A compound has the molecular formula

Chemistry
1 answer:
Anna [14]3 years ago
5 0

Answer:

Well, this compound is an organic compound, that the solid state at room temperature is determined by the joints it has and the type, strength and location of the joints or bonds.

Solid bodies, on the other hand, are those that maintain constant shape and volume thanks to the great cohesion of their molecules. The solid phase is one of the four states of matter aggregation, together with the liquid, the gaseous and the plasma

Explanation:

Regarding that it has non-polar molecules, this will influence its solubility or what type of solvents may be diluted and in which not.

Apolar molecules are those molecules that are produced by the union between atoms that have the same electronegativity, so the forces with which the atoms that make up the molecule attract the electrons in the bond are the same, thus causing the cancellation of said forces.

In this molecule, each oxygen atom attracts the shared electrons towards itself with the same intensity but in the opposite direction, so that the attractive forces are canceled and the molecule does not convert, it becomes a dipole. Furthermore, they can be identified through the Lewis structure with free pairs, that is, if it has free pairs, it is polar and if it does not, it is apolar.

In order to take into account in relation to the organism or if not a good example, the lipid structures of our organism have polar and non-polar sides, these non-polar sides are in charge of challenging hydrophilicity, since the apolar part or not NEVER will have an affinity for water, therefore it will not dissolve in it, something similar would happen with this chemical compound that we are talking about.

This is why when having non-polar molecules we can say that we are dealing with a hydrophobic compound or that it does not dissolve in water.

Discuss FOUR ways in which one's acceptance of responsibility can influence
andrew11 [14]

Answer:

being responsible is owing up to the possible

consequences of your decision whether it was right or wrong.

communication is a two way process in which there is a messenger and receiver

one of the ways by which a person could be responsible is by saying 'I'

in all the things he would say, instead of 'we'

for example , " We don't like the way you acted a while ago " , change it to i don't like tye way you acted a while ago.

here u r establishing ownership on the things you want to say to the person

What do all group 2 elements have in common? (2 points) they all gain two electrons to form a stable outer energy level. They fo
NemiM [27]
The correct answer would be the last option.  The property that is common to all group 2 elements is that they  tend to form ionic bonds by losing electrons making these atoms positive charge. They are called cations. These elements are beryllium, magnesium, calcium, strontium, and radium.

In acidic aqueous solution, the purple complex ion Co(NH3)5Br2+ undergoes a slow reaction in which the bromide ion is replaced b
kirill115 [55]

Answer:

A) 0.065 M is its molarity after a reaction time of 19.0 hour.

B) In 52 hours [Co(NH_3)5Br]^{2+} will react 69% of its initial concentration.

Explanation:

Co(NH_3)_5(H_2O)_3+[Co(NH_3)5Br]^{2+}(Purple)(aq)+H_2O(l)\rightarrow [Co(NH_3)_5(H_2O)]^{3+}(Pinkish-orange)(aq)+Br^-(aq)

The reaction is first order in [Co(NH_3)5Br]^{2+}:

Initial concentration of [Co(NH_3)5Br]^{2+}= [A_o]=0.100 M

a) Final concentration of [Co(NH_3)5Br]^{2+} after 19.0 hours= [A]

t = 19.0 hour = 19.0 × 3600 seconds ( 1 hour = 3600 seconds)

Rate constant of the reaction = k = 6.3\times 10^{-6} s^{-1}

The integrated law of first order kinetic is given as:

[A]=[A_o]\times e^{-kt}

[A]=0.100 M\times e^{-6.3\times 10^{-6} s^{-1}\times 19.0\times 3600 s}

[A]=0.065 M

0.065 M is its molarity after a reaction time of 19.0 h.

b)

Initial concentration of [Co(NH_3)5Br]^{2+}= [A_o]=x

Final concentration of [Co(NH_3)5Br]^{2+} after t = [A]=(100\%-69\%) x=31\%x=0.31x

Rate constant of the reaction = k = 6.3\times 10^{-6} s^{-1}

The integrated law of first order kinetic is given as:

[A]=[A_o]\times e^{-kt}

0.31x=x\times e^{-6.3\times 10^{-6} s^{-1}\t}

t = 185,902.06 s = \frac{185,902.06 }{3600} hour = 51.64 hours ≈ 52 hours

In 52 hours [Co(NH_3)5Br]^{2+} will react 69% of its initial concentration.

How are fluids used and controlled in manufactured devices?
BlackZzzverrR [31]

Answer:

Fluid power systems perform work by a pressurized fluid bearing directly on a piston in a cylinder or in a fluid motor. A fluid cylinder produces a force resulting in linear motion, whereas a fluid motor produces torque resulting in rotary motion. Within a fluid power system, cylinders and motors (also called actuators) do the desired work. Control components such as valves regulate the system.
