Alekssandra [29.7K]

Answer:

Explanation:

True or false 4 questions help please!

Most mixtures are not physical changes.

True

False   FALSE  when I add solid NaCl salt to water I no longer have a solid salt, I have a solution of sodium and chlorid ions in liquid water.  this is  physical change

Chemical Changes do not create a new substance.

True

False  FALSE 0ne of the proofs that you have a chemical change is the presence of a new substance

Fire is an example of a Chemical Change.

True  TRUE  fire is oxygen reacting wiIh mattter to form new compounds

False

Explosions are not chemical changes.

It depends on the explosion  if I blow up a balloon until it POPS!! that is physical chame.  If I light a firecracker and it explodes, that is a chemical change of oxygen reacting with hot gunpowder

A change in color and odor are both examples of chemical changi

I would rewrite the question as  

A change in color and odor  both INDICATE a chemical change

and that is

True  TRUE

False

F

True   Fire is an example of a Chemical Change.

Many classic experiments have given us indirect evidence of the nature of the atom. Which of the experiments below did not give
taurus [48]

The Rutherford experiment proved the Thomson “plum-pudding” model of the atom to be essentially correct did not give the results described and is denoted as option A.

<h3>What is Thomson “plum-pudding” model?</h3>

This model was proposed by J.J Thomson in which referred an atom as a sphere of positive charge, and negatively charged electrons are embedded in it to balance the total positive charge.

This model was incorrect and the Rutherford atomic model was adopted in which he described the electrons orbits about a tiny positive nucleus.

The nucleus contains protons and neutrons instead thereby making it the correct choice.

#SPJ1

The options include the following:

a.The Rutherford experiment proved the Thomson “plum-pudding” model of the atom to be essentially correct.

b.The Rutherford experiment was useful in determining the nuclear charge on the atom.

c.Milikan’s oil-drop experiment showed that the charge on any particle was a simple multiple of the charge on the electron.

d.The electric discharge tube proved that electrons have a negative charge
