Answer:
6
Explanation
every p sublevel holds up to 6 electrons
so the 4p sublevel must hold up to 6 electonsr
What's the big M? Molecular weight or mol?
Answer:
a) 213.3 mg/L
b) 62.61 mg/L
c) 0.0225 mg/L
Explanation:
Theoretical oxygen demand (ThOD)is essentially the amount of oxygen required for the complete degradation of a given compound into the final oxidized products
a) Given:
Concentration of acetic acid,
= 200 mg/L


Based on the reaction stoichiometry:
mass of
= 60 g
mass of
= 2(32) = 64 g

b) Given:
Concentration of ethanol,
= 30 mg/L


Based on the reaction stoichiometry:
mass of
= 46 g
mass of
= 3(32) = 96 g

c) Given:
Concentration of sucrose,
= 50 mg/L


Based on the reaction stoichiometry:
mass of
= 342 g
mass of
= 12(32) = 384 g

<span>Drill bits are attached to power drills to make holes. Drill bits are made of carbon-steel because they’re hard and resistant to corrosion. However, it is not only limited to carbon-steel. There are also other materials that are used for drill bits such as high speed steel, titanium coated steel and the like. The bodies and handles of power drills are made of polyethylene because they’re good insulators. </span>
