aliina [53]
<h2>Answer : Option D) Solutions of salt and water conduct electricity. </h2><h3>Explanation :</h3>

The best description of salt is that when they are dissolved in water they dissociate into ions and become electrolytic in nature. This is observed that these solutions of salt will conduct electricity. Dissociation of ions helps the solution to conduct electricity. Usually salts dissociate into respective cations and anions of the salt compound. Most of the salts can be obtained as a product from neutralization reactions.

What is the solution to the problem expressed to the correct number of significant figures?
anyanavicka [17]

Answer:

8700

Explanation:

First, do the operations i<em>nside parentheses</em>.

102 900/12 = 8600     2 sfs because of 12

170/1.27 = 130              2 sfs because of trailing 0 in 170

===============

Now, do the addition.

 8600

<u>  + </u><u>13</u><u>0 </u>

8700

The answer has two significant figures because when adding, you must round your answer to the same "place" as the measurement with its last significant figure furthest to the left.  

The last significant figure in 8600 (the 6, in the hundreds place) is further to the left than the last significant figure in 130 (the 3, in the tens place).

We round off to the nearest hundred and get the answer, 8700.
