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 help digest food. Drinking a glass of water containing dissolved NaHCO3 neutralizes excess HCl through this reaction: The CO2 gas produced is what makes you burp after drinking the solution. Suppose the fluid in the stomach of the man suffering from indigestion can be considered to be 50 mL of a 0.034 M HCl solution. What mass of NaHCO3 would he need to ingest to neutralize this much HCl?

Be sure your answer has the correct number of significant digits.

What would be the independent, dependent, and controlled(need 3 controlled variable) variables in this lab?

- what would be a good hypothesis?

- for the second reaction, my teacher told us to change something in the lab and see how much gas forms after that, what would be something that we should change?

lb this lab we will be using our knowindge of stoicbiometry as well s the ideal gas law to calculate the amount of gas foemed in a chemical around-the-world balloos fights, they need to it is best for them to make these calculations before the flight rather during a chemical reaction. From this value, you can determine nation wen us the pere ent error. The ideal gas law can be used for many things For exampie, when hor air balloonists attempt caiculate how much gas they will have in thelr balloons at any time. Depending on the weight of than abruptly find out whilehalfway of the Indian Occan. During this lab, you will be determining the actual and peroent error of the reaction 1) Weigh out approximastely 5.0 g of NaHCO, (aka baking soda) on the balance. Record the exact amount of NaHCOs you 3) Pour the NaHCO, into a large deflated balloon using the plastic funnel When all of it 4) Very carefully place the balloon over the mouth of the flask, making sure that the meesured Pour 150 ml of IM HCI into a 250 ml Erlenmeyer flask make sure that all of it is in the main part of the balloon and none is in the opening has been added, tap the side of the balloon to NaHCO, does not fall into the flask. You may need pinches off the neck of the balloon to t0 to have one person stretching the mouth of the bailoon over the mouth of the flask while asodser p keep the powder from coming out Make sure that you're careful while doing this, because it will be easy for you t some of the acd on yourser while doing this. Wear safety goggles during this part of the lab, and if you splash acid on yourselt, make sure you wash it off with plenty of water 5) Once the balloon has placed over the mouth of the flask, have one person held it on so that it cannot fall off Once that person is ready and balloon is firmly fassened, another person should release all of the powder from the balloon inso the bydrochlonc lask You will immediately observe the forma on of bubbles a dor f an while the balloon inflates, the person holingä¼½ al should make sure that none of the gas escapes acid in the the balloon 6) When the reaction has stopped, take the balloon off the flask and tie off the end so it is closed. With a paper towel wipe off amy liqud which has splashed up into the nozzle oft eballon; this is very likely acadic, so make sure to wash your hands after touch ng 7 With a string and a ruler, find the circumference of the balloon in centimeters 8) Pour the solution into the waste container.
