Is Granite affected by acid rain? Acid rain is slowly destroying once-resistant granite. Acid rain is created by air pollutants. The chemicals fall to earth as acid rain. Of all the building stones, granite is the least susceptible to acid rain because its composition is of feldspar and quartz, both of which resist attacks of […]
What part of Earth absorbs the most sunlight?
What part of Earth absorbs the most sunlight? the equator What absorbs the sunlight? Chlorophyll is what absorbs the sun’s energy and turns it into chemical energy. Not all the light energy from the sun is absorbed. Sunlight has many different colors in it. Chlorophyll usually absorbs red and blue light from the sun and […]
What are 2 differences between the 3 types of bonds?
What are 2 differences between the 3 types of bonds? Explanation: Covalent bonds are where two atoms share electrons. The orbitals that electrons sit in overlap between one atom and the next, which satisfies both of them and makes them stable. Ionic bonds are more like blood donations. A metal atom gives electrons to a […]
Is magnesium chloride harmful?
Is magnesium chloride harmful? Magnesium chloride supplements are considered safe if used as directed. Common side effects include stomach upset, nausea, diarrhea, and vomiting. Many of these side effects can be alleviated by taking the supplement with food. Nearly all forms of magnesium supplements have a laxative effect. What are the benefits of magnesium chloride? […]
How much force does it take to stop a moving train?
How much force does it take to stop a moving train? A light rail train requires about 600 feet to stop—the length of two football fields. Compared to this, the average freight train we mentioned above traveling at 55 miles an hour may take the length of about 18 football fields to stop. Can Spider […]
What are the two types of reflection?
What are the two types of reflection? The reflection of light can be roughly categorized into two types of reflection. Specular reflection is defined as light reflected from a smooth surface at a definite angle, whereas diffuse reflection is produced by rough surfaces that tend to reflect light in all directions (as illustrated in Figure […]
What is heating curve?
What is heating curve? A heating curve graphically represents the phase transitions that a substance undergoes as heat is added to it. The plateaus on the curve mark the phase changes. The temperature remains constant during these phase transitions. Which phase is the easiest to heat? Solid Why does the entropy increase dramatically at the […]
What do we use carbon 13 for?
What do we use carbon 13 for? Such compounds are safe because they are non-radioactive. In addition, 13C is used to quantify proteins (quantitative proteomics). One important application is in “Stable isotope labeling with amino acids in cell culture” (SILAC). C-enriched compounds are used in medical diagnostic tests such as the urea breath test. Why […]
How deep can a magnetometer go?
How deep can a magnetometer go? The corresonding sources can be from several hundred metres to 1000 metres or more, depending, as indicated before, on the “size” of the buried object or geologic horizon. Breiner, S., 1973. Applications Manual for Portable Magnetometers. How can a magnetometer be used to determine North? If the device is […]
What is a periodic table in simple words?
What is a periodic table in simple words? The periodic table is a tabular array of the chemical elements organized by atomic number, from the element with the lowest atomic number, hydrogen, to the element with the highest atomic number, oganesson. Why do they call it a periodic table? Why is the periodic table called […]
