Answer : The limiting reactant is Cl_2 and the theoretical yield will be 86.45 grams.

Explanation : Given,

Moles of Ti = 0.483 mole

Moles of Cl_2 = 0.911 mole

Molar mass of TiCl_4 = 190 g/mole

First we have to calculate the limiting and excess reagent.

The given balanced chemical reaction is,

Ti+2Cl_2\rightarrow TiCl_4

From the balanced reaction we conclude that

As, 2 moles of Cl_2 react with 1 mole of Ti

So, 0.911 moles of Cl_2 react with \frac{0.911}{2}=0.455 moles of Ti

From this we conclude that, Ti is an excess reagent because the given moles are greater than the required moles and Cl_2 is a limiting reagent and it limits the formation of product.

Now we have to calculate the moles of TiCl_4.

As, 2 moles of Cl_2 react to give 1 moles of TiCl_4

So, 0.911 moles of Cl_2 react to give \frac{0.911}{2}=0.455 moles of TiCl_4

Now we have to calculate the mass of TiCl_4.

\text{Mass of }TiCl_4=\text{Moles of }TiCl_4\times \text{Molar mass of }TiCl_4

\text{Mass of }TiCl_4=(0.455mole)\times (190g/mole)=86.45g

Therefore, the theoretical yield will be 86.45 grams.

Write the correct ionic formula when given two elements that bond ionically.
Tanzania [10]
Answer:
            Ionic bond is formed by the opposite ions attraction between the 2 atoms in an ionically bonded compound. The two ions i.e. Cation and Anions are formed by oxidation and reduction reactions respectively. General Ionic formula is as follow,

                                             Mⁿ⁺ + Nⁿ⁻   →  MN
where;
           Mⁿ⁺   =  Cation

           Nⁿ⁻   =  Anion

           MN  =  Salt

Explanation:
                   Ionic bond is the electrostatic forces of attraction between positively charged cations and negatively charged Anions. These forces are very stronger resulting in increasing several physical properties of Ionic compounds like melting point and boiling point e.t.c.

Example:

Sodium Chloride:
                           NaCl is formed by Na⁺ cation and Cl⁻ anion as follow,

Oxidation of Na;

                                      2 Na  →  2 Na⁺  +  2 e⁻
Reduction of Cl₂;

                                    Cl₂  +  2 e⁻  →  2 Cl⁻

Crystal Lattice formation is as follow,

                                  Na⁺  +  Cl⁻   →  NaCl

Se ha añadido un evaporador para una alimentación de 11500 kg/dia de zumo de pomelo de forma que evapore 3000 kg/dia de agua por
mamaluj [8]

Answer:

37 %.

Explanation:

¡Hola!

En este caso, para el problema descrito, conocemos la corriente de entrada y la de salida del agua, por lo que podemos obtener el flujo de la corriente que contiene el zumo a la salida una vez el agua fue evaporada:

F_{sol}=11500kg/dia-3000kg/dia=8500 kg/dia

Luego, por medio de un balance de zumo de limón en el evaporador en el cual la cantidad que entra es igual a la que sale con sus respectivas concentraciones:

x_z^{entra}*11500kg/dia=x_z^{sale}*8500kg/dia

Como la concentración del zumo a la salida es del 50 % (0.50), la de entrada es:

x_z^{entra}=\frac{x_z^{sale}*8500kg/dia}{11500kg/dia} =\frac{0.50*8500kg/dia}{11500 kg/dia}\\ \\x_z^{entra}=0.37

Que es igual al 37%.

¡Saludos!
