By referring to particles, explain why the white ring formed in the glass tube

Answers

Answer 1

Answer:

Ammonia and Hydrogen Chloride.

Explanation:

Assuming this is what you're referring to, Ammonia (NH3) and Hydrogen Chloride(NCI3). The concentrated ammonia (NH3) is placed on a pad in one end of a tube and hydrochloric acid (NCI3) on a pad at the other. Shortly after the gases will begin diffusing far enough to meet, a ring of solid ammonium chloride (NH4Cl) will be formed.

If you have 4.01 g of H2, how many grams of NH3 can be produced?

Answers

Answer:

136.5886g of NH3

Explanation:

N2 + 3H2 = 2NH3

The mass of the N2 = 4.01

3H2 has a 2/1 ratio

This means the mass of 3H2 is twice as much as N2.

NH3= 2*N2 = 2*4.01 = 8.02 of NH3

Then, by multiplying the mass by MX (17.031)

8.02*17.031=136.5886g can be produced. Round it if needed.

physics

BY The Editors of Encyclopaedia Britannica | View Edit History

ion, any atom or group of atoms that bears one or more positive or negative electrical charges. Positively charged ions are called cations; negatively charged ions, anions. Ions are formed by the addition of electrons to, or the removal of electrons from, neutral atoms or molecules or other ions; by combination of ions with other particles; or by rupture of a covalent bond between two atoms in such a way that both of the electrons of the bond are left in association with one of the formerly bonded atoms. Examples of these processes include the reaction of a sodium atom with a chlorine atom to form a sodium cation and a chloride anion; the addition of a hydrogen cation to an ammonia molecule to form an ammonium cation; and the dissociation of a water molecule to form a hydrogen cation and a hydroxide anion.

Describe how you could show by adding aqueous sodium hydroxide and aqueous ammonia that a solution contained zinc ions.

Ionic compounds are compounds that contain an ion pair. Typically, ionic compounds are formed between metals and nonmetals.

The degree of ionic character depends on the type of metal involved and the magnitude of charge it carries.

Typically, first row transition metals form ionic compounds. The degree of ionic character depends on the row in which the metal is found and the magnitude of charge it carries.

What determines an object’s ability to float?

Answers

Simply put, density is how tightly “stuff” is packed into a defined space.

For example, a suitcase jam-packed with clothes and souvenirs has a high density, while the same suitcase containing two pairs of underwear has low density. Size-wise, both suitcases look the same, but their density depends on the relationship between their mass and volume.
Mass is the amount of matter in an object.
Volume is the amount of space that an object takes up in three dimensions.

Density is calculated using the following equation: Density = mass/volume or D = m/v.

If something is heavy for its size, it has a high density. If an object is light for its size it has a low density.

The relative densities of an object and the liquid it is placed in determine whether that object will sink or float.

If the concentrations of both and were increased 10 times, what would happen to the rate of the reaction? Classify the conversion of acetyl chloride to methyl acetate as an addition, elimination, or substitution.

Answers

If the concentration of acetyl chloride  is increased ten times the rate of reaction is increased ten times.

The conversion of acetyl chloride to methyl acetate is a substitution reaction. Recall that a substitution reaction is one in which a moiety in a molecule is replaced by another.

In this reaction, the CH3O- ion replaces the chloride ion. In the first step, the CH3O- ion attacks the substrate in a slow step. This creates a tetrahedral intermediate. Loss of the chloride ion yields the  methyl acetate product.

The rate determining step is the formation of the tetrahedral intermediate. Since the reaction is first order in the acetyl chloride, if its concentration is increased ten times the rate of reaction is increased ten times.

Determine the amount of grams present in
3.25x1024 atoms of Lithium.

Answers

Answer:

Explanation:

Molar mass of Lithium is 6.9410 g/mol.

This means 1 mol of Li atoms weigh 6.9410 g

In 1 mol 6.022 x 10 ^ 23 atoms should be present

So, in 6.9410g , there should be 6.022 x 10 ^ 23 atoms.

So weight of 1 atom = a =  6.9410  g / (6.022 x 10^ 23)

To find weight of 3.25 x 10 ^ 24 atoms we have to multiply a by 3.25 x 10^ 24

So you will get the answer as

[6.9410  g / (6.022 x 10^ 23)]   x 3.25 x 10^ 24

= 37.46 g

The number of moles present in 29.5 grams of argon is 0.74 mole.

The atomic mass of argon is given as;

Ar = 39.95 g/mole

The number of moles present in 29.5 grams of argon is calculated as follows;

39.95 g ------------------------------- 1 mole

29.5 g ------------------------------ ?

A volume of 10.0 mL of 25 mg/L Mn2+ solution was diluted to make a solution with the final volume of 50.0 mL. Calculate the concentration (in mg/L) of the final solution

Answers

Taking into account the definition of dilution, the concentration of the final solution is 5 mg/L.

First of all, you have to know that dilution is the reduction in concentration of a chemical in a solution.  The process consists of adding more solvent to the same amount of solute.

In a dilution the amount of solute does not change, but as more solvent is added, the concentration of the solute decreases.

A dilution is mathematically expressed as:

Ci×Vi = Cf×Vf

where

Ci: initial concentration Vi: initial volume Cf: final concentration Vf: final volume

In this case, you know:

Ci= 25 mg/L  Vi= 10 mL Cf= ? Vf= 50 mL  

Replacing in the definition of dilution:

25 mg/L × 10 mL= Cf × 50 mL

Solving:

Cf= (25 mg/L × 10 mL)÷ 50 mL

Cf=  5 mg/L

In summary, the concentration of the final solution is 5 mg/L.
