The complex ion [cobr6]3− is a high-spin complex and absorbs light at a wavelength greater than 7.70×102 nm . how many unpaired electrons will be present in the complex?

Where are the following questions

The answer is falsegravitational force is independent of medium and depends only on the masses of the two objects and the distance between them.

In reversible reaction chemistry equilibrium is attained when the forward and reverse reactions are taking place at the same rate, thus, the concentrations of reactants and products remain the same. a reversible reaction is a chemical reaction where the reactants form products that, in turn, react together to give the reactants back. in irreversible reactions on the other hand, the reactants react to form the products, which cannot revert back into reactants.

Because calorimetry is used to measure the heat of a reaction, it is a crucial part of thermodynamics. in order to measure the heat of a reaction, the reaction must be isolated so that no heat is lost to the environment. this is achieved by use of a calorimeter, which insulates the reaction to better contain heat.
