Answer:
Aluminum is ideal for aircraft manufacture because it's lightweight and strong. Aluminum is roughly a third the weight of steel, allowing an aircraft to carry more weight and or become more fuel efficient. Furthermore, aluminum's high resistance to corrosion ensures the safety of the aircraft and its passengers.
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: The lower temperature reduces molecule speeds, reducing the number of effective collisions.
Explanation:
Covalent bonds in solution, hydrogen bonds in solution, ionic bonds in solids, nonpolar covalent bonds in solids- the weakest bond is hydrogen bond.
What is a chemical bond?
A chemical bond is a strong bond that can be formed between atoms, ions, or molecules to create chemical compounds. In covalent bonds, the electrons are shared, whereas in ionic bonds, the electrostatic attraction of two ions with opposing charges forms the link. Strong bonds, also known as primary bonds, include covalent, ionic, and metallic ties. Weak bonds, also known as secondary bonds, include dipole-dipole interactions, the London dispersion force, and hydrogen bonds.
Since there is no necessity for an electron exchange during formation, the hydrogen bond is weak. As a result, it is simpler to break apart a hydrogen connection between two molecules.
