What is the change in enthalpy for the combustion reaction of butane, c4h10? 2c4h10(g) + 13o2(g) → 10h2o(g) + 8co2(g) given: c4h10(g): δhf °= –125 kj h2o(g): δhf °= –242 kj co2(g): δhf °= –393.5 kj –510.5 kj –5318 kj –54468 kj –5818 kj done

The answer is tea due to the main ingredient being a herb that grows from the ground and sugar that grows from a stalk, i hope this : )     p.s.  can i be brainliest?

Answer earth,water,fire and air;

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.
