How much heat is absorbed by 100 mL of a dilute solution of NH4NO3 as it changes its temp from 25.3 Celsius to 22.4 Celsius?
Katb515
q=mc(Tf-Ti)
assume 100 ml = 100 g
c=4.184 J/Kg
q=(100g)(4.184J/Kg)(22.4-25.3)
q=-1213.36J

What is the chemical formula of ammonium trioxonitrate V?
Nh4no3
The reaction of NH4NO3 with water to form an acidic solution is called a oxidation b hydrolysis C electrolysis D reduction?
B
How does cold compress work?
A Cold Compress typically consists of liquid water or capsules of water (H2O) with a separated, easily puncturable capsule or packet of ammonium nitrate (NH4NO3). When the packet or capsule of NH4NO3 is punctured and allowed to mix thoroughly with the H20, the resulting solution undergoes an rapid endothermic reaction. An endothermic reaction takes place when heat energy is absorbed from outside sources, in this case, causing the surrounding material to become colder then it's ambient temperature.-A. Wicht
What is the symbol for Ammonia solution?
Ammonium nitrite is NH4NO2 Ammonium nitrate is NH4NO3
What is the boiling point of a 2.86 m solution of ammonium nitrate NH4NO3 Assume that the solvent is water which has a Kb of 0.51ºC m and a boiling point of 100.0ºC?
103.6ºC
How many milliliters of 0.580 M NH4NO3 solution musr be diluted with water to produce 500.00 mL of a solution of 0.029 M?
10
What is the chemical formula of ammonium trioxonitrate V?
Nh4no3
How many grams of NH4NO3 would be required to prepare 0.500 L of a solution that is 0.450 M in NH4NO3(aq)?
NH4NO3's molar mass = 80.0gMolarity = moles of solute / liters of solution0.450 M = X / 0.500 LX = .225 molesNow we must convert X to grams because it is currently in moles.(.225 moles) / 1 * ( 80.0 grams ) / 1 mole =18 grams of NH4NO3
How much heat is absorbed by 100 mL of a dilute slution of NH4NO3 as it changes its temperature from 25.3 to 22.4?
Ammonium nitrate has a specific heat of 4.184 Joules per kilogram. Given that q = mc(Tf - Ti), m = 100 grams, and q = -1213.36 Joules
What is a good hypothesis for endothermic reactions?
Dissolve different amount of NH4NO3 in water and then follow the changes in temperature in each case.
The reaction of NH4NO3 with water to form an acidic solution is called a oxidation b hydrolysis C electrolysis D reduction?
B
Dissolution for NH4NO3?
NH4NO3 + H2O --> NH4+ + NO3- That's the dissolution. (:
What is the universe BA and NH4NO3?
NH4NO3 is the chemical formula of ammonium nitrate.

NH4NO2 and NH4CN which has a higher pH?
A solution of NH4CN will generally have a higher pH. It is a mildly basic salt while NH4NO3 is mildly acidic.
Why dissolving Ammonium nitrate(NH4NO3) in water is an endothermic although the temperature of the solution decreases?
The energy needed to support the endothermic reaction is supplied by the solution; thus the solution temperaturedecreases.If the reaction were exothermic, the solution temperature would increase.
What is the symbol for Ammonia solution?
Ammonium nitrite is NH4NO2 Ammonium nitrate is NH4NO3
