Which volume of ethane gas, in cm3 , will produce 40cm3 of carbon dioxide gas when mixed with 140cm3 of oxygen gas, assuming the

Gemiola [76]

The volume of ethane gas, C₂H₆ in cm³ that will react to produce 40 cm³ of CO₂ is 20 cm³

<h3>Balanced equation </h3>

2C₂H₆ + 7O₂ —> 4CO₂ + 6H₂O

From the balanced equation above,

4 cm³ of CO₂ were obtained from 2 cm³ of C₂H₆

<h3>How to determine the volume of C₂H₆ needed </h3>

From the balanced equation above,

4 cm³ of CO₂ were obtained from 2 cm³ of C₂H₆

Therefore,

40 cm³ of CO₂ will be obtain from = (40 × 2) / 4 = 20 cm³ of C₂H₆

Thus, 20 cm³ of C₂H₆ are required for the reaction.

Could Rutherford make any conclusions about electrons based on the result of experiment?

MatroZZZ [7]

Answer:

They are so small that they barely make up any of the mass of the atom, and they are so miniscule that during Rutherford 's Gold foil experiment ,they didn't even react with the alpha particles. They circle the nucleus on a ring. shown through Rutherford Atomic Model

Write the balanced molecular and net ionic equations for the reaction between aluminum metal and silver nitrate. identify the ox

asambeis [7]

Well in this case, silver nitrate is reduced:

Ag+ + e− → Ag(s) ↓

Meanwhile, the aluminum is oxidized forming a positive ion:

Al(s) → Al3+ + 3e−

To get the overall reaction, we add the half equations so that the electrons are eliminated:

Al(s) + 3Ag+ → Al3+ + 3Ag(s)

And similarly:

Al(s) + 3AgNO3(aq) → Al(NO3)3(aq) + 3Ag(s)

Electrons are found in energy levels around the nucleus of an atom. Energy levels can also be called ""shells."" The energy leve

melamori03 [73]

Answer:

The first electronic shell or energy level, having n= 1, called the K shell, is the closest to the nucleus.

Explanation:

In an atom, the sub atomic particles called electrons, revolve around the nucleus of the given atom at different energy levels, called shells.

The energy levels or the electronic shells are denoted by the principal quantum number (n) and has the following values n = 1, 2, 3, 4, 5, 6, 7; from the innermost shell to the outermost.

The electron shells are also labelled by the alphabets, K, L, M, N, O, P, and Q, from the innermost shell to the outermost.

Thus the first electronic shell having n= 1, called K shell, is the lowest energy level and is present closest to the nucleus.

Whereas, the last electronic shell having n =7, called Q shell, is the highest energy level and is farthest from the nucleus.
