Answer:
The Rutherford atomic model stated that an atom is mostly an empty space that consist of nucleus and electrons, where nucleus is positively charged and electrons are negatively charged.
<em>But Rutherford atomic model missed to add the quantum mechanics or energy level for electrons. Rutherford was unable to make understand the planetary movement of electrons around nucleus and later Bohr's model explained it.</em>
Hence, Rutherford's model of the atom missed to explain the planetary movement of electrons around nucleus.
23 because it is the answer
<u>Given information:</u>
Mass of H2 = 2 g
Mass of O2 = 32 g
<u>To determine:</u>
Mass of H2O2 produced
<u>Explanation:</u>
The reaction between H2 and O2 can be given as:
H2 + O2 → H2O2
Based on the reaction stoichiometry:
1 mole of H2 reacts with 1 mole of O2 to form 1 mole of H2O2
# moles of H2 = mass of H2 / molar mass of H2 = 2 g/ 2 g.mol-1 = 1 mole
# moles of O2 = mass of O2/ molar mass of O2 = 32 g/ 32 g.mol-1 = 1 mole
Hence for the given reactant conditions, moles of H2O2 produced = 1
Mass of H2O2 = moles of H2O2 * molar mass H2O2 = 1 mole * 34 g.mole-1 = 34 g
<u>Ans</u>: 34 g of H2O2 is produced in this reaction
It is basic because of the fact that it has a strong base which is KOH and a weak acid HCN and the strong base causes it to remain more basic.
