bread rises because yeast acts on the sugar to produce carbon dioxide and alcohol. c^6h^12o^6 > 2 c^2h6^o + 2 co^2
sugar alcohol carbon dioxide

fill in the blanks with the correct amount of molecules
molecule(s) of dextrose sugar yields molecule(s) of ethyl alcohol plus molecule(s) of carbon dioxide through the action of yeast. the small amount of alcohol evaporates during baking. hydrogen atoms are involved in this reaction.

Imagine if during the cathode ray experiment, the size of the particles of the ray was the same as the size of the atom forming the cathode. which other model or scientific observation would have also been supported? 1. this would support dalton's postulates that proposed the atoms are indivisible because no small particles are involved. 2. this would support bohr's prediction about electrons moving in orbits having specific energy. 3. this would support bohr's prediction about electrons being randomly scattered around the nucleus in the atom. 4. this would support dalton's postulates that proposed that atoms combine in fixed whole number ratios to form compounds.

Will a solution form when the solvent and solute are both nonpolar? a. not likely b. never c. most likely

Dumbledore decides to gives a surprise demonstration. he starts with a hydrate of na2co3 which has a mass of 4.31 g before heating. after he heats it he finds the mass of the anhydrous compound is found to be 3.22 g. he asks everyone in class to determine the integer x in the hydrate: na2co3·xh2o; you should do this also. round your answer to the nearest integ
