The moles of water that are produced from 373 moles of ammonia present in any chemical reaction is 746 moles.

<h3>What is the stoichiometry?</h3>

Stoichiometry of the reaction gives idea about the amount of entities present in any chemical reaction before and after the reaction.

Given chemical reaction is:

3Al + 3NH₄ClO₄ → Al₂O₃ + AlCl₃ + 3NO + 6H₂O

From the stoichiometry of the reaction it is clear that:

3 moles of Al = produces 6 moles of H₂O

373 moles of Al = produces 6/3×373 = 746 moles of H₂O

Hence required moles of water is 746 moles.

Marina86 [1]

Answer:

In the other of increasing wavelength we arrange as

<em>X-rays</em>

<em>ultraviolet</em>

<em>green light</em>

<em>red light</em>

<em>infrared</em>

<em>radio waves</em>

<em></em>

Explanation:

In the electromagnetic spectrum, wavelength decreases with increase in the energy of the electromagnetic wave. Since the e-m wave spectrum is arranged in the order of increasing energy (decreasing wavelength) as: Radio wave; infrared; visible light; ultraviolet; x-rays; gamma rays. Within the visible light, the green light has more energy than the red light. Therefore, the arrangement should be in the reverse direction of their increasing energy.

If a gas is initially at a pressure of 9 atm, a volume of 21 liters, and a temperature of 253 K, and then the pressure is raised
alex41 [277]

Answer:

15.04 mL

Explanation:

Using Ideal gas equation for same mole of gas as

\frac {{P_1}\times {V_1}}{T_1}=\frac {{P_2}\times {V_2}}{T_2}

Given ,  

V₁ = 21 L

V₂ = ?

P₁ = 9 atm

P₂ = 15 atm

T₁ = 253 K

T₂ = 302 K

Using above equation as:

\frac {{P_1}\times {V_1}}{T_1}=\frac {{P_2}\times {V_2}}{T_2}

\frac {{9}\times {21}}{253}=\frac {{15}\times {V_2}}{302}

Solving for V₂ , we get:

<u>V₂ = 15.04 mL</u>
