The yield of ammonia rises as reaction pressure is raised. The yield of ammonia in the reaction actually declines as reaction temperature rises.
<h3 /><h3>What is ammonia ?</h3>
Ammonia, the simplest pnictogen hydride and a stable binary hydride, is a colorless gas with a strong, pungent odor. It contributes considerably to the nutritional demands of terrestrial creatures by serving as a precursor to 45 percent of the world's food and fertilizers. Biologically, it is a common nitrogenous waste, especially among aquatic animals. About 70% of ammonia is used to create fertilizers, including urea and diammonium phosphate, in a variety of shapes and compositions. Additionally, pure ammonia is sprayed straight onto the ground.

Answer:
872093.02moles
Explanation:
Given parameters:
Number of atoms of Sucrose = 5.25 x 10²⁹atoms
Unknown:
Number of moles = ?
Solution:
To solve this problem, we must understand that a mole of any substance contains the Avogadro's number of particles.
6.02 x 10²³ atoms makes up 1 mole of an atom
5.25 x 10²⁹ atoms will contain = = 872093.02moles
Answer:
The enthalpy change during the reaction is -7020.09 kJ/mole.
Explanation:
First we have to calculate the heat gained by the calorimeter.
where,
q = heat gained = ?
c = specific heat =
= final temperature =
= initial temperature =
Now put all the given values in the above formula, we get:
The heat gained by water present in calorimeter. = q'
where,
q' = heat gained = ?
m = mass of water =
c' = specific heat of water =
= final temperature =
= initial temperature =
q ' = 12,060.38 J
Now we have to calculate the enthalpy change during the reaction.
where,
= enthalpy change = ?
Q = heat gained = -(q+q') = -(2,485.25 J + 12,060.38 J)= -14,545.63 J
Q = -14.54563 kJ
n = number of moles fructose =
Therefore, the enthalpy change during the reaction is -7020.09 kJ/mole.
Answer:
The correct option is 9
Explanation:
The easiest way to balance any combustion equation is to first write the general form. In a combustion reaction the products are always carbon dioxide (CO2) and water (H2O) and the reactants are the organic material plus oxygen (O2).
General Form:
C6H12 + O2 --> CO2 + H2O
Now start by balancing the carbon atoms:
six carbons on the left so you need 6 on the right.
C6H12 + O2 ---> 6 CO2 + H2O
Next balance the hydrogen atoms:
12 on the left, so you need 12 on the right.
C6H12 + O2 --> 6CO2 + 6H2O
Now count the number of oxygen on the right = 12 + 6= 18
Divide the number on the right by 2 to get the number needed on the left. 18/2 = 9
