What does the double ended arrow indicate in the following chemical equation? The double-ended arrow in the chemical equation indicates a reversible reaction. A reversible reaction is a reaction in which the conversion of reactants into products and the conversion of products into reactants can happen simultaneously. What does the arrow in a chemical reaction […]
Is it better to get fit before playing sports or play sports to get fit?
Is it better to get fit before playing sports or play sports to get fit? Being fit is very important to overall health. However, when looking at sports performance the goals tend to be more specific and the level of training higher. Just by being fit does not necessarily mean that one is ready for […]

Is fracking good or bad?
Is fracking good or bad? In the U.S. alone, around 13 million metric tons of methane is released annually from natural gas wells alone. Fracking well sites are the source of a number of other air pollutants, which are less common than methane, but arguably more harmful to local populations. Where is fracking banned? Four […]
What are the hazards of magnesium?
What are the hazards of magnesium? ► Exposure to Magnesium may cause “metal fume fever.” This is a flu-like illness with symptoms of metallic taste in the mouth, headache, fever and chills, aches, chest tightness and cough. The symptoms may be delayed for several hours after exposure and usually last for a day or two. […]
What are the disadvantages of using aluminum wire?
What are the disadvantages of using aluminum wire? The disadvantage of aluminum wiring is that it must be installed correctly to avoid the risk of house fires. When a current runs through aluminum wiring it causes the metal to expand. This creates a cycle of expanding and contracting called “cold creep.” In time, this can […]
Which can show resonance?
Which can show resonance? Resonance is shown by toluene which contains alternate single and double bonds in a planar six-membered ring. Was this answer helpful? Why is ozone a resonance structure? Ozone, or O3 , has two major resonance structures that contribute equally to the overall hybrid structure of the molecule. Both structures account for […]
What is the purpose of a reference?
What is the purpose of a reference? Referencing allows you to acknowledge the contribution of other writers and researchers in your work.

Where is foreshortening used?
Where is foreshortening used? Foreshortening is a technique used in perspective to create the illusion of an object receding strongly into the distance or background. The illusion is created by the object appearing shorter than it is in reality, making it seem compressed. Are foreshortening and perspective the same thing? Perspective is the mathematical rule […]
What is Gauss law for electric flux?
What is Gauss law for electric flux? Gauss’s law states that: The net outward normal electric flux through any closed surface is proportional to the total electric charge enclosed within that closed surface. How do you fix electric flux problems? Solution: To compute electric flux, we need the magnitude of the electric field, area of […]
