There are only 5.5. x 10^12 metric tonnes of fossil fuels that can be used as a useful resource existing on Earth. Assuming an estimated rate of fossil fuel use of 1 x 10^11 metric tonnes per year, calculate an order of magnitude estimation of the time left before the fossil fuel reserves run out.

Answerstrong acids and bases completely dissociate in water.this is how strong acids and bases are defined. they will ionize 100% in solution, making a non-reversible reaction

Answer//the law of conservation of mass.;

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.
