What is an atom? how can we predict it?

1 answer:

5 0

An atom is the what makes up elements. It is made up of positive particles (protons), negative particles (electrons), and neutrons (no charged particles).

Protons and neutrons are in the center of the atom while electrons hover around.

You cannot predict an atom. This is because it is not anything to guess about -if you know what I mean.

Happy to help!

Can you please help solve and explain the steps for the calculation?

Nimfa-mama [501]

Answer:

The hydrogen ion concentration in a solution, [H+], in mol L-1, can be calculated if the pH of the solution is known.

pH is defined as the negative logarithm (to base 10) of the hydrogen ion concentration in mol L-1 pH = -log10[H+] ...

[H+] in mol L-1 can be calculated using the equation (formula): [H+] = 10-pH

serg [7]

<u>Answer :</u>

Part 13:

The balanced chemical reaction will be:

$Cu(NO_3)_2+Na_2SO_4\rightarrow CuSO_4+2NaNO_3$

Part 14:

The balanced chemical reaction will be:

$Cu(NO_3)_2+Na_2C_2O_4\rightarrow CuC_2O_4+2NaNO_3$

Part 15:

The balanced chemical reaction will be:

$Cu(NO_3)_2+2KOH\rightarrow Cu(OH)_2+2KNO_3$

<u>Explanation :</u>

Balanced chemical reaction : It is defined as the reaction in which an individual element of an atom present on reactant side must be equal to product side.

Part 13:

The balanced chemical reaction will be:

$Cu(NO_3)_2+Na_2SO_4\rightarrow CuSO_4+2NaNO_3$

Part 14:

The balanced chemical reaction will be:

$Cu(NO_3)_2+Na_2C_2O_4\rightarrow CuC_2O_4+2NaNO_3$

Part 15:

The balanced chemical reaction will be:

Why is an electron ejected when green light hits the metal?

Roman55 [17]

Explanation:

If a large photon strikes the surface, that has enough strength to take out an electrode, which will then travel to the positive side since it is negative. Current is flowing at this stage. Since the reduced photons will be unable to distinguish between atoms, no power can pass.
