The sun generates energy from a process called nuclear fusion. During nuclear fusion, the high pressure and temperature in the sun's core cause nuclei to separate from their electrons. Hydrogen nuclei fuse to form one helium atom.
Answer:
- <u>Find out the concentraion of the acetic acid, calculate the number of moles, which is equal to the number of moles of baking soda, and then multiply by the molar mass of baking soda to convert to mass in grams.</u>
<u></u>
Explanation:
You need the concentration of the <em>acetic acid.</em>
With the concentration you can find the number of moles of acid in the given 100mL of acetic acid solution.
- # of moles = molar concentration × number of liters of solution
By stoichiometry of the reaction, you determine the number of moles of <em>baking soda</em>:
CH₃COOH(aq) + NaHCO₃(aq) → CH₃COONa(aq) + CO₂(g) + H₂O(aq)
↑ ↑ ↑
<em>acetic acid baking soda gas</em>
From that balanced molecular equation, you find that 1 mole of acetic acid react with 1 mole of baking soda.
Then, using the molar mass of bakind soda, you convert the number of moles into mass in grams:
- mass in grams = number of moles × molar mass.
Then, adding that mass of baking soda, may be a little excess to be sure, all the acetic acid would be consumed getting the <em>largest amount of gas possible.</em>
It is 6 which is the atomic number of carbon.
Well, which weighs more? 2 tons of bricks or 2 tons of feathers? A lot of people would say bricks. But no, you just have to use a lot more feathers to equal the same weight. That is what you are looking for here. It weigh the same no matter what you put in it.
