Chemistry
1 answer:
zhenek [66]2 years ago
8 0

Answer:

see explanation

Explanation:

#Atoms = (mass/atomic wt) x 6.02 x 10²³

  • mass is grams
  • atomic weight is grams/mole
  • 6.02 x 10²³ is atoms/mole

Consider this reaction: 2al(s) + 3 cucl2(aq) → 2alcl3(aq) + 3 cu(s) if the concentration of cucl2 drops from 1.000 m to 0.655 m
kirza4 [7]
The average rate of reaction over a given interval can be calculated by taking the difference of concentration on a particular given reactant, and dividing it by the total time. In this case, (1.00 M - 0.655 M)/30 s = 0.0115 M/s, or 0.0115 mol/L-s, and this is the final rate of reaction.

Write a balanced half-reaction describing the reduction of gaseous dichlorine to aqueous chloride anions.
Annette [7]

Answer:- Cl_2(g)+2e^-\rightarrow 2Cl^-(aq)

Explanations:- In reduction the electrons are accepted and so they are written on the reactant side. When an atom accepts electrons then it forms anion. Chlorine has 7 valence electrons and it needs one more electron to complete it's octet. Since, dichlorine has two Cl atoms and each Cl atom needs one more electron to complete it's octet, two electrons are accepted by dichorine to make aqueous chloride ion. For balancing the equation, there would be two chloride ions as the reactant side has two chlorine atoms.

Taking logarithms and antilogarithms is necessary to solve many chemistry problems. For practice,
shepuryov [24]

The values of N, log N and ln N are all worked out below.

We have the number N as 8.99

hence;

1) lnN = ln(8.99) = 2.196

log N = log (8.99) = 0.954

2) If we have ln N as 3.949

N = e^3.949 = 51.88

So;

log N = log (51.88) = 1.715

3) log N = 0.134

N = Antilog (0.134 ) = 1.36

ln N = ln (1.36) = 0.307
