A lit candle needs to draw oxygen from the air in order to continue burning. ... Thus, oxygen inside the glass jar will decrease and it gets filled with carbon dioxide, and eventually the candle's flame will Extinguish.
Answer:
when the pH increases suddenly in the flask
Explanation:
I think it's right. :)
Electron - In an atom, the central part which is composed of neutrons and protons including quarks is called the nucleus. Whereas the electron is the particle with negative elementary electric charge can be found inside the atom surrounding the nucleus.
Given that the question gives us concentration (M) and volume, we can use these so get moles. remember that Molarity (M)= mol/ Liters, so if we want the moles, then
moles= M x L
moles= 1.13 x 5.60= 6.33 moles KI
now to get the mass in grams, we need the molar mass of potassium iodide (KI) which can be determined using the periodic table and add the masses of each atom.
molar mass KI= 39.1 + 127= 166.1 g/mol
6.33 mol (166 g/ 1 mol)= 1050 grams KI
