The proposed mechanism for the reaction ClO-(aq) + I-(aq) --&gt; IO-(aq) + Cl-(aq) is
vaieri [72.5K]

Answer:

1 ClO-(aq) + 1 I-(aq) ---> 1 Cl -(aq) + 1 IO-(aq).

Explanation:

1. ClO-(aq) + H2O(l) <=> HClO(aq) + OH-(aq)

2. I-(aq) + HClO(aq) <=> HIO(aq) + Cl-(aq)

3. OH-(aq) + HIO(aq) => H2O(l) + IO-(aq)

Adding all the 3 equations together gives and it gives:

ClO-(aq) + H2O(l) + I-(aq) + HClO(aq) + OH -(aq) + HIO(aq)

---> HClO(aq) + OH-(aq) + HIO(aq) + Cl -(aq) + H2O(l) + IO-(aq)

Deleting the same species on both sides of the equation gives:

1 ClO-(aq) + 1 I-(aq) ---> 1 Cl -(aq) + 1 IO-(aq)

The overall equation:

1 ClO-(aq) + 1 I-(aq) ---> 1 Cl -(aq) + 1 IO-(aq)

How much heat does it take to raise 100g of aluminum (c= .9 J/gC) from 12.5C to 31C?
zlopas [31]

Answer:

When two substances having different temperatures are introduced or kept together, heat energy, Q, flows from a substance at higher temperature to a substance at lower temperature. Also, heat continues to be transferred until their temperatures are equalized, at which point the substances are in thermal equilibrium. In a closed system, the amount of energy lost is equal to but opposite the amount of energy gained.

STP refers to:
Greeley [361]
The  STP is  Standard temperature and pressure. 

Standard temperature is defined as zero degrees Celsius (0° C)

Standard pressure supports 760 millimeters in a mercurial barometer (760 mmHg)

we have that 
760 mmHg= 1 atm

therefore
the answer is  
0 deg C and 1 atm.
