Answer: Copper is being reduced
Explanation:
F = 13 N
<h3>Further explanation</h3>
Given
Acceleration= a = 2.6 m/s²
Required
Force
Solution
Newton's second law :
ΣF = m x a
The wheeled cart used in the experiment is the same, so the mass used is the same
We use one of the data for example data 1 to find mass :
F = 1 N, a = 0.2 m/s²
m = F/a
m = 1/0.2
m = 5 kg
so for acceleration= a = 2.6 m/s² :
F = 5 kg x 2.6 m/s²
F = 13 N
Answer:
Oxidation states are used in chemistry solutions. It is a bond in which electron transfers easily from one nucleus to another nucleus.
Explanation:
- Oxidation-reduction reactions have some rules.
- The oxidation state is 0 at an uncombined bond.
- The bond of oxidation reduction is +1 in alkeli metal.
- The bond in two metal is +2
- The oxidation reduction state at helogens is -1. It does not happened always.
- The oxygen bond in oxidation and reduction is -2.
- The sum of the oxidation state is equal to the compound charges.
- In this process the changes occur for any elements. Redox could be occur. Its oxidized and reduction reaction can be seen in this process.
Explanation:
If the number of atoms of each element in reactants is not equal to the number of atoms of each element present in product, then the chemical equation is called unbalanced chemical equation
Yes, i expect to find an atom with 26 protons and mass number of 52, because if it has different number of neutrons it could be a type of isotope. As if there is different number of neutrons in an atom, they make an isotopes of that atom and if we add the number of neutrons and number of protons we will find the mass number of that atom.
