Answer: The most commonly cited impact is deforestation, i.e., the clearance of forest or woodland. At a small spatial scale this may indeed be the case but on a larger landscape scale charcoal production most frequently results only in forest degradation. The contribution of charcoal to deforestation in the tropics is less than 7%. Charcoal production most frequently results in forest degradation. Most charcoal areas have the potential for rapid forest recovery.
Explanation:
<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
Answer:
1. They debated about many things.
2. Greek philosophers debated about things. They did not have a scientific/experiment based approach to studying nature. They did not have tools.
3. Democritus
4. Democritus had the basic idea of atoms, even though he had no experimental evidence to support his thinking.
5. taught that there were substances called atoms and that these atoms made up all material things. The atoms were unchangeable, indestructible, and always existed.
