Answer:

Explanation:

The early ideas of the atom states that the indivisible object is hollow or is a solid object with nothing inside. The later discoveries or works of the scientists states that inside the atoms are the subatomic particles which are the electrons, protons, and neutrons.

Write the balanced electrochemical reaction for when zinc reacts with a copper solution. Label what is being oxidized and what i

Fed [463]

The balanced equation would be $Zn + Cu^{2+} ---- > Cu + Zn^{2+}$

<h3>Electrochemical equations</h3>

Zn reacts with Cu solution according to the following equation:

$Zn + Cu^{2+} ---- > Cu + Zn^{2+}$

In the reaction, $Cu^{2+}$ is reduced according to the following: $Cu^{2+} + 2 e^- -- > Cu$

While Zn is oxidized according to the following: $Zn - 2e^- --- > Zn^{2+}$

Thus, giving the overall equation of; $Zn + Cu^{2+} ---- > Cu + Zn^{2+}$

Pls help ASAP........ A student was roasting marshmallows over a fire. The student

Phantasy [73]

Answer:

A chemical change

Explanation:

The marshmallow turning brown and bubbling implies that a chemical change has taken place.

For chemical changes to occur, we observe any of the following:

a new kind of matter is formed.
it is always accompanied by energy changes
the process is not easily reversible
it involves a change in mass
requires considerable amount of energy.

ii. Two signs that shows a chemical change has taken place is that:

bubbles are being formed as it is roasted and it implies that new substances have been formed.
also, significant amount of heat energy is supplied for the roasting.

What is the<br> total charge of 1 proton, 1 electron, and 1 neutron?

iragen [17]

Given parameters:

Number of protons = 1

Number of electrons = 1

Number of neutrons = 1

unknown:

Total charge = ?

Atoms are made up of elementary particles of protons neutrons and electrons.

Protons are the positively charged particles in an atom

Electrons are the negatively charged particles

Neutrons do not carry any charges

To find the total charge on an atom; simply find the difference between the number of protons and electrons.

Total charge = Number of protons - number of electrons

= 1 - 1

Total charge is 0

Therefore, the total charge is zero, 0
