How many grams of AlCl3 can be prepared from 3.5 moles of HCl gas?

Chemistry
1 answer:
poizon [28]3 years ago
4 0

Answer:

156 g of AlCl₃ will be produced from 3.5 moles of HCl.

Explanation:

Given data:

Number of moles of HCl = 3.5 mol

Grams of AlCl₃ produced = ?

Solution:

Balanced Chemical equation:

3HCl + Al(OH)₃   →  AlCl₃ + 3H₂O

Now we will compare the moles of AlCl₃  with HCl from balanced chemical equation.

                   HCl          :           AlCl₃

                     3            :              1

                   3.5           :           1/3×3.5 = 1.17 mol

Mass of  AlCl₃ produced:

Mass = number of moles ×molar mass

Mass = 1.17 mol ×   133.341 g/mol

Mass =  156 g

Thus 156 g of AlCl₃ will be produced from 3.5 moles of HCl.

jarptica [38.1K]
The soda can from the car will lose CO2 more quickly. This is because of the kinetic energy and behavior of gas molecules under different temperatures. CO2 is more soluble in cold temperatures than hot. Cold temperatures minimize the kinetic energy of gas molecules; thus, preventing the gas from escaping the soda. This is why soda that comes from the refrigerator has more fizz or spirit than soda at room temperature.

The density of lava is 3.1 g/cm². It has a volume of 2700 cm3. How much does this block of lava weigh?
konstantin123 [22]

Answer:

Mass of lava is 8370 g.

Explanation:

Density:

Density is equal to the mass of substance divided by its volume.

Units:

SI unit of density is Kg/m3.

Other units are given below,

g/cm3, g/mL , kg/L

Formula:

D=m/v

D= density

m=mass

V=volume

Symbol:

The symbol used for density is called rho. It is represented by ρ. However letter D can also be used to represent the density.

Given data:

density of lava = 3.1 g/cm³

volume= 2700 cm³

mass= ?

Solution:

d = m/v

m = d×v

m = 3.1 g/cm³×2700 cm³

m = 8370 g

Information about how a chemical reacts under high pressure can be found in the ""reactivity"" section of a msds. True or false?
dezoksy [38]

Information about how a chemical reacts under high pressure can be found in the "reactivity" section of a MSDS: True.

<h3>What is MSDS?</h3>

MSDS is an abbreviation for Material Safety Data Sheet and it can be defined as a text-based document which is designed and developed to provide more information with respect to the chemical and physical properties of an equipment, chemical compound, or substance, based on the following:

  • Reactivity
  • Flammability
  • Temperature
  • Radioactivity

In this context, we can infer and logically deduce that it is true that the information about how a chemical react would under high pressure can be found in the "reactivity" section of a Material Safety Data Sheet (MSDS).
