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)→nacl(aq)+h2o(l)+ co2(g)

the co2gas produced is what makes you burp after drinking the solution. suppose the fluid in the stomach of a woman suffering from indigestion can be considered to be 200.ml of a 0.089m hcl solution. what mass of nahco3 would she need to ingest to neutralize this much hcl? be sure your answer has the correct number of significant digits.

1.4952 grams of sodium bicarbonate she  would need to ingest to neutralize this much HCl.

Explanation:

Moles of hydrochloric acid = n

Volume of hydrochloric acid solution = 200.0 mL = 0.200 L

Molarity of the hydrochloric acid = 0.089 M

of HCL

According to reaction, 1 mole of HCl is neutralized by 1 mole of sodium bicarbonate.

Then 0.0178 moles of HCl wil be neutralized by :

of sodium bicarbonate

Mass of 0.0178 moles of sodium bicarbonate:

0.0178 mol × 72 g/mol = 1.4952 g

1.4952 grams of sodium bicarbonate she  would need to ingest to neutralize this much HCl.

why is cellular respiration important for homeostasis?

it changes food into energy that the organism can use.

which of the following is most likely to happen if a cell is not able to divide?

the cell will not be replaced when it is damaged.

explanation:

the number of valence electrons for each molecule or ion is shown beneath the structure. remember hydrogen will not have more than two electrons. this hydrogen is part of a covalent bond (sharing two electrons). a double bond here would cause hydrogen to share four electrons with phosphorus.
