Be sure to answer all parts.The equilibrium constant (Kc) for the formation of nitrosyl chloride, an orange-yellow compound, fro

m nitric oxide and molecular chlorine 2NO(g) + Cl2(g) ⇌ 2NOCl(g) is 1 × 107 at a certain temperature. In an experiment, 4.40 × 10−2 mole of NO, 1.80 × 10−3 mole of Cl2, and 9.50 moles of NACl are mixed in a 2.60−L flask. What is Qc for the experiment

Explanation:

Since, the given reaction is as follows.

       2NO(g) + Cl_{2} \rightleftharpoons 2NOCl

Expression for Q_{c} of this reaction is as follows.

       Q_{c} = \frac{[NOCl]^{2}}{[NO]^{2}[Cl_{2}]}

Putting the given values into the above formula as follows.

       Q_{c} = \frac{[NOCl]^{2}}{[NO]^{2}[Cl_{2}]}

               = \frac{(9.50)^{2}}{(4.40 \times 10^{-2})^{2} \times (1.80 \times 10^{-3})}

               = \frac{90.25}{34.848 \times 10^{-7}}

              = 2.59 \times 10^{-7}

Thus, we can conclude that Q_{c} for the experiment is 2.59 \times 10^{-7}.

2. What is the mass of 5.33 x 10 moles of aluminum hydroxide?​
bearhunter [10]
<h3>Answer:</h3><h3>1865.5g</h3><h3>Explanation:</h3><h3 /><h2> first the chemical formular for ammonium hydroxide is NH4OH</h2><h3>its molarmass is given as N=14H=1O=16 </h3><h3> so we have 14 +1(2) +16+1 =35</h3><h2>also no of moles = mass / molarmass</h2><h3> we have 5.33×10 = mass/35 </h3><h2>therefore mass = 35 ×5.33×10 = 1865.5g</h2>

Elements that have five electrons in the highest-energy p sublevel in their ground state are called what?
wolverine [178]
Elements that have six electrons in the highest-energy p sublevel in their ground state are called the noble gases or inert gases. The six noble gases that occur naturally are helium (He), neon (Ne), argon (Ar), krypton (Kr), xenon (Xe), and the radioactive radon (Rn).

Is a diamond a homogeneous or heterogeneous mixture or a substance
DerKrebs [107]

Answer:

heterogeneous

Explanation:

It's a heterogeneous mixture. Diamond is made of just one element: carbon. Each carbon atom in diamond is connected to four other carbon atoms, in a crystal that extends on and on. There are other forms of pure carbon where the atoms are bonded differently, notably charcoal and graphite.
