What is the ratio between the coefficients of any two substances in a balanced equation?

In a balanced chemical equation, we have two numbers that indicate two different factors. The definitions of these numbers are as follows:

1- Molar ratio: This ratio represents the ratio between the number of moles of any two substances in the balanced equation

2- The coefficients in the balanced chemical equation: These numbers represent the numbers of particles of each of the substances taking place in this chemical equation.

A hydrogen-like ion is an ion containing only one electron. The energy of the electron in a hydrogen-like ion is given by:

kupik [55]

hydrogen-like ion is an ion containing only one electron. The energy of the electron in a hydrogen-like ion is given by:

En = −(2.18 × 10^−18J) Z^2 ( 1/n^2 )

where n is the principal quantum number and Z is the atomic number of the element. Plasma is a state of matter consisting of positive gaseous ions and electrons. In the plasma state, a mercury atom could be stripped of its 80 electrons and therefore could exist as Hg80+. Use the equation above to calculate the energy required for the last ionization step.hydrogen-like ion is an ion containing only one electron.

Under what circumstances will a scientific theory be changed or discarded

VMariaS [17]

If new evidence or observations falsify a scientific theory, the theory will have to be changed to adapt to the new data or just discarded altogether.

Explain some of the benefits and problem associated with the pesticide DDT.

Dafna1 [17]

Some benefits are that DDT helps us grow crops and keeps pests off our crops.

But DDT is harmful to the environment. If it gets into the water ways then if can harm fish and animals that eat the fish such as birds.
