A voltaic cell is based on the reduction of ag (aq) to ag(s) and the oxidation of sn(s) to sn2 (aq).

Annette [7]

Half-reaction for the cell's anode is given below:

Anode : $\\Sn(s) \rightarrow Sn^{2+} (aq) +2e^{-}$

The anode is defined as the electrode at which electrons leave the cell and oxidation occurs, and the cathode as the electrode at which electrons enter the cell and reduction occurs. The anode is usually the positive side.

If a hydrogen atom has its electron in the n = 3 state, how much energy in ev is needed to ionize it?

tensa zangetsu [6.8K]

The energy of the hydrogen atom will be -0.85 ev.

Ionization, also known as ionization, would be the phenomenon by which an atom or molecule gains or loses electrons to acquire a negative and positive charge, frequently in conjunction with those other chemical changes. Ions are the name for the electrically charged molecular or atom that results.

These chemicals are known as ionic compounds, with table salt serving as an example. Ionization would be the process of removing electrons from such an element as well as a molecule as well as the dissociation of an ionic material, such as salt, itself into the individual ions in a solution like water.

The energy of hydrogen atom will be calculated by using the formula:

$E_{n} = -13.6 ev / n^{2}$

where, $E_{n}$ = energy of nth level, n is the state.

It is given that, n = 3 .

Now put the value of n in above equation.

$E_{4} = -13.6 ev / 4^{2}\\E_{4} = -13.6 ev / 16\\E_{4} = -0.85 ev$

Therefore, the energy of the hydrogen atom will be -0.85 ev.

If a gas in a closed container is pressurized from 15.0 atmospheres to 16.0

Yuki888 [10]

Answer:

T₂ = 317.87 K

Explanation:

Given data:

Initial pressure = 15 atm

Final pressure = 16 atm

Initial temperature = 298 K

Final temperature = ?

Solution:

According to Gay-Lussac Law,

The pressure of given amount of a gas is directly proportional to its temperature at constant volume and number of moles.

Mathematical relationship:

P₁/T₁ = P₂/T₂

Now we will put the values in formula:

15 atm / 298K = 16 atm/T₂

T₂ = 16atm × 298 K / 15 atm

T₂ = 4768 atm. K / 15 atm

T₂ = 317.87 K

Forming a hypothesis is accomplished through _______ reasoning.

vfiekz [6]

Deductive reasoning involves making broad observations and examining possibilities to reach a specific, logical conclusion, which is required in the formation of a hypothesis. Conversely, inductive reasoning involves taking specific observations and making broad generalisations from these. Therefore the answer is A.

Hope this helps!
