Since the action and reaction are exactly equal and oppositely directed , how can there be a net force on an object ?
erma4kov [3.2K]

Answer: Net force is the summation of all the forces involved or acting on an object.

Explanation: For action and reaction situation it states that the Fa = -Fb. Both forces with equal magnitudes but opposite direction will cancel out each other having a zero net force.

Answer:

\boxed{\text{40 mol Al}}

Explanation:

            Al₂O₃ ⟶ 2Al + 3O₂

n/mol:     20

\text{Moles of Al} = \text{20 mol Al$_{2}$O$_{3}$}\times \dfrac{\text{2 mol Al}}{\text{1 mol Al$_{2}$O$_{3}$}}= \textbf{40 mol Al}\\\text{You can produce }\boxed{\textbf{40 mol Al}}

1. Find the number of protons, neutrons, electrons and electronic structure of flourine 919F.
77julia77 [94]

1. ₉¹⁹F

2. Mg(OH)₂

3. 2H₂ + O₂ ⇒ 2H₂O

<h3>Further explanation</h3>

1. Fluorine, atomic number : 9 , mass number = 19

Symbol : ₉¹⁹F

protons=electrons=atomic number = 9

neutrons = mass number - atomic mass

\tt n=19-9=10

Configuration : [He] 2s² 2p⁵

2. Magnesium hydroxide is an ionic compound and is a strong base consisting of 2 ions:

Positive ion: Magnesium: Mg²⁺

negative ion: Hydroxide: OH⁻

The charges of the two are crossed, so that the compound becomes:

Mg(OH)₂

3. Reaction :

H₂ + O₂ --------> H₂O

give coefficient :

aH₂ + bO₂ --------> H₂O

H, left = 2a, right 2⇒2a=2⇒a=1

O, left = 2b, right 1⇒2b=1⇒b=0.5

Reaction becomes :

H₂ + 0.5O₂ --------> H₂O x 2

2H₂ + O₂ --------> 2H₂O

Which statement best describes a property of a compound? A compound is made up of a single atom. B. A compound is made up of man
Pavlova-9 [17]

Answer:

D. A compound can be separated into two or more elements through a chemical reaction.

Explanation:

By method of elimination, we are going t obtain the correct  option.

A. A compound is made up of a single atom.

This is wrong because, a compound can contain more than one atom.  An example is H2O

B. A compound is made up of many atoms that are all the same type.

This is wrong because a compound can contain atoms of different elements. An example is H2O. It contains atoms of hydrogen and oxygen.

C. A compound can be separated into two or more elements through physical processes.

This is wrong. H2O being a compound cannot be separated by ordinary physical means.

D. A compound can be separated into two or more elements through a chemical reaction.

This is the correct option.
