Calculate the mass of khc8h4o4 that reacts with 15 ml of the naoh solution
dlinn [17]
The balanced chemical reaction would be:

 KHC8H4O4<span> (aq) + </span>NaOH<span> (aq) → NaKC8H4O4 (aq) + H2O.

The concentration of the NaOH is equal 0.1 M. We use this and the volume given above to determine the mass of KH</span>C8H4O4. We do as follows:

0.1 mol / L NaOH (.015 L) ( 1 mol KHC8H4O4 / 1 mol NaOH) (204 g / 1 mol) = 0.306 g KHC8H4O4

B. Line 2 has a mistake

Explanation:

1. All electromagnetic waves are made of both electric and magnetic fields (hence the name electromagnetic).

2. All electromagnetic waves are transverse, and not longitudinal.

3. All electromagnetic waves can travel through space because they do not need particles to travel (like sound waves).

4. Electromagnetic waves all travel at the speed of light (299 792 458 m/s).
