Explanation:
mass H2O2 = 55 mL(1.407 g/mL) = 80.85 g
molar mass H2O2 = 2(1.01 g/mol) + 2(16.00 g/mol) = 34.02 g/mol
moles H2O2 = 80.85 g/34.02 g/mol = 2.377 moles H2O2
For each mole of H2O2 you obtain 0.5 mole of O2 (see the equation).
moles O2 = 2.377 moles H2O2 (1 mole O2)/(2 moles H2O2) = 1.188 moles O2
Now, you need the temperature. If you are at STP (273 K, and 1.00 atm) then 1 mole of an ideal gas at STP has a volume of 22.4 L. Without temperature you are not really able to continue. I will assume you are at STP.
Volume O2 = 1.188 moles O2(22.4 L/mole) = 0.0530 L of O2.
which is 53 mL.
Answer:
2.11 * 10^3 molecules of phosphoric acid
Explanation:
Answer: An ionic bond is a bond that forms between ions with opposite charges.
Explanation:
A chemical bond formed by the transfer of electrons from one atom to another is called an ionic bond.
For example, sodium has electronic distribution as 2, 8, 1 and chlorine has electronic distribution as 2, 8, 7.
In order to attain stability, sodium needs to lose 1 electron and chlorine needs to gain one electron. Therefore, sodium will transfer its one valence electron (forming 
ion) to chlorine atom (forming 
ion) which leads to the formation of NaCl compound.
Thus, we can conclude that an ionic bond is a bond that forms between ions with opposite charges.
Plants, algae, and a group of bacteria called cyanobacteria are the only organisms capable of performing photosynthesis. They use light to manufacture their own food, they are called photoautotrophs (literally, “self-feeders using light”).
