Look at the chemical equation.

Chemistry
1 answer:
dem82 [27]2 years ago
4 0

Answer:

See explanation

Explanation:

a) The total ionic equation shows all the ions involved in the equation as follows;

H^+(aq) + I^-(aq) + Li^+(aq) + OH^-(aq) ----> Li^+(aq) + I^-(aq) + H2O(l)

b) The net ionic equation only involves the ions that truly participated in the reaction.

H^+(aq) + OH^-(aq) ----> H2O(l)

c) The spectator ions appear on both sides of the reaction equation. They are; I^- and  Li^+.

d) The salt formed is LiI (lithium iodide)

Which answer is correct for the question below? Why would number <br> Two be incorrect?
Lapatulllka [165]
It would be 4 because the graph is showing the impact of heat on the enzyme not the pH. The pH in this instant is the constant and the graph does not indicate what a change in pH would do, only what a change in temperature would do.

If a hydrogen atom and a helium atom have the same kinetic energy:________
Nuetrik [128]

Answer: If a hydrogen atom and a helium atom have the same kinetic energy then the wavelength of the hydrogen atom will be roughly equal to the wavelength of the helium atom.

Explanation:

The relation between energy and wavelength is as follows.

E = \frac{hc}{\lambda}\\

This means that energy is inversely proportional to wavelength.

As it is given that energy of a hydrogen atom and a helium atom is same.

Let us assume that E_{hydrogen} = E_{helium} = E'. Hence, relation between their wavelengths will be calculated as follows.

E_{hydrogen} = \frac{hc}{\lambda_{hydrogen}}    ... (1)

E_{helium} = \frac{hc}{\lambda_{helium}}         ... (2)

Equating the equations (1) and (2) as follows.

E_{hydrogen} = E_{helium} = E'\\\frac{hc}{\lambda_{hydrogen}} = \frac{hc}{\lambda_{helium}} = E'\\\lambda_{helium} = \lambda_{hydrogen} = E'

Thus, we can conclude that if a hydrogen atom and a helium atom have the same kinetic energy then the wavelength of the hydrogen atom will be roughly equal to the wavelength of the helium atom.
