Bingel [31]

Answer:

Hexose category and ketohexose category

Explanation:

The classification of the Carbohydrate tagatose by carbonyl group is that it is a monosaccharide and has a hexose structure hence it belongs to the Hexose category

Based on the number of carbon atoms the structure has a ketofunctionality hence it is classified under the ketohexose category

Attached below is the remaining part of the solution

The reaction for the synthesis of ammonia N2(g) + 3 H2(g) → 2 NH3(g) is exothermic. Increasing the temperature applied to the sy
igomit [66]

Answer:

The correct statements are (II) and (III).

Explanation:

Any change in the equilibrium is studied on the basis of Le-Chatelier's principle.

This principle states that if there is any change in the variables of the reaction, the equilibrium will shift in the direction to minimize the effect.

For the given equation:

N_2(g)+3H_2(g)\leftrightharpoons 2NH_3(g)

This is a type of exothermic reaction because heat is released in the reaction.

On increasing the temperature

If the temperature is increased, so according to the Le-Chatlier's principle , the equilibrium will shift in the direction where decrease in temperature occurs. As, this is an exothermic reaction, forward reaction will increase the temperature. Hence, the equilibrium will shift in the left direction.

And by moving to left side amount of ammonia will decrease accompanied by the change in the value of an equilibrium constant.

What does forward bias on a diode mean?
KiRa [710]

Answer:

Explanation: When the p-type side of the diode is connected to a higher potential than the n-type side, the diode is then forward biased, because it enhances the capability of the diode to conduct forward current.
