copy word for word though Explanation:

Simulation of a reaction is a chemical reaction modeling or demonstration tool, using various software to better understand the molecular structure and the physical and chemical properties of the molecule. Here the actual reaction is N2 + 3H2 -----> 2NH3. In the simulation reactions, the nitrogen and hydrogen molecules in the actual reaction are described by different colored circles or dots and the bonds are produced using a single, double or triple line that touches each molecule and gives an appearance like the reactants and the products' ball and stick model. Example: Molecule of nitrogen as o---triple line---o. A molecule of hydrogen as O———O. Chemical symbols such as N and H are expressed in Actual Chemical Reaction, N2 and H2 and the bonds are represented by single, double or triple lines that do not impact the atoms in the molecule as follows: Nitrogen Molecule: N -triple Bond- N. Hydrogen Molecule: H - H.

Answer:

Explanation:

Moles of N2 = 35.0g / (28g/mol) = 1.25mol

Moles of H2 = 60.0g / (2g/mol) = 30.0mol

Since 1.25mol * 3 < 30.0mol, nitrogen is limiting.

Moles of NH3 = 1.25mol * 2 = 2.50mol.

Mass of NH3 = 2.50mol * (17g/mol) = 42.5g.

30.0mol - 1.25mol * 3 = 26.25mol.

Excess mass of H2

= 26.25mol * (2g/mol) = 52.5g.

The empirical formula of the compound is called the formula unit in chemistry. In 1.5 moles of magnesium bromide, [tex]9.03\times 10^{23}[/tex] formula units are present.

Moles are the measuring units of the molecules, atoms, and other particles of the chemistry. Formula units of any substance can be estimated as the product of the moles and the Avogadros number.

The number of the moles present of the magnesium bromide is 1.5 mol and the value Avogadro number is [tex]6.02 \times 10^{23}.[/tex]

If 1 mole of the substance contains [tex]6.02 \times 10^{23}[/tex] formula units, then, formula units in 1.5 moles are:

[tex]\begin{aligned} & = 1.5 \times 6.02 \times 10 ^{23}\\\\& = 9.03 \times 10^{23} \end{aligned}[/tex]

Therefore, [tex]9.03 \times 10^{23}[/tex] formula units are present in 1.5 moles of magnesium bromide.

Explanation:

you make use of the formulas

amount(mol) = number of particles ÷ 6.02 × 10^23

and

mass(g) = amount(mol) × molar mass

Answer:

C) ionic compounds

Explanation:

Only ionic compounds takes place in a chemical double displacement reaction.

The reaction involves an actual exchange of partners to form a new compounds.

These compounds involved are ionic compounds.

The atomic mass of the metal.(M) = 51 g/mol

Given

32% of oxygen

Required

the atomic mass of the metal.​

Solution

An oxide of trivalent metal : M₂O₃(Ar O = 16 g/mol)

The molar mass of metal oxide = 2M+16.3=2M+48

32% of oxygen, then :

32% x 2M+48 = 48

0.32(2M+48)=48

0.64M+15.36=48

0.64M=32.64

M=51

Answer:

375.8 × 10²³ molecules

Explanation:

Given data:

Number of molecules of acetylene = ?

Volume of cylinder = 1400 L

Temperature = standard = 273.15 K

Pressure = standard = 1 atm

Solution:

The given problem will be solve by using general gas equation,

PV = nRT

P= Pressure

V = volume

n = number of moles

R = general gas constant = 0.0821 atm.L/ mol.K  

T = temperature in kelvin

PV = nRT

1 atm × 1400 L = n ×  0.0821 atm.L/ mol.K    × 273.15 K

1400 L.atm = n × 22.43  atm.L/ mol

n = 1400 L.atm / 22.43  atm.L/ mol

n = 62.4 mol

1 mole contain 6.022 × 10²³ molecules

62.4 mol × 6.022 × 10²³ molecules / 1 mol

375.8 × 10²³ molecules

Explanation:

Answer: The density of chloroform is 1.47 g/mL

Explanation : Given,

Volume = 40.5 mL

Mass of cylinder = 85.16 g

Mass of cylinder and liquid = 145.10 g

First we have to calculate the mass of liquid (chloroform).

Mass of liquid = Mass of cylinder and liquid - Mass of cylinder

Mass of liquid = 145.10 g - 85.6 g

Mass of liquid = 59.5 g

Now we have to calculate the density of liquid (chloroform).

Formula used:

[tex]Density=\frac{Mass}{Volume}[/tex]

Now putting g all the given values in this formula, we get:

[tex]Density=\frac{59.5g}{40.5mL}[/tex]

[tex]Density=1.47g/mL[/tex]

Therefore, the density of chloroform is 1.47 g/mL

Answer:

427.5g

Explanation:

Given parameters:

Number of moles  = 4.5moles

Unknown:

Mass of MgCl₂  = ?

Solution:

To solve this problem;

     Mass  = number of moles x molar mass

Molar mass of MgCl₂  = 24 + 2(35.5) = 95g/mol

  Mass  = 4.5 x 95  = 427.5g

Answer:

V = 12.5 L

Explanation:

Given data:

Volume of NO = 15.0 L

Temperature and pressure = standard

Volume of nitrogen gas produced = ?

Solution:

Chemical equation:

6NO + 4NH₃    →     5N₂ + 6 H₂O

Number of moles of NO:

PV = nRT

n = PV/RT

n = 1 atm × 15.0 L / 0.0821 atm.L /mol.K × 273.15 K

n = 15.0 atm.L / 22.43 atm.L /mol

n = 0.67 mol

now we will compare the moles of No and nitrogen gas.

              NO           :         N₂

               6             :          5

              0.67         :         5/6×0.67 = 0.56

Volume of nitrogen gas:

 PV = nRT

1 atm × V = 0.56 mol ×  0.0821 atm.L /mol.K × 273.15 K

V = 12.5 atm.L / 1 atm

V = 12.5 L
