiment did Avogadro?
Amedeo Avogadro is best known for his hypothesis that equal volumes of different gases contain an equal number of molecules, provided they are at the same temperature and pressure. ... Avogadro was also the first scientist to realize that elements could exist in the form of molecules rather than as individual atoms.
When did Mole Day start?
Mole Day originated in an article in The Science Teacher in the early 1980s. Inspired by this article, Maurice Oehler, a high school chemistry teacher from Prairie du Chien, Wisconsin, founded the National Mole Day Foundation (NMDF) on May 15, 1991.
Why do I keep finding dead moles in my yard?
Dead moles in your yard may indicate the presence of a population of moles suffering from a disease. Moles suffer from a variety of parasitic diseases and other illnesses that may spread quickly through mole populations, killing several animals. ... Such diseases may spread to pets.
Are moles blind?
Moles are often thought to be blind when in fact they can see; they are, though, colorblind and have poor vision only adapted to recognize light. To find food and to navigate the dark underground, moles rely on their keen sense of smell and touch. ... Moles are small, burrowing mammals who live underground.
Are moles bad?
Moles are usually harmless. They may contain hairs or become raised or wrinkled. Talk to your doctor about any change in the color or size of a mole or if itching, pain, bleeding or inflammation develops.
What age is Grade 0 in South Africa?
For grade 0 (otherwise known as grade R – the reception year), the age is four turning five by 30 June in the year of admission. If parents feel their children are not yet ready for school, they are allowed to admit them at an older age – five turning six for grade 0, and six turning seven for grade 1.
Is high school biology hard?
Biology can be tough in high school for many students. It's a class with a huge amount of content. With exams that aren't always the most straightforward or simple. You'll have to prepare well and work hard to do well in biology in high school.
Why is a mole 6.022 x10 23?
The mole (abbreviated mol) is the SI measure of quantity of a “chemical entity,” such as atoms, electrons, or protons. It is defined as the amount of a substance that contains as many particles as there are atoms in 12 grams of pure carbon-12. So, 1 mol contains 6.022×1023 elementary entities of the substance.
What do you think is the importance of mole concept in our daily lives?
The mole is a unit used to talk about atoms. It is similar to other units we use everyday. For example, you might walk into the local sweet shop and order a dozen laddoos . In doing so, you know that you will get 12 of these laddoos and the owner knows to give you 12.
Why do we use moles instead of mass?
That is an extremely common question when first using stoichiometry. The answer is that you are converting based on number, not on mass. ... Big, because atoms and molecules are way too small to count, so we mass large numbers of them instead, and use molar mass to convert to the NUMBER of moles of them.
