Answer:
1.125 x 10⁻³.
Explanation:
- For the reaction: <em>2NO(g) + Cl₂(g) → 2NOCl(g).</em>
<em>Kc = [NOCl]²/[NO]²[Cl₂],</em>
Where, [NOCl], [NO], and [Cl₂] is the equilibrium concentration of NOCl, NO, and Cl₂.
∵ Initial concentration of NO and Cl₂ = 0.50 M.
<em>And the equilibrium concentration of NOCl = 0.30 M.</em>
<em />
∴ The equilibrium concentration of NO, and Cl₂: [NO] = [Cl₂] = 0.50 M - 0.30 M = 0.20 M.
<em>∴ Kc = [NOCl]²/[NO]²[Cl₂]</em> = [0.30]²/[0.20]²[0.20] = <em>1.125 x 10⁻³.</em>

An oil water separator (OWS) is a piece of equipment used to separate oil and water mixtures into their separate components. There are many different types of oil-water separator
<span>Errors can come from various sources: the obtainer of the data, the measuring instrument, the setting and etc. Errors are what makes your measurement invalid and unreliable. There are two types of error which is called the systematic error and the random error. Each error has different sources. Words that were mentioned –invalid and unreliable are very important key aspects to determine that your measure is truly accurate and consistent. Some would recommend using the mean method, doing three trials in measuring and getting their mean, in response to this problem.</span>
The gram-formula mass of citric acid is 3(1)+6(12)+5(1)+16(7)=192 g/mol.
This means that in 13.00 grams of citric acid, there are 13.00/192 = 0.067 moles.
From the equation, we know that for every 1 mole of citric acid that is consumed, 3 moles of carbon dioxide are produced.
This means that there are 3(0.067)=0.203 moles.
Since the gram-formula mass of carbon dioxide is 12+2(16)=44 g/mol, meaning it has a mass of 0.203(44)=8.93 g
