1a. A researcher accidentally spilled some sand into his beaker containing crystalline compound X. Knowing what he did about mel

Sunny_sXe [5.5K]

Answer:

See explanation

Explanation:

Many organic compounds have low melting points. This is due to the fact that many of these compounds are non polar.

However, compound X is slightly polar but still has a melting point which is far less than that of sand composed of a high melting point inorganic material.

Since sand has a much higher melting point compared to compound X, the researcher need not be worried that sand was spilled into his beaker.

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