Answer:
Wavelenght is 7,79x10⁻⁵ m
Explanation:
The equation that connects wavelentgh (λ) and frequency (ν) is:
λ=c/ν
Where c is speed of light (3x10⁸ m/sec) and λ is expressed in lenght´s units and ν is expressed in "time⁻¹ " units (for example, sec⁻¹)
According to the details, if we just replace the given value of frequency, we just obtaing wavelenght data:
λ= (3x10⁸ m/sec)/(3,85x10¹² sec⁻¹) = 7,79x10⁻⁵ m
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:
B
Explanation:
Iodine has a negative charge, so it will gain electrons.
Answer:
Intensive
Explanation:
Intensive because it only depends on the type of matter and not the amount. Overall, I say intensive because it will not change when you change the amount of matter.
Answer:
provide steels-specific bins to families and provide people to collect the cans
Explanation:
The recycling process plays an important role in the saving of the environment. Recyling of steel cans uses less energy than manufacturing something from the scratch. In addition, the process creates jobs for the people. There are number of recycling usints that are making a living. In order to make the process faster and easier, the coucile can encourage each househild to have a can bin. This will be dedicated to the alumininium cans. This makes iyt easuetr to dispose the bins abs tha vcans. In addition, the council can employ more people who move from house to house collecting the cans.
