Answer: The reaction mixture contains large amounts of reactants
Explanation:
The equilibrium constant (K) tells the degree to which a chemical reaction will progress.
So, a very small equilibrium constant (K≪ 1) tells of a reaction that has the concentration of the products as small, while the concentration of the reactants is large.
MgS2o3 weights (24.305) + 3(16) grams pre mole so if you divide 181 g by that number you will have the number of moles. Grams*(moles/grams)=moles
Answer:
D. Radar uses radio, and the siren uses sound waves.
Explanation:
The main difference between the siren passing by and the radar is that radar uses radio waves and siren uses sound waves.
- Sound waves are mechanical waves which requires a material medium for their propagation.
- In a vacuum, the sound waves cannot pass through freely.
- Radar is an electromagnetic wave.
- It is particular of radio waves origin.
- Such waves do not require a material medium for their propagation and hence can be transmitted through a vacuum.
Bohr's model explained the position of the electron, proton, and neutron in the atom of the element. The energy at the n = 2 level of the atom will be - 3.40 eV.
<h3>What is the principal quantum number (n)?</h3>
The principal quantum number (n) has been the distance of the electron of that atom in the nucleus and its energy in the structure. It can also be said to define the size of the atomic orbit.
n = 2 is the first excited state whose energy is calculated as:
Eₙ = − 13.6 ÷ n² eV
E₂ = - 13.6 eV ÷ 2²
= -3.40 eV
Therefore, -3.40 eV is the energy of electron at n = 2.

Answer:
(CH2)3CH3 > CH2CH2CH3 > CH2CH3 > CH3
Explanation:
Giving the following ; CH3, CH2CH3, CH2CH2CH3, (CH2)3CH3
Priority increases as the number of CH2 group increases and vice versa, as such the one with more CH2 group will be the highest priority and the least compound with the small CH2 group attached, will have the smallest priority.
The arrangement is as follows ; (CH2)3CH3 > CH2CH2CH3 > CH2CH3 > CH3
