At liftoff, a space shuttle uses a solid mixture of ammonium  perchlorate and aluminum powder to obtain great thrust from the vo
klemol [59]

1 - A balanced equation for the reaction is 3NH4ClO4 + 3Al -------> Al2O3 + AlCl3 + 6H2O + 3NO

2 - Ammonium perchlorate is the oxidizing agent while aluminum powder is the reducing agent.

Molar mass of aluminum oxide = 102 g/mol;

The molar mass of ammonium perchlorate =117.5 g/mol.

From the equation of reaction 3 moles of ammonium perchlorate react with 3 moles of aluminum to produce 1 mole of aluminum oxide.

That is 3 x 7.5 g of ammonium perchlorate reacts with g of aluminum to produce 102 g/mol of aluminum oxide. Also 150g.

150 g of ammonium perchlorate produces (150 * 102)/(3*117.5) g of aluminum oxide = 43.4 g of aluminum oxide.

Can someone please help with chemistry? Lead has a density of 10.5 g/cm^3. What is the diameter of a lead ball that has a mass o
adelina 88 [10]
Density = Mass / Volume

10.5 = 500 / x

10.5x = 500

x = 50 cm^3 (1 sig fig) volume of the sphere

Volume of a sphere = 4/3 pi r^2

pi = 3.14 r = radius

50 = 4/3 pi r^3

50•3/4 = pi r^3

37.5 = pi r^3

37.5/pi = r^3

11.9 = r^3

cube root(11.9) = r

2.3 = r

Diameter = 2•radius

Diameter = 2 • 2.3

Diameter = 5 cm (1 sig fig) diameter

How many carbon dioxide (CO2) molecules are produced during the decomposition of 1.25 moles of Carbonic acid (H2CO3)? ****Rememb
Andreas93 [3]

Answer:

7.53×10²³ molecules

Explanation:

Given data:

Number of moles of carbonic acid =  1.25 mol

Number of molecules of CO₂ produced = ?

Solution:

Chemical equation:

H₂CO₃   →     CO₂ + H₂O

Now we will compare the number of moles of carbonic acid with CO₂ from balanced chemical equation.

                                 H₂CO₃      :        CO₂

                                    1             :           1

                                   1.25         :       1.25

Number of molecules can be determine by using Avogadro number.

It is the number of atoms , ions and molecules in one gram atom of element, one gram molecules of compound and one gram ions of a substance.

The number 6.022 × 10²³ is called Avogadro number.

Number of molecules:

1 mole = 6.022 × 10²³ molecules

1.25 mol ×  6.022 × 10²³ molecules  / 1 mol

7.53×10²³ molecules
