What is the name of the compound BaCl2?

Nitric oxide (NO) reacts readily with chlorine gas as follows.2 NO(g) + Cl2(g) equilibrium reaction arrow 2 NOCl(g)At 700. K the

Yanka [14]

Answer:

For a: The mixture will need to produce more reactants to reach equilibrium.

For b: The mixture will need to produce more reactants to reach equilibrium.

For c: The mixture will need to produce more products to reach equilibrium.

Explanation:

For the given chemical equation:

$2NO(g)+Cl_2(g)\rightleftharpoons 2NOCl(g)$

The expression of $K_{p}$ for above equation follows:

$K_{p}=\frac{(p_{NOCl})^2}{(p_{NO})^2\times p_{Cl_2}}$ .....(1)

We are given:

Value of $K_p$ = 0.26

There are 3 conditions:

When $K_{p}>Q_p$ ; the reaction is product favored.
When $K_{p}$ ; the reaction is reactant favored.
When $K_{p}=Q_p$ ; the reaction is in equilibrium.

For the given options:

For a:

We are given:

$p_{NOCl}=0.11atm\\p_{NO}=0.16atm\\p_{Cl_2}=0.30atm$

Putting values in expression 1, we get:

$Q_p=\frac{(0.11)^2}{(0.16)^2\times 0.30}=1.57$

As, $K_{p}$ ; the reaction is reactant favored

Hence, the mixture will need to produce more reactants to reach equilibrium.

For b:

We are given:

$p_{NOCl}=0.048atm\\p_{NO}=0.12atm\\p_{Cl_2}=0.10atm$

Putting values in expression 1, we get:

$Q_p=\frac{(0.048)^2}{(0.12)^2\times 0.10}=1.6$

As, $K_{p}$ ; the reaction is reactant favored

Hence, the mixture will need to produce more reactants to reach equilibrium.

For c:

We are given:

$p_{NOCl}=5.20\times 10^{-3}atm\\p_{NO}=0.15atm\\p_{Cl_2}=0.15atm$

Putting values in expression 1, we get:

$Q_p=\frac{(5.20\times 10^{-3})^2}{(0.15)^2\times 0.15}=0.008$

As, $K_{p}>Q_p$ ; the reaction is product favored.

Hence, the mixture will need to produce more products to reach equilibrium.

Which property do metalloids share with nonmetals

Vesnalui [34]

Answer:

Explained below

Explanation:

Metalloids are elements that possess properties between that of metals and non - metals or that have properties that a re a combination of those of metals and non - metals. Whereas a metal is one that conducts electricity and heat very well.

Now, the property they both share is that they both possess valence orbitals which are highly de-localized over macroscopic volumes, thereby allowing both of them to be conductors of electricity although it has to be said that Metalloids don't conduct electricity as much as metals.

How does the atomic arrangement of atoms lead to its crystal structure like was seen in the sample of bronze and gold and Timber

Margaret [11]

In mineralogy and crystallography, a crystal structure is a unique arrangement of atoms in a crystal. Atomic arrangement of atoms in this kind of structure usually very symmetrical and highly ordered. Causing the component within the structure is so strong and hard to break. A crystal structure is composed of a unit cell, a set of atoms arranged in a particular way; which is periodically repeated in three dimensions on a lattice. Crystal structure would be commonly found in solid compounds.

DIMENSIONAL ANALYSIS PLSSSS convert 19 inches to feet(show work)

Anna [14]

19 in = 1.6 ft

You know that

12 in = 1 ft

If you divide both sides by 12 in, you get the conversion factor: 1 = 1 ft/12 in.

If you divide both sides by 1 ft, you get the conversion factor: 12 in/1 ft = 1.

Both are conversion factors because they both equal one and multiplying a measurement by one does not change its value.

You choose the conversion that gives you the correct dimensions for your answer. It must have the correct dimensions on top (in the numerator),

Thus, to convert 19 in to ft, you use the conversion factor with “ft” on the top.

∴ Length = 19 in × (1 ft/12 in) = 1.6 ft

In the step gradient separation, four separate fractions were collected. How were these related to the polarities of the column

max2010maxim [7]

These related to the polarities of the column and of the eluting solvent When you run a column are
1) always start with a more non-polar solvent ratio and SLOWLY increase the polarity of the solvent.
1) Columns are generally made with silica which is highly polar, so compounds that are more polar in nature will interact with the silica more than those that are non-polar.
3) The first fractions to come out should be most non-polar, with each fraction collected after that being more and more polar.
hope this helps
