<h3><u>Answer;</u></h3>

2)E generally decreases from right to left.

<h3><u>Explanation;</u></h3>
  • <em><u>The E or the Electronegativity is related to a period of elements as in increases across the period from right to left.</u></em>
  • <em><u>The E increases across the period due to the increase in the amount of charge in the nucleus of an atom, which means the nucleus will attract the bonding pair of electrons more strongly.</u></em>
  • As you move down the group the electronegativity will decrease because the number of energy levels increases and thus the outer electrons are very far away from the pull of the nucleus.

marysya [2.9K]

explanation: Synthetic fiber or synthetic fibre (in British English; see spelling differences) are fibers made by humans through chemical synthesis, as opposed to natural fibers that are directly derived from living organisms. They are the result of extensive research by scientists to improve upon naturally occurring animal and plant fibers. In general, synthetic fibers are created by extruding fiber-forming materials through spinnerets, forming a fiber. These are called synthetic or artificial fibers. Synthetic fibers are created by a process known as polymerization, which involves combining monomers to make a long chain or polymer. The word polymer comes from a Greek prefix "poly" which means "many" and suffix "mer" which means "single units". (Note: each single unit of a polymer is called a monomer). There are two types of polymerization: linear polymerization and cross-linked polymerization.

How do I balance "Lithium hydroxide + hydrogen acetate --&gt; lithium acetate + water"
matrenka [14]

Answer:

LiOH+CH3COOH=C2H3LiO2+H2O balanced equation

Explanation:

lithium hydroxide-> LiOH

hydrogen acetate->CH3COOH

lithium acetate->C2H3LiO2

water->H2O

LiOH+CH3COOH=C2H3LiO2+H2O

Li=1,O=3,H=5,C=2 --> Li=1,O=3,H=5,C=2

the two sides have same numbers so it is balanced.

Which element will form covalent bonds with chlorine?
maxonik [38]

Hydrogen on sharing its one electron with chlorine results in formation of hydrogen chloride molecule and chlorine and hydrogen complete its octet by sharing one electron of each and thus forming a single covalent bond by sharing of two electrons.
