A solution used to chlorinate a home swimming pool contains 7% chlorine by mass. An ideal chlorine level for the pool is 1 part per million (1 ppm). Think of 1 ppm as being 1 chlorine per million grams of water. What volume of chlorine solution, in liters, is required to produce a chlorine level of 1 ppm in an 18,000-gallon swimming pool?

H tricky one let me think and get back to u

The percentage of the rock record is 66%plz mark me brainliest! hope this !

According to arrhenius theory of acid and bases, an acid is a proton donor, while base donates hydroxyl ions. further, acid and base reacts to form salt and water.consider following example.hcl    +      h2o          →      cl-          +      h3o+here, hcl has donated a proton, hence it is an acid.now consider following reactionhcl      +      naoh            ↔      nacl      +        h2oin this reaction, hcl donates proton, hence it is acid. on other hand, naoh donates hydroxyl ion (i.e. hence it is a base.
