<span>Answer: Once these values are put into the equation delta Q=mc delta T it will give you the same value for Q (change in energy) if the same fuel is used 50mL will mean it gets heated quicker making the experiment quicker 200mL would take longer to heat for the same change in temperature causing a longer experiment.</span>

How many moles of ammonium nitrate will be produced 110.0g of ammonium carbonate
marshall27 [118]

Answer:

                     2.288 Moles of NH₄NO₃

Explanation:

The Balance chemical equation is as follow:

                  (NH₄)₂CO₃ + 2 HNO₃  →  2 NH₄NO₃ + H₂O + CO₂

To solve this problem we will do following steps:

Finding moles of Ammonium Carbonate:

As we know,

                        Moles  =  Mass / M.Mass

So,

                        Moles  =  110 g  /  96.08 g/mol

                        Moles  =  1.144 moles

Calculating moles of Ammonium Nitrate:

According to balance chemical equation;

                      1 mole of (NH₄)₂CO₃ produces  =  2 moles of NH₄NO₃

So,

          1.144 moles of (NH₄)₂CO₃ will produce  =  X moles of NH₄NO₃

Solving for X,

                     X =  2 moles × 1.144 moles ÷ 1 mole

                     X  =  2.288 moles of NH₄NO₃

How do you think the vertical temperature
WARRIOR [948]

thermal conduction and convection processes we explain the temperature profile: warmer at the bottom and colder at the top

Temperature is a measure of the internal energy of molecules.

When the pot is on the burner, the lower part of the pot acquires energy from the flame, this energy increases the temperature of the metal that is in contact with the liquid from the bottom, by a process of thermal conduction, while the liquid in the top is kept at the same temperature.

As time progresses, the hotter lower liquid, for which it has a lower with the metal bottom heats up by conduction. density, conscientiously rise and a transfer of heat is created by convection, which raises the temperature of the hot liquid and makes the liquid fall that is colder from the upper part than at the coming into contact

This cycle is repeated heating all the liquid. But the liquid with the liquid in the lower part always at a higher temperature than the liquid in the upper part, the process stops when the liquid in the lower part reaches the boiling point, than the passage from liquid to gas, during which the temperature remains constant.

With the thermal conduction and convection processes we explain the temperature profile: warmer at the bottom and colder at the top.
