Why are hotspots a unique type of volcano? A hot spot is a region deep within the Earth’s mantle from which heat rises through the process of convection. Hot spot volcanism is unique because it does not occur at the boundaries of Earth’s tectonic plates, where all other volcanism occurs. Instead it occurs at abnormally […]
What is half life of a reaction example?
What is half life of a reaction example? The half-life of a reaction is the time required for the reactant concentration to decrease to one-half its initial value. The half-life of a first-order reaction is a constant that is related to the rate constant for the reaction: t1/2 = 0.693/k. What is half life period […]
Do shells absorb CO2?
Do shells absorb CO2? This is because the chemical process by which these organisms convert calcium ions into shells is central to knowing how the oceans will – or will not – continue to act as a “carbon sink” that helps to soak up man-made carbon dioxide in the atmosphere. Do all seashells spiral the […]
How dangerous is phosphorus 32?
How dangerous is phosphorus 32? Phosphorus-32 is an energetic beta emitter which can penetrate up to 0.8 cm into living skin tissue. Therefore, this isotope poses an external (skin) dose hazard to persons as well as a potential internal hazard. What is the function of phosphorus 32? Phosphorus-32 (also known as P-32) treatment uses a […]
What happens if the buoyant force is less than the weight of an object?
What are positive effects of pollution?
What are positive effects of pollution? Examples of positive effects of pollution, from sunken cars as reefs attracting fish and kelp, to oil sludge used as food for protein-producing microorganisms. What are some positive impacts of water pollution? Why the Cost of Water Pollution is Measured: Water that is fresh in our sources, ponds, rivers, […]
Which type of cell is involved in communication?
Which type of cell is involved in communication? In that case, chemical signals on the outer cell membrane of one cell can directly engage receptors on the membrane of the other cell, and communication is especially fast. Typical synaptic communication takes place between neurons in the brain. What does it mean to say a cell […]
What happens to a cartridge when a gun is fired?
What happens to a cartridge when a gun is fired? A cartridge is inserted into the chamber. The action is closed, and the firing pin is pushed back and held back under spring tension. The trigger is squeezed, releasing the firing pin, which moves forward with great force. The firing pin strikes the primer, causing […]

How do you combine two reactions?
How do you combine two reactions? You combine multiple reactions into a single equation by listing all the reactants on the left side of the equation and all the products on the right side of the equation. Simplification of the overall equation will eliminate chemical species that exist on both sides of the equation without […]
