how many moles of carbon monoxide can be produced from 8 moles of carbon if carbon is the limiting reagent?
Mademuasel [1]

Answer:

8 moles of CO

Explanation:

To produce carbon monoxide we begin from C and O₂ as this reaction shows:

2C + O₂ → 2CO

Therefore, 2 moles of C can produce 2 moles of CO

If I have 8 moles of C, I must produce 8 moles of CO

Ratio is 1:1

Which method is appropriate for separating a mixture of iron and aluminum?
zalisa [80]
The method which is appropriate for separating a mixture of iron and aluminum is A. using a magnet.
This is because aluminum does not have magnetic properties (thus it will be unaffected by the magnet), so it is easy to sort out all iron from the mixture using a magnet.

Two electrons are found in the same atom. One has the quantum number set (2, 1, -1, +½), and the other has the quantum number se
SCORPION-xisa [38]

Answer is: same orbital, but have different spin directions.

The principal quantum number (n) is one of four quantum numbers which are assigned to each electron in an atom to describe that electron's state.  

For principal quantum number n=2:  

1) azimuthal quantum number (l) can be l = 0...n-1:  

l = 0, 1.  

The azimuthal quantum number determines its orbital angular momentum and describes the shape of the orbital.  

2) magnetic quantum number (ml) can be ml = -l...+l.  

ml = -1, 0,+1.  

Magnetic quantum number specify orientation of electrons in magnetic field and number of electron states (orbitals) in subshells.  

3) the spin quantum number (ms), is the spin of the electron.  

ms = +1/2, -1/2.

Andrews [41]

Thrust acts on the spacecraft and propels in the space.

<h3>How space shuttles move?</h3>

1. The force created by the shuttle's engines in expelling the burning fuel produces an equal thrust in the opposite direction. This thrust acts on the spacecraft and propels in the space.

2. The thermosphere and the stratosphere are our hottest atmosphere layers because these two layers are present near the sun as compared to other layers of atmosphere.

3. When the meteors hit the atmosphere, meteors rub against air particles and create friction which is heating the meteors. The heat vaporizes most meteors, creating what we call shooting stars.
