A cell consists of a gold wire and a saturated calomel electrode (S.C.E.) in a 0.130 M AuNO 3 solution at 25 °C. The gold wire i

s connected to the positive end of a potentiometer, and the S.C.E. is connected to the negative end of the potentiometer. What is the half‑reaction that occurs at the Au electrode? Include physical states.

Answer:

The half reaction occurring at this electrode will be given as:

Au^++e^-\rightarrow Au

Explanation:

In electrochemical cell reduction occurs at anode.

But the gold wire is connected to the positive terminal of the battery which means that gold wire will act as a cathode nad reduction will take place

The half reaction occurring at this electrode will be given as:

Au^++e^-\rightarrow Au

Given 20.0 g of (NH4)3 PO3 how many moles is this? How many formula units is it? How many hydrogen atoms are present?
Setler79 [48]

Answer:

no of moles = (mass) ÷ molar mass

you get the molar mass from the periodic table

n = 20.0g ÷ ( 149.09 g/mol )

= 0.134 mol

number of formula units = number of moles × (6.022×10^23)

= 8.07×10^22 units

number of hydrogen atoms in (NH4)3 PO3 = 12 × number of formula units

= 9.68×10^23 hydrogen atoms

11. What is the concentration (in M) of an ammonia (NH3) solution if 12.23 grams of ammonia are
photoshop1234 [79]

Answer:  1.284M NH3

Explanation:  (12.23 grams)/(17.0 gramms/mole) = 0.7191 moles

Dissolved in 560.0 ml (=0.5600L)

(0.7191 moles)/(0.560L) = 1.284M  (4 sig figs)
