3. A car going south 35 mi/hr speeds up when the speed limit changes. It takes 0.05 hours to
accelerate at a rate of 200 mi/hr? What is the
car's final velocity?

Cr(oh)3 -> cr(3+) + 3oh-

Matter- occupies space and possesses rest massno matter is the opposite

Elements would be the right answer

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.
