The main difference between symptoms is that: Heartburn tends to be worse after eating and when lying down, but a heart attack can happen after a meal, too. Heartburn can be relieved by drugs that reduce acid levels in the stomach. Heartburn does […]
Why do we use thin gold foil?
Why do we use thin gold foil? For the scattering experiment, Rutherford wanted a metal sheet which could be as thin as possible. Gold is the most malleable of all known metals. It can easily be converted into very thin sheets. Hence, Rutherford selected a gold foil for his alpha-ray scattering experiment. What was most […]
What are two differences between mitosis and meiosis quizlet?
What are two differences between mitosis and meiosis quizlet? In mitosis, the result is 2 diploid cells that are identical to the parent cells. In Meiosis, the result is 4 haploid cells that are different from each other. The purpose of meiosis is creating haploid cells (gametes) that can join/fuse for sexual reproduction multicellular organisms. […]

What is the composition of H+? Hydrogen Ion, also known as H+ or hydron, belongs to the class of inorganic compounds known as other non-metal hydrides. These are inorganic compounds in which the heaviest atom bonded to a hydrogen atom is belongs to the class of ‘other non-metals’….Structure for FDB030899 (H+) Synonym Source Protons MeSH […]
Is it possible to increase the temperature of a gas without giving it heat?
Is it possible to increase the temperature of a gas without giving it heat? Yes, during adiabatic compression the temperature of a gas increases while no heat is given to it. In compression work is done on the gas i.e. , work done is negative. Hence, internal energy of the gas increases due to which […]
What is the velocity of the piston at bottom dead center?
What is the velocity of the piston at bottom dead center? As the piston reciprocates inside the cylinder, its velocity is zero at the very top (top dead center) and bottom (bottom dead center) of its stroke and quicker mid-stroke (#2). That is, its velocity varies and that change is called acceleration. What is caused […]
Is blood transparent or opaque?
Is blood transparent or opaque? In an isotonic solution the blood is opaque. In a hypo-tonic solution the blood is completely transparent. In a hyper-tonic solution the blood is virtually opaque however does allow some light through. Is Water transparent or opaque? Materials like air, water, and clear glass are called transparent. When light encounters […]
How many solar and lunar eclipses are there in 2020?
What happens if there is too much carbonic acid in the ocean?
What happens if there is too much carbonic acid in the ocean? There, carbon dioxide turns into carbonic acid. And that turns ocean water corrosive, particularly to shellfish and corals. Biologists are now coming to realize that rising acid levels in the ocean can affect many other forms of sea life as well. More CO2 […]
