What does it mean when a system or a reaction is endothermic?

Chemistry

vitfil [10]3 years ago

When a chemical reaction is endothermic, it means that the energy needed to break the bonds in the reactants is greater than the energy released when all of the new bonds are formed in the product. During an endothermic reaction, the reaction will absorb energy from its surroundings.

This is the opposite of an exothermic reaction, where the reaction releases energy because the energy needed to break the bonds in the reactants is less than the energy created in the product.

Which process transfers heat from the ground to the air touching it? Conduction Convection Evaporation Radiation
Delicious77 [7]

Convection

Explanation:

Heat is a form of thermal energy borne as result of thermal energy. It is observed as temperature differences between places.

There are different types of heat transfer:

  • Conduction
  • Convection
  • Radiation

Conduction is a heat transfer which involves the actual movement of the collision of the molecules of the medium.

Convection is a heat transfer in fluids by their movement from areas of higher to places of lower heat.

Radiation is heat transfer using electromagnetism and does not involve molecules of the medium

The process of heat transfer from ground to the air touching it is convection. It involves particles of the air.

A molecule with a trigonal bipyramidal electron geometry must have a central atom with how many bonding and nonbonding electron
Flura [38]

A molecule with a trigonal bipyramidal electron geometry must have a central atom with how many bonding and nonbonding electron groups around it Equatorial.

A molecule is made up of one or more atoms. If they contain multiple atoms, those atoms can be the same (the oxygen molecule has two oxygen atoms) or different (the water molecule has two hydrogen atoms and one oxygen atom). Biomolecules such as proteins and DNA are made up of thousands of atoms.

Water is a simple molecule with one oxygen atom bonded to two different hydrogen atoms. The bond is a polar covalent bond (polar bond) due to the high electronegativity of the oxygen atom. On this page, you can find 47 synonyms, antonyms, idioms, and related words for molecules such as particles, ions, speckles, fragments, electrons, chittles, spots, nuclei, iota, peptides, and macromolecules.

Given the speed of light (3.00 × 108 m/s) and a wavelength 5.9 × 10-7 m, what is the frequency?
Cerrena [4.2K]
Wavelength x Frequency = Speed

So, 5.9 x 10^-7 x F = 3 x 10^8

Rearranging the equation, we get:
F = (3 x 10^8)/(5.9 x 10^-7) = 5.08 x 10^14 Hz

Hope I helped!! xx
