Answer:
There are a number of possibilities for the answer to this question, so I will address a few only:
Explanation:
1. Many ionic substances will dissolve completely in water to form an aqueous solution of cations and anions; this solution will conduct electricity.
2. The substance will have a slightly lower melting point than a mid-level covalent network solid.
3. The substance will certainly not conduct electricity as a solid.
Answer: Absorption. The transfer of energy carried by light waves to particles of matter.
Explanation:
mass Hydrogen=9.376 g
<h3>Further explanation
</h3>
Reaction
2H₂+O₂⇒2H₂O
mass H₂ = 10 g
mol H₂(MW=2 g/mol) :
10 : 2 = 5
mass O₂=5 g
mol O₂(MW=32 g/mol) :
5 : 32 = 0.156
O₂ limiting reactant
mol H₂: mol O₂ = 2: 1, so mol H₂ :
2 x 0.156 = 0.312
mol H₂ :
5 - 0.132 =4.688
mass of H₂ :
4.688 x 2 =9.376 g
