Sodium hydrogen carbonate nahco3 , also known as sodium bicarbonate or "baking soda", can be used to relieve acid indigestion. acid indigestion is the burning sensation you get in your stomach when it contains too much hydrochloric acid hcl , which the stomach secretes to digest food. drinking a glass of water containing dissolved nahco3 neutralizes excess hcl through this reaction: hcl (aq) nahco3 (aq) â nacl (aq) h2o (l) co2 (g) the co2 gas produced is what makes you burp after drinking the solution. suppose the fluid in the stomach of a man suffering from indigestion can be considered to be 250.ml of a 0.076 m hcl solution. what mass of nahco3 would he need to ingest to neutralize this much hcl

Hannah is writing a report on how albedo affects the global climate. she’s proofreading her passage for any factual errors. which sentence must hannah correct before submitting her report? earth receives energy from the sun. this energy drives many of the processes on earth, including its climate. some part of this energy is reflected by earth’s surface. we use the term albedo to describe the reflected energy. albedo of an object is the ratio of the reflected radiation to the total radiation reaching the object. a value of 0 means no energy is absorbed by the object, whereas a value of 1 means that all of the energy is absorbed. in this way, the albedo of an object can influence earth’s atmospheric temperature.
