Answer: Option (C) is the correct answer.

Explanation:

Relation between pH and hydrogen ion concentration is as follows.

          pH = -log[H^{+}]

It is given that hydrogen ion concentration is 1 \times 10^{-12} M. Therefore, putting this value in the above formula as follows.

         pH = -log[H^{+}]

               = -log[1 \times 10^{-12}]

               = - (-12) (log [1] + log[10])                 (log[1] = 0 and log[10] = 1)      

               = 12

As pH = 12, hence the solution will be highly basic. As a result, there will be high concentration of hydroxide ions.

c) A substance has a high melting point and conducts electricity. What type of structure does it have
trapecia [35]

Answer:

Metallic structure

Explanation:

They have a high melting point due to the strong forces of attraction between the positive ions (cations) and the delocalised electrons. Moreover, they conduct electricity due to the sea of delocalised electrons.

<em>[Extra: It could be an ionic compound since they also have a high melting point, however they only conduct electricity in liquid or aqeouus state.]</em>

A filament of a light bulb is made from a pure sample of tungsten.
GenaCL600 [577]

Answer:

The correct options are:

1) Pure chemical substance

2) Element.

Explanation:

each of the term is explained below:

1) <u>Mixture: </u> Since tungsten is an element in periodic table thus it is not a mixture.

2) False by definition of mixture.

3) false by definition of mixture.

4) <u>Solution:</u> Tungsten in a filament is in solid form hence solution is incorrect.

5) Since it is given in the question itself that the sample is pure hence option 'E' is correct as chemical substance is a pure substance that has a homogeneous composition and the sample in the question is given as pure.

6) <u>Compound:</u> By definition of compound it is formed by mixing 2 or more elements but since tungsten is an element that occurs independently in nature hence it is not a compound.

7) Tungsten is a element in the periodic table with atomic number 74.
