Osazones<span> are a class of carbohydrate derivatives found in organic chemistry formed when sugars are reacted with excess of phenylhydrazine. The famous German chemist Emil Fischer developed and used the reaction to identify sugars whose stereochemistry differed by only one chiral carbon</span>
Answer:
The heat produced by this reaction is 2887J
Explanation:
The reaction of HCl with NaOH occurs as follows:
HCl + NaOH → H2O + NaCl + ΔH
<em>Where ΔH is released heat due the reaction</em>

The equation of a coffee cup calorimeter is:
Q = C*m*ΔT
<em>Where Q is heat produced, </em>
<em>C is specific heat of the solution (4.18J/g°C), </em>
<em>m is mass of the solution (50mL + 50mL = 100mL = 100g -Because density is 1g/mL) </em>
<em>and ΔT is change in temperature (28.9°C - 22.0°C = 6.9°C)</em>
<em />
Replacing:
Q = 4.184J/g°C*100g*6.9°C
Q = 2887J
The heat produced by this reaction is 2887J

Answer:
759779.6 torr
Explanation:
Initial volume, V₁ = 4001 mL
Final volume, V₂ = 3002 mL
Initial pressure, P₁ = 750.1 atm
We need to find the final pressure at a constant temperature. Let it be P₂. 
We know that,
1 atm = 760 torr
So,
999.71 atm = 759779.6 torr
Hence, there will be 759779.6 torr pressure.
