Answer:
All unauthorized experiments are prohibited. You are allowed to enter the chemical preparation/storage area any time you need to get an item. Laboratory aprons should be worn during all lab activities. It's okay to pick up broken with our bare hand as long as the glass is placed in the trash.
Explanation:
Answer:
Reduction involves a half-reaction in which a chemical species decreases its oxidation number, usually by gaining electrons. The other half of the reaction involves oxidation, in which electrons are lost. Together, reduction and oxidation form redox reactions (reduction-oxidation = redox).

Answer:
Molecular formula = P₄O₁₀
Explanation:
Given data:
Empirical formula of compound = P₂O₅
Molar mass of compound = 426 g/mol
Molecular formula = ?
Solution:
Molecular formula:
Molecular formula = n (empirical formula)
n = molar mass of compound / empirical formula mass
Empirical formula mass= P₂O₅ = 283.89 g/mol
n = 426 g/mol / 283.89 g/mol
n = 2
Molecular formula = n (empirical formula)
Molecular formula = 2 (P₂O₅ )
Molecular formula = P₄O₁₀
