How are ions formed? Why are some ionic compounds insoluble? What are coordination complexes and how do they form? Will the given solid compound dissolve in water? Why or why not? PbO2 What process changes a chlorine atom, Cl, into a chloride ion, Cl-?
How are non-metal compounds formed? Is calcite a carbonate mineral? What is the difference between organic and inorganic minerals? Is pyrite a common sulfide mineral? Are minerals and rocks the same? Is quartz a sulfide mineral? How do crystalline solids form their patterns from ionic compounds...
Coral reefs, often hailed as the rainforests of the sea, are some of our planet's most biodiverse and complex ecosystems. These underwater cities, teeming with life, are the architects of the underwater world, shaping the very structure of the ocean floor. But how do these majestic structure...
Did you really pay attention to how much you drank before you got on the road, or are you just guessing? Don't worry, the police can help you out with that. ANATOLII BOIKO/Stringer/Getty Images We hear and read about drivers involved in an accident who are later charged with drunke...
The best solution is to neutralize the Skunk odor using the following formula to actually change the chemical structure of the compounds in skunk spray that make it smell so bad, and stick around for such a long time. It’s sciency-stuff, so we won’t get into it too deeply – and ...
Butterflies' lives are all about flight. Their vibrant wings are the largest, most visible parts of their bodies, and they spend much of their time in the air. Flying takes a lot of energy, and to get this energy, butterflies drink the nectar from flowers, which require the power of fli...
Rhodopsin breaks down into several intermediate compounds, but eventually (in less than a second) forms metarhodopsin II (activated rhodopsin). This chemical causes electrical impulses that are transmitted to the brain and interpreted as light. Here is a diagram of the chemical reaction we just ...
Knowing when to use an '-s' or an '-es' on a plural can be hard and frustrating. The rules may seem arbitrary, but here's a simple guide to correct pluralization.
let G(x) = 8x³ – 125. Then factoring this third-degree polynomial relies on a difference of cubes as follows: (2x – 5) (4x² + 10x + 25), where 2x is the cube-root of 8x³ and 5 is the cube-root of 125. Because 4x² + 10x + 25 is prime, you are done factorin...
While not all phrasal compounds are idiomatic, some are and cause confusion for English language learners. For example, the phrasal verb "putting me off" does not mean the same thing as the words taken by themselves. The phrase means to ignore or to avoid someone. When taken separately, ...
