Answer:
For 1 antacid tablet (in ballon1) we get .0173 moles of CO2
for 2 tablets (in balloon 2) we get: 2*0,0173= 0.0346 moles of CO2
For 3 tablets (in balloon 3) we get 3* 0.0173 = 0.0519 moles of CO2
Explanation:
The complete question:
Calculate the theoretical value for the number of moles of CO2 that should have been produced in each balloon assuming that 1.45 g of NaHCO3 is present in an antacid tablet. Use stoichiometry (a mole ratio conversion must be present) to find your answers (there should be three: one answer for each balloon).
Balloon 1 had 1 antacid tab
Baloon 2 had 2
Balloon 3 had 3
Step 1: Data given
1.45 g of NaHCO3 is present in an antacid tablet
Molar mass of NaHCO3 = 84.00 g/mol
Step 2: The balanced equation
NaHCO3 + H2O → NaOH + H2O + CO2
Step 3: Calculate moles of NaHCO3
Moles NaHCO3 = mass NaHCO3 / molar mass NaHCO3
1.45g / 84.0 g/mol = .0173 moles
Step 4: Calculate moles CO2
For 1 mol NaHCO3 we need 1 mol H2O to produce 1 mol NaOH 1 mol H2O and 1 mol CO2
For 0.0173 moles NaHCO3 we'll get 0.0173 moles CO2
so for 1 antacid tablet we get .0173 moles of CO2
for 2 tablets we get: 2*0,0173 = 0.0346 moles of CO2
For 3 tablets we get 3* 0.0173 = 0.0519 moles of CO2

Equate the gravitational force to the electrostatic force:
<span>KC²/D² = Gm²/D² → C = m√[G/K] = 7.6√[6.67E-11/9E9] = 6.54E-10 coulombs </span>
<span>Number of electrons N = 6.24E18*C = 4.083E9 electrons</span>
Low clouds
Stratus clouds are uniform grayish clouds that often cover the sky. Usually no precipitation falls from stratus clouds, but they may drizzle. When a thick fog “lifts,” the resulting clouds are low stratus. Nimbostratus clouds form a dark gray, “wet” looking cloudy layer associated with continuously falling rain or snow. They often produce light to moderate precipitation.
Middle clouds
Clouds with the prefix “alto” are middle-level clouds that have bases at 6,500 to 23,000 feet up. Altocumulus clouds are made of water droplets and appear as gray, puffy masses, sometimes rolled out in parallel waves or bands. These clouds on a warm, humid summer morning often mean thunderstorms by late afternoon. Altostratus clouds, gray or blue-gray, are made up of ice crystals and water droplets. They usually cover the sky. In thinner areas of them, the sun may be dimly visible as a round disk. Altostratus clouds often form ahead of storms that produce continuous precipitation.
High clouds
Cirrus clouds are thin, wispy clouds blown by high winds into long streamers. They are considered “high clouds,” forming at more than 20,000 feet. They usually move across the sky from west to east and generally mean fair to pleasant weather. Cirrostratus, thin, sheetlike clouds that often cover the sky, are so thin the sun and moon can be seen through them. Cirrocumulus clouds appear as small, rounded white puffs. Small ripples in the cirrocumulus sometimes resemble the scales of a fish, creating what is sometimes called a “mackerel sky.”
Vertical clouds
Cumulus clouds are puffy and can look like floating cotton. The base of each is often flat and may be only 330 feet above ground. The top has rounded towers. When the top resembles a cauliflower head, it is called “cumulus congestus.” These grow upward and if they continue to grow vertically can develop into a giant cumulonimbus, a thunderstorm cloud, with dark bases no more than 1,000 feet above ground and extending to more than 39,000 feet. Tremendous energy is released by condensation of water vapor in a cumulonimbus. Lightning, thunder and violent tornadoes are associated with them.

It is a longitudinal wave.
