BartSMP [9]2 years ago
6 0

Answer:

An acid

Explanation:

» The reaction of any hydrogen ion or hydroxonium ion with a base results into an acidic solution.

For hydrogen ions:

{ \rm{H {}^{ + }_{(aq)} +  Cl {}^{ - } _{(aq)} \:  \dashrightarrow \: HCl _{(aq)}  }}

For hydroxonium ions:

{ \rm{H _{3} O {}^{ + } _{(aq)}  +Cl {}^{ - }  _{(aq)} \:  \dashrightarrow \:HCl _{(aq)}   +  H _{2} O _{(l)}}}

How many atoms of phosphorus are in 4.5 grams of tetraphosphorus decoxide?
Alexxx [7]

Answer:

In 4.5 grams of tetraphosphorus decoxide we have 3.85 * 10^22  phosphorus atoms

Explanation:

Step 1: Data given

tetraphosphorus decoxide = P4O10

Molar mass of P4O10 = 283.89 g/mol

Mass of P4O10 = 4.5 grams

Number of Avogadro = 6.022 * 10^23 / mol

Step 2: Calculate moles of P4O10

Moles P4O10 = mass P4O10 / molar mass P4O10

Moles P4O10 = 4.5 grams / 283.89 g/mol

Moles = 0.016 moles

Step 3: Calculate moles of P

For 1 mol P4O10 we have 4 moles of phosphorus

For 0.016 moles P4O10 we have 4*0.016 = 0.064 moles P

Step 4: Calculate number of P atoms

Number of P atoms = moles P * number of Avogadro

Number of P atoms = 0.064 moles * 6.022*10^23

Number of P atoms = 3.85 * 10^22 atoms

In 4.5 grams of tetraphosphorus decoxide we have 3.85 * 10^22  phosphorus atoms

Assuming you have 6.24 x 1014 electrons and the surface area of the pail is 0.2 m2, what is the charge density (C/m2)?
pentagon [3]

Answer:

σ = 4.998 E-4 C/m²

Explanation:

  • 1 Coulomb (C) ≡ 6.241509 E18 electrons (e)

∴ # elect = 6.24 E14 elect

charge (Q):

⇒ Q = (6.24 E14 elect)/( 1 C /6.241509 E18 elect) = 9.998 E-5 C

charge density (σ):

  • σ = Q/S

∴ surface area (S) = 0.2 m²

⇒ σ = ( 9.998 E-5 C ) / ( 0.2 m²)

⇒ σ = 4.998 E-4 C/m²
