In earths surface or the bottom of the Ocean
Answer:
Option D - It tells which compounds will dissolve in water.
Explanation:
It is used to predict whether or not a given ionic compound is soluble.
Answer:
Irrigation is the artificial process of applying controlled amounts of water to land to assist in production of crops. Irrigation helps to grow agricultural crops, maintain landscapes, and revegetate disturbed soils in dry areas and during periods of less than average rainfall.
The correct options are as follows:
1. In the chemical equation given above, Fe3+ IS REDUCED.
A reduction is a process in which an atom of an element gains an electron and therefore become reduced. In this type of reaction, the positive character of the atom is reduced. Looking at the equation given above, you will notice that, the positive character of Iron is reduced form +3 to +2.
2. In the reaction given above, the chlorine atom is OXIDIZED.
An oxidation is a process in which an atom loses an electron, thereby increasing its oxidation number. In this case, the positive character of the atom is increased. Looking at the chlorine atom given above, you will notice that it has a charge of -1 before and now it has change to neutral, which means that, it has given out the electron it gains earlier.
3. This type of redox reaction can not take place. This is because, in chemical reaction, the chlorine atom is always looking for another element that will donate an electron to it in order to become stable. Thus, chlorine atom easily gain electrons but it can not donate an electron to another element.<span />
Answer:
Nitrogen monoxide and oxygen are called the reactants
Explanation:
Step 1: Given data
Nitrogen monoxide = NO
Oxygen = O2
Step 2: Balanced equation
2NO + O2 → 2NO2
This means that 2 moles of NO will be consumed and and 1 mole of O2 to produce 2 moles of NO2
This means NO2 is the prodcut that is produced.
NO +O2 react with eachother, to form NO2
This means nitrogen monoxide (NO) and Oxygen (O2) are called the reactants.
