A reactionarrow simply indicates that something has changed and that one thing has become another.
A chemicalreaction is a process that converts one or more substances, known as reactants, into one or more different substances, known as products.
Chemical elements or compounds are examples of substances. A chemical reaction rearranges the constituent atoms of the reactants to produce various products.
The most important characteristics of events occurring in the universe are chemical reactions.
Plants grow, fruit development, and biodegrade towards becoming rich in nitrogen for new plants through chemical reactions.
Humans along with all other animals reproduce, digest, grow, heal, and think as a result of chemical reactions.
The arrow connects the old and new things (the thing that formed). An equation of reaction employs the reactionarrow. The reactant is the thing that reacted.
Thus, this is the chief meaning of the arrow in a chemicalreaction, the it shown the reactants combined to form products.

Answer: Static electricity will help in seed dispersal in cone bearing seeds.
Explanation:
Static electricity is the stationary electric charge produced by the friction. The static electricity can be produced by the turbulence or air currents in the storm clouds. This is responsible for the cause of lightening phenomena.
The cone bearing seeds exhibit cones that are hard and woody in nature. The static electricity due to the effect of lightening generate electrical shock which breaks open the cone and disperse the seeds. Thus the static electricity is important for seed dispersal in cone bearing trees.
The systematic name for the coordination compound [Cr(H2O)4Cl2]ClO3 is tetraaquadichlorochromium(III) chlorate.
The coordination compound you want to name falls under the subject of Chemistry, specifically inorganic Chemistry. The compound is [Cr(H2O)4Cl2]ClO3. The systematic name for this compounds is tetraaquadichlorochromium(III) chlorate. This nomenclature follows rules set out by Alfred Werner where the metal is specified (chromium), the number and type of ligands or ions the metal is bonded to are defined (tetraaqua, which indicates four water molecules, and dichloro for two chlorine ligands), and the oxidation state of the metal is given (III). Finally, the counter ion is named (chlorate).

For precipitation to happen, first tiny water droplets must condense on even tinier dust, salt, or smoke particles, which act as a nucleus. Water droplets may grow as a result of additional condensation of water vapor when the particles collide. If enough collisions occur to produce a droplet with a fall velocity which exceeds the cloud updraft speed, then it will fall out of the cloud as precipitation.
(2) distillation (4) sublimation
Answer:
(3) esterification
Explanation:
1) Deposition is a process in which a vapor directly condenses into a solid. It is the reverse of sublimation and therefore a process which involves a physical/phase change.
2) Distillation is a process in which a liquid mixture is separated based on the differences in their boiling points. This is a physical separation and not any form of a chemical change.
3)Esterification is an organic reaction in which a carboxylic acid is treated with an alcohol to form an ester.
4) Sublimation is again a physical/phase change process in which a solid gets converted into a gas.
