If a solid piece of naphthalene is heated and remains at 80 degrees C until is is completely melted, you know that 80 is the what?

Answers

Answer 1

Answer:

Answer: The given temperature is known as melting point of naphthalene.

Explanation:

Melting point is defined as the temperature at which solid gets converted to liquid.

The temperature remains constant until all the solid has been converted to liquid. At this temperature, solid state and liquid state are present at equilibrium.

$\text{Solid state}\rightleftharpoons \text{Liquid state}$

We are given:

A solid piece of naphthalene is heated till 80°C until all the solid is melted.

Hence, the given temperature is known as melting point of naphthalene.

Answer 2

Answer:

If a solid piece of naphthalene is heated and remains at 80 degrees Celsius until it is completely melted, you know that 80 degrees Celsius is the melting point of the solid naphthalene. This is the maximum temperature at which the chromium is in its solid form.

Which two compounds have the same molecular formula but different chemical and physical properties?(1) CH3CH2Cl and CH3CH2Br
(2) CH3CHCH2 and CH3CH2CH3
(3) CH3CHO and CH3COCH3
(4) CH3CH2OH and CH3OCH3

Answers

Answer is (4) - CH₃CH₂OH and CH₃OCH₃.

Both CH₃CH₂OH and CH₃OCH₃ have same molecular formula as C₂H₆O. But CH₃CH₂OH is an alcohol and CH₃OCH₃ is an ether.

Although two compounds have a same molecular formula, the atomic arrangement of those compounds differs from each other.

Hence, CH₃CH₂OH and CH₃OCH₃ are isomers of the formula C₂H₆O.

Due to the different arrangement of atoms, both compounds have different chemical and physical properties.

The answer is (4) CH3CH2OH and CH3OCH3. You need to figure out which pair has the same molecular formula which means that they have the same number of same atoms. Then you can get the write answer.

What are some factors that might cause our percent yield to be greater than 100%? What are some factors that might cause it to be less than 100%? Make sure you discuss specific cases of how both might happen.

Answers

In the field of science, usually, the product of an experiment iscomputed ahead to understand if it reached a specific objective. It would reachgreater than 100% of percent yield if the factors include faster reaction rates;proper handling of the reactants, no outside contaminants, and the procedure ofthe experiment is followed smoothly. It would reach lesser than 100% percent yieldif the experiment is not followed, external factors such as contamination fromthe environment (wind, moisture, etc).

When are atoms considered stable?when they have satisfied the law of conservation of mass naturally or through bonding to obtain
full valence shells

when they have satisfied the octet rule naturally or through bonding to obtain full valence shells

when their valence electrons have "fallen" back to ground state through bonding

Answers

Answer:

when they have satisfied the octet rule naturally or through bonding to obtain full valence shells

Explanation:

Generally, most atoms of an element are unstable because they have a void in their electron shell to fill, hence, they need to react with other elements to fulfil this task of octet.

Octet rule states that atoms of elements engage in reactions to form compounds so they can have eight (8) valence electrons in their shell. Noble gases e.g argon, neon etc. are elements that have naturally satisfied this octet rule by possession of 8 valence electrons in their shell. Other elements that do not have this naturally becomes reactive and enter bonding with other atoms to obtain full valence shells.
