Answer:

Condensation

Explanation:

Matter can be broadly classified into three states:

-Solid

-liquid

-gas

In the solid state, molecules are held by very strong intermolecular forces which decrease in the liquid and further lowered in the gaseous state. Therefore, solids are the most condensed state followed by the liquid and finally the gas phase.

-Boiling and evaporation involve phase change from liquid to gas i.e. more condensed to less condensed

- Melting involves phase change from solid to liquid i.e. more condensed to less condensed

- Condensation involves phase change from gas to liquid i.e. less condensed to more condensed

Given the following Fischer projection: Fischer projection for an entantiomer of 2-bromo-2,3-dihydroxypropanal with the bromine
harina [27]

Answer:

Explanation:

Stereoisomers are two or more atoms that  have the same bonding order of atoms but there is a difference  spatial arrangement of  the  atoms in space.

A plane of symmetry divides a molecule into two equal halves.

A chiral stereoisomer are not superimposed on a mirror image , Hence they do not posses a plane of symmetry.

As a result to that. these non-superimposable mirror images are said to be Enantiomers.

However, a Fischer Projection emanates from a two - dimensional figure which is used for presenting a three - dimensional organic molecules.

From the given question;

Fischer projection for an enantiomer of 2-bromo-2,3-dihydroxypropanal with the bromine oriented horizontally to the left and the hydroxide group oriented horizontally to the right.

we can sketch the way the enantiomer of 2-bromo-2,3-dihydroxypropanal can  be seen like the one shown below:

              CH₂OH

                   |

                   |

                   |

Br -------------|----------------OH

                   |

                   |

                   |

                 CHO

The objective of this question is to drawn the perspective formula of the molecule.

So , from the attached file below; we can see the perspective formula of the molecule in a well structured 3-D format.

When 1.0 mole of MgSO4 is dissolved in water contained in a calorimeter, the temperature of the water and dissolved ions increas
KatRina [158]

Answer: negative , from , to , exothermic

Explanation:

An endothermic reaction is a type of chemical reaction in which energy is absorbed from the surrounding. The temperature of the surrounding decreases.

An Exothermic reaction is a type of chemical reaction in which energy is released into the surrounding. The temperature of the surrounding increases.

Endothermic reactions are those in which heat is absorbed by the system from the surroundings and exothermic reactions are those in which heat is released by the system to the surroundings. \Delta H  for Endothermic reaction is positive and  

As on dissolution of salt, the temperature of water increases, the heat has been released from system into surroundings and thus \Delta H is negative.
