The equilibrium constant, represented as a variable K, is the ratio of the concentration of the products to the reactants which are raised respectively to their stoichiometric coefficients. Note that only substances in the aqueous phases are accounted. From the reaction given, K is equal to

<em>K = [Sn²⁺]³/[Fe³⁺]²</em>

Once you know the equilibrium concentration of Sn²⁺ and Fe³⁺ in molarity, just substitute them into the equation to solve for K.

Tju [1.3M]

The smallest unit of an element that still retains the distinctive behavior of that element is an: atom

<h3 />

A single atom of an element keep its distinctive behavior, that's because the atom is the smallest unit of the composition of a chemical element

<h3>What is an atom?</h3>

The atom is the smallest part of the composition of matter, it is indivisible and is composed of a nucleus that has protons and neutrons, and around the nucleus there are the electrons.

4. A student started with a 0.032 g sample of copper which he took through the series of reactions described in this experiment.
Elodia [21]

Answer:

Y=48.6\%

Explanation:

Hello,

In this case, we can consider the following chemical reaction for the oxidation of copper which only occurs at high temperatures:

2Cu+O_2\rightarrow 2CuO

In such a way, for 0.032 grams of copper, the following grams of copper (II) oxide (black product) are yielded:

m_{CuO}=0.032gCu*\frac{1molCu}{63.546gCu} *\frac{2molCuO}{2molCu}*\frac{79.546gCuO}{1molCuO}  =0.078gCuO

Therefore, the percent yield is:

Y=\frac{0.038g}{0.078g}*100\%\\ \\Y=48.6\%

Best regards.

A certain substance, X, has a triple-point temperature of 20°C at a pressure of 2.0 atm.
nikitadnepr [17]

Answer: The statement which could possibly not be true is C -" Liquid X can exist as a stable phase at 25°C, 1atm."

Explanation:

Triple point is the point where a substance co-exist as solid liquid and gas. At any point other than the triple point, the substance exist as a single phase substance.

As shown in the diagram, Liquid cannot exist as a stable phase at 1atm( below the the triple point pressure of 2atm) as the liquid can only exist beyond the pressure of triple point.
