Chemistry
1 answer:
Pie3 years ago
8 0

Answer:

a)goes down regardless of whether the reaction is exothermic or endothermic

Explanation:

The activation energy is the minimum amount of energy required for a chemical reaction to commence. As this increases, the reaction will become slower because it must overcome this barrier.

arsen [322]

The Elephant Maximus is the species that was introduced and later became extinct on Maguindanao.

Extinction occurs as all members of a species die, and therefore the species disappears. This includes complete extinction or extinction of the species in a specific zone.

In the case of the Elephant Maximus, which is known as the Asian Elephant, this species became extinct in a region known as Maguindanao in the Philippines.

This partial extinction occurred as the elephants from this zone were taken to Sabah in Malaysia from the 13th century to the 16th century. This occurred because the Sultans of this region considered this elephant to be a valuable and even sacred animal.

The reaction of NH3 and O2 forms NO and water. The NO can be used to convert P4 to P4O6, forming N2 in the process. The P4O6 can
posledela

Answer : The mass of PH_3 produced from the reaction is, 0.651 grams.

Explanation :

The chemical reactions used are:

(1) 4NH_3+5O_2\rightarrow 4NO+6H_2O

(2) 6NO+P_4\rightarrow P_4O_6+3N_2

(3) P_4O_6+6H_2O\rightarrow 4H_3PO_4

(4) 4H_3PO_4\rightarrow PH_3+3H_3PO_4

First we have to calculate the moles of NH_3

\text{Moles of }NH_3=\frac{\text{Mass of }NH_3}{\text{Molar mass of }NH_3}

Molar mass of NH_3 = 17 g/mol

\text{Moles of }NH_3=\frac{1.95g}{17g/mol}=0.115mol

Now we have to calculate the moles of NO

From the balanced chemical reaction 1, we conclude that:

As, 4 moles of NH_3 react to give 4 moles of NO

So, 0.115 moles of NH_3 react to give 0.115 moles of NO

Now we have to calculate the moles of P_4O_6

From the balanced chemical reaction 2, we conclude that:

As, 6 moles of NO react to give 1 moles of P_4O_6

So, 0.115 moles of NO react to give \frac{0.115}{6}=0.0192 moles of P_4O_6

Now we have to calculate the moles of H_3PO_4

From the balanced chemical reaction 3, we conclude that:

As, 1 moles of P_4O_6 react to give 4 moles of H_3PO_4

So, 0.0192 moles of P_4O_6 react to give 0.0192\times 4=0.0768 moles of H_3PO_4

Now we have to calculate the moles of PH_3

From the balanced chemical reaction 4, we conclude that:

As, 4 moles of H_3PO_4 react to give 1 moles of PH_3

So, 0.0768 moles of H_3PO_4 react to give \frac{0.0768}{4}=0.0192 moles of PH_3

Now we have to calculate the mass of PH_3

\text{ Mass of }PH_3=\text{ Moles of }PH_3\times \text{ Molar mass of }PH_3

Molar mass of PH_3 = 33.9 g/mole

\text{ Mass of }PH_3=(0.0192moles)\times (33.9g/mole)=0.651g

Therefore, the mass of PH_3 produced from the reaction is, 0.651 grams.
