Answer:

Photosynthesis is Endothermic reaction.

Explanation:

Photosynthesis:

It is the process in which in the presence of sun light and chlorophyll by using carbon dioxide and water plants produce the oxygen and glucose.

Word equation:

Carbon dioxide + water + energy →   glucose + oxygen

Chemical equation:

6H₂O + 6CO₂ + energy  →   C₆H₁₂O₆ + 6O₂

it is known from balanced chemical equation that 6 moles of carbon dioxide react with the six moles of water and created one mole of glucose and six mole of oxygen.

water is supplied through the roots, carbon dioxide collected through stomata and sun light is capture  by chloroplast.

The energy required for this reaction is taken from sun.

While other given reactions are exothermic reactions.

2)

Answer:

Exothermic

Explanation:

Exothermic reaction:

The type of reactions in which energy is released are called exothermic reactions.

In this type of reaction energy needed to break the bonds are less than the energy released during the bond formation.

For example:

When acid and base are react heat is produced. The flask in which reaction is proceed is warm when we touch it. It indicate the exothermic reaction.

Chemical equation:

NaOH + HCl → NaCl + H₂O + heat

3)

Answer:

Heat is released

Explanation:

Exothermic reaction:

The type of reactions in which energy is released are called exothermic reactions.

In this type of reaction energy needed to break the bonds are less than the energy released during the bond formation.

For example:

Chemical equation:

C + O₂   →  CO₂

ΔH = -393 Kj/mol

it can be written as,

C + O₂   →  CO₂ + 393 Kj/mol

How many grams of i2 are needed to react with 30.1 g of n2h4?
Nina [5.8K]

The reaction is,

H2S + I2 --------------> 2 HI +S

Molar weight of H2S = 34 g per mol

Molar weight of HI =128 g per mol

Molar weight of I2 =254 g per mol

Moles of H2S in 49.2 g  = 49.2 /34 mol = 1.447 mol

So according to stoichiometry of the reaction, number of I2 mols needed                      

                                  = 1.447 mol

The mass of I2  needed = 1.447 mol x 254 g
