What is the purpose of thin layer chromatography? TLC is a chromatography technique used to separate non-volatile mixtures. Thin-layer chromatography can be used to monitor the progress of a reaction, identify compounds present in a given mixture, and determine the purity of a substance. What are the two major uses of thin layer chromatography? The […]
What are two examples of biogeochemical cycles?
What are two examples of biogeochemical cycles? Ecological systems (ecosystems) have many biogeochemical cycles operating as a part of the system, for example, the water cycle, the carbon cycle, the nitrogen cycle, etc. All chemical elements occurring in organisms are part of biogeochemical cycles. Is photosynthesis a biogeochemical cycle? This type of cycle of atoms […]
Is tidal energy affected by the sun?
How is density directly proportional to volume?
How is density directly proportional to volume? Density and Volume are inversely proportional to each other. Mass and volume are not the same. When density increases, volume decreases. When volume increases, density decreases. What do density mass and volume have in common? An object’s density is the ratio of mass to volume of an object. […]
How do red blood cells and white blood cells work together?
How do red blood cells and white blood cells work together? Red blood cells carry oxygen to all parts of the body. White blood cells help fight infection. Platelets are tiny cells that have a big job in stopping bleeding. Proteins in the blood called clotting factors work to form a clot. What causes white […]

How do you increase the amplitude of a sound wave?
How do you increase the amplitude of a sound wave? In theory, a sound wave can have any amplitude, and we can boost a wave by multiplying its samples with any arbitrarily large number. What is relation between frequency and voltage? As the voltage increases so does the power out of the area and frequency […]
What Hz is harmful?
What Hz is harmful? The most dangerous frequency is at the median alpha-rhythm frequencies of the brain, 7 hz. This is also the resonant frequency of the body’s organs. What frequency can kill humans? 7 hz What is the death frequency? As of 2020, the CIA estimates the U.S. crude death rate will be 8.3 […]
Is n3 Isoelectronic?
Is n3 Isoelectronic? Atoms and ions that have the same electron configuration are said to be isoelectronic. Examples of isoelectronic species are N3â, O2â, Fâ, Ne, Na+, Mg2+, and Al3+ (1s22s22p6). Is Ca2+ Isoelectronic with AR? For atoms/ions: For example, the K+ ion is isoelectronic with argon. Therefore, K+ and Ar are said to be […]
