What is the representative particle for barium chloride?

2 answers:

8 0

Barium chloride is salt with ionic bonds. Barium chloride contains one barium cations (charge of ion is 2+) and two chlorine anions (charge for ion is 1-).
The representative particle of an ionic compound is its formula unit (lowest whole number ratio of ions in an ionic compound), for barium chloride that is BaCl₂.

Answer: The chemical formula for the given compound is $BaCl_2$

Explanation:

Barium chloride is formed by the combination of barium and chlorine atoms. This compound is ionic compound because electrons get transferred from one atom to another atom.

Barium is the 56th element of the periodic table. It is a metal and it looses its electrons. The electronic configuration for this element is $[Xe]6s^2$

This element will loose 2 electrons and forms $Ba^{2+}$ ion.

Chlorine is the 17th element of the periodic table. It is a non-metal and it gains electrons. The electronic configuration for this element is $[Ne]3s^23p^5$

This element will gain 1 electron and forms $Cl^-$ ion.

Hence, the chemical formula for the given compound is $BaCl_2$

Given the following data, determine the order of reaction with respect to H2.

alex41 [277]

Answer:

First-order with respect to hydrogen.

Explanation:

Hello!

In this case, considering that the rate law of this reaction can be expressed via:

$r=k*p_{H_2}^m*p_{ICl}^n$

If we want to know m, the order of reaction with respect to hydrogen, we need to relate the experiments 1 and 3 in order to get rid of the pressure of ICl:

$\frac{r_1}{r_3} =\frac{k*p_{H_2,1}^m*p_{ICl,1}^n}{k*p_{H_2,3}^m*p_{ICl,3}^n}$

Thus, we plug in the given rates, and pressures to get:

$\frac{1.34}{0.266} =\frac{k*250^m*325^n}{k*50^m*325^n}$

So we can cancel wout k and 325^n:

$\frac{1.34}{0.266} =\frac{250^m}{50^m}$

Next we solve for m, the order of reaction with respect to hydrogen:

$5.04 =5^m\\\\log(5.04)=m*log(5)\\\\m=\frac{log(5.04)}{log(5)} \\\\m=1.0$

It means it is first-order with respect to hydrogen.

Regards!

Does the boiling point of a liquid depend of the amount of liquid

nignag [31]

A liquid boils at a temperature at which its vapor pressure is equal to the pressure of the gas above it. The lower the pressure of a gas above a liquid, the lower the temperature at which the liquid will boil. Boiling point represents a phase change of matter. So no, the boiling poibt of a liquid does not depend on the amount of liquid

if the mass of a material is 46 grams and the volume of the material is 5 cm^3 what would the density of the material be?

Firlakuza [10]

We use the following formula for calculating the density:

p = m/v

Where:
m = mass
v = volume

So, we have:

p = 46 /5
p = 9,2 g/cm³
