Answer:

Explanation:

Polar molecules interact with other molecules of similar polarity to form solutions. Non-polar molecules do not interact the same way.

Answer:

The scientists predict the polarity of molecules and the distribution of non polar and polar molecules by finding out the net dipole moment of the molecular structure.

Explanation:

The net value of dipole moment is found out with the help of finding the bond angle between the atoms of the given molecule along with the distance between the atoms and the charge on the atoms of the molecule.

This will be applied in the appropriate formula which tells whether the molecule is polar or non polar.

A piece of unknown metal weighs 348g. When the metal piece absorbs 6.64kj of heat , its temperature increases from 24.4C to 43.6

Morgarella [4.7K]

Answer:

This metal could be the aluminium with a specific heat of $H = 993 \frac{J}{kgC}$

Explanation:

A pie of unknown metal presents a mass (M) of 348 g. This metal is heated using energy (E) of 6.64 kJ and the temperature increases from T1 =24.4 to T2 =43.6°C. We can calculate the specific heat (H) of this metal as follows

$H = \frac{E}{M*(T2-T1)}$

We can replace previously presented data in this equation. After simplifying and converting to adequated units, we found that

$H = \frac{6640 J}{0.348 Kg*(43.6-24.4) C} =\frac{6640 J}{6.686 KgC}$

Finally, the specific heat of this metal is

$H = 993 \frac{J}{kgC}$

The aluminium could be the metal, its specific heat is similar to that found in this problem.

Finally, we can conclude that this metal could be the aluminium with a specific heat of $H = 993 \frac{J}{kgC}$

Which factor is generally responsible for high melting points?

kherson [118]

The factor that is generally responsible for higher melting point is intermolecular forces. The compounds that are covalent in nature are made of molecules rather than ions. It has been seen that some of the covalent compounds have polar molecules at one end, due to which the one end has more electronegative force than the other. The electrostatic force that is bounding the compound is the main cause of higher melting point of this compound. So it is true that with the increase of polarity of a compound creates higher melting point. .. hope I helped

Write a note on Polygenic disorder.

Lorico [155]

Answer:

a note? well alright

Explanation:

Polygenic disease: (the defintion)

A genetic disorder that is caused by the combined action of more than one gene.

Polygenic conditions: hypertension, coronary heart disease, and diabetes.

This is so because such disorders depend on the simultaneous presence of several genes, they are not inherited as simply as are single-gene diseases.
