Study the reaction. NO(g) ⇌ 12N2(g) + 12O2(g) ΔH = −90.3 kJ Which statement about the reaction is correct? A) The reverse reacti
lozanna [386]

Answer:

The forward reaction is an exothermic reaction.

Explanation:

An exothermic reaction is one in which energy is released, usually in the form of heat hence the enthalpy of the reaction is negative. When a reaction exothermic, the energy of the reactants is greater than the energy of the products hence the excess energy is given out as heat. The reactants lie at a higher energy level in the reaction profile compared to the products.

When we look at the reaction given in the question, NO(g) ⇌ 12N2(g) + 12O2(g) ΔH = −90.3 kJ , we can easily see from the thermochemical reaction that the forward reaction is exothermic, energy is released by the reaction system as evidenced by the negative enthalpy of reaction.

Write the reaction equation and equilibrium equation for dopamine
elena-s [515]

Answer:

The see explanation

Explanation:

In this case, we have an <u>"amine"</u> group in the dopamine structure. So, the dopamine will act as a <u>"base"</u>. A base is a substance that has the ability to <u>accept hydrogens</u>, therefore, the NH_2 will take hydrogen from the water molecule. Additionally, the water will produce the OH^- ion and the NH_2 will be converted into NH^+_3.

See figure 1

I hope it helps!

How can you tell whether a fat contains primarily saturated or unsaturated fatty acids?
Elden [556K]
Hello!

Oils that remain a clear color in the refrigerator are unsaturated. 

Unsaturated fats are those with double bonds in their fatty acid chain. These are known as being "healthier" than the saturated fats, which don't have any double bonds. Unsaturated fats, when put into the refrigerator are harder to become solid and change color than saturated fats because the double bonds make the structure to have less intermolecular interactions by steric hindrance and thus a lower melting point. 

Have a nice day!

Why can water dissolve many ionic compounds
ludmilkaskok [199]
To dissolve an ionic compound, the water molecules must be able to stabilize the ions that result from breaking the ionic bond. Water is a polar molecule. It has a permanent dipole. ... The negative ions have several water molecules around them, all with their H atoms close to the negative ion
