Abiotic factors are non-biological parts of a living ecosystem that affect its ability to survive. Common types of abiotic factors...
Covalent bonds that are polar have an unequal sharing of a pair of electrons. This would be determined by an electronegativity difference of the two elements falling between 0.4 and 1.7. Non-polar bonds have less than 0.4 electronegativity difference. What is an example of a nonpolar covalent bo...
How come two non-polar substances are able to easily mix? What makes extremely heavy elements so unstable? What are superacids? How are these formed and how do they work ? What type of process is involved in going from element to compounds and vice versa?
The abiotic spheres—comprising the lithosphere, atmosphere, and hydrosphere—are made up of non-living components. Abiotic factors include elements such as minerals, gases, and water, all of which do not originate from living organisms. These spheres interact with each other and influence the Earth...
NaCl is a polar molecule. NaCl is a chemical formula for Sodium Chloride, and it is made of one Sodium atom and one chlorine atom. The atoms of both Sodium and Chlorine are arranged in an organized pattern, also known as a lattice. To know the polarity of any molecule, we first look...
Answer to: (a) What are the properties of elements and compounds? (b) How are properties of a compound related to elements that comprise it? By...
each bit: logic 0, also called low, and logic 1, also called high. In a closed circuit, these logic elements are represented by DC voltages. A high-speed data signal varies rapidly between the low and high states. Common values are approximately +0.5 volts for low and +5 volts for ...
What kind of elements form polar covalent bonds? Is H2CO polar or nonpolar? What intermolecular force is responsible for the attraction between an ion and a polar molecule? What is a tetrahedral molecule? Identify the bonds in the compound CNH5 as polar or non-polar. ...
Brittle stars have internal skeletons, and each segment of their arms are made of a cluster of small skeletal elements (ossicles). Researchers in the past have made the assumption that differences in the shape of these ossicles between species change how they move, but I wasn’t so sure. ...
How can you tell the difference between an ionic and a covalent bond between elements? Classify the bonding as ionic or covalent and explain why? a) HI b) NaI What is the difference between ionic bonds, covalent bonds, and polar covalent ...
