In the carbon dioxide (sodium bicarbonate tablety experiment, two tablets were placed in one bottle. The temperature of that bottle after an hour was 86 degrees The other bottle was at 77 degrees. The tablets released carbon dioxide into the bottle. How did the carbon dioxide affect the temperature?

The equation of the chemical reaction is NaHCO3 + H+ --> H2O + CO2 + Na

To determine the total number of moles of carbon dioxide, the given mass of sodium hydrogen carbonate is divided with its own molar mass. Then it is multiplied with the ratio between NaHCO3 and carbon dioxide. The total number of moles of CO2 one tablet should yield is 0.024 mole.

the oxygenated blood then leaves the lungs through pulmonary veins, which return it to the left heart, completing the pulmonary cycle. this blood then enters the left atrium, which pumps it through the mitral valve into the left ventricle. from the left ventricle, the blood passes through the aortic valve to the aorta.

deoxygenated blood leaves through the right ventricle through the pulmonary artery. from the right atrium, the blood is pumped through the tricuspid valve (or right atrioventricular valve), into the right ventricle.

i think that you are smart and you should fit for it out
