Answer:
D.) Nitrogen and Hydrogen are very stable bonds compared to the bonds of ammonia.
Explanation:
For the reaction:
3H₂(g) + N₂(g) → 2NH₃(g)
The enthalpy change is ΔH = -92kJ
This enthalpy change is defined as the enthalpy of products - the enthalpy of reactants. As the enthalpy is <0, The enthalpy of products is <em>lower </em>than the enthalpy of reactants.
Also, it is possible to obtain the enthalpy change from the bond energies of products - bond energies of reactants, thus, The total bond energies of products are <em>lower</em> than the total bond energies of reactants.
The rate of the reaction couldn't be determined using ΔH.
As the bond energy of ammonia is lower than bonds of nitrogen and hydrogen, <em>D. Nitrogen and Hydrogen are very stable bonds compared to the bonds of ammonia.</em>

Answer:
oatmeal with raisins is a heterogeneous mixture. The raisins may be solid, but turn the bowl over and you will see the mixture as a whole most definitely acts like a liquid. Mud puddles are a heterogeneous mixture.
Explanation:
Sucrose, a disaccharide (consisting of two monosaccharides), is table sugar.
A digestive enzyme called sucrase catalyses the breakdown of sucrose into its component sugars, fructose and glucose. One type, sucrase-isomaltase, is secreted at the brush boundary of the small intestine. Invertase, a form of the sucrase enzyme that is more frequently found in plants, also hydrolyzes sucrose but does it in a different way.
<h3>What does sucrase break down into ?</h3>
Maltose is converted to glucose by maltase. Succrase and lactase, respectively, break down other disaccharides like sucrose and lactose. Sucrase and lactase are enzymes that break down sucrose (also known as "table sugar") and lactose (sometimes known as "milk sugar"), respectively, into glucose and fructose.
- Both the breakdown of maltose into glucose and the breakdown of sucrose into glucose and fructose are carried out by the enzyme's sucrase subunit.

Answer:
Explanation:
Many elements have one or more isotopes that are radioactive these are called radioisotopes their their nuclei are unstable so they break now or decay and emit radiation
