Answer:
have stars that might appear to wobble
often have one star that is brighter than the other
Explanation:
A binary star system is a star system made up of mostly two stars that moves round their common fixed center.
The two orbiting stars are gravitationally bonded to one another and they move round each other.
Most binary stars might appear wobble. One of the stars often appears brighter than the other.
Its B cold air penetrating the hot water hope it helps
For the following alkyne structure, the hybridization of each carbon in the molecule is C1 = Sp3, C2=Sp3, C3=Sp, C4=Sp, C5= Sp3
Bond angle=
1)C1-C2-C3= 109 degree 28
2)C2-C3-C4=180 degree
3)C3-C4-C5= 180 degrees
Effective molecular charge order= S> Si> AI> Mg
What is hybridization?
In chemistry, orbital hybridization (or hybridization) is the concept of mixing atomic orbitals to form new hybrid orbitals (having different energies, shapes, etc. than the component atomic orbitals) suitable for electron pairing. Yes, they form chemical bonds through valence bond formation.
Hybridization is defined as the concept of mixing two atomic orbitals to create a new type of hybrid orbital. This mixing usually results in the formation of hybrid orbitals with very different energies, shapes, etc.

Answer:

Explanation:
Hello!
In this case, since the given reaction is:

Whereas the equilibrium constant is:
![K=\frac{[C][D]^{5/2}}{[A][B]^2} =4.0](https://tex.z-dn.net/?f=K%3D%5Cfrac%7B%5BC%5D%5BD%5D%5E%7B5%2F2%7D%7D%7B%5BA%5D%5BB%5D%5E2%7D%20%3D4.0)
However, the new target reaction reverses and doubles the initial reaction to obtain:

Whereas the equilibrium constant is:
![K'=\frac{[A]^2[B]^4}{[C]^2[D]^5}](https://tex.z-dn.net/?f=K%27%3D%5Cfrac%7B%5BA%5D%5E2%5BB%5D%5E4%7D%7B%5BC%5D%5E2%5BD%5D%5E5%7D)
Which suggest the following relationship between the equilibrium constants:

So we plug in to obtain:

Answer:
209.3 Joules require to raise the temperature from 10 °C to 15 °C.
Explanation:
Specific heat capacity:
It is the amount of heat required to raise the temperature of one gram of substance by one degree.
Formula:
Q = m × c × ΔT
Given data:
mass of water = 10 g
initial temperature T1= 10 °C
final temperature T2= 15 °C
temperature change =ΔT= T2-T1 = 15°C - 10°C = 5 °C
Energy or joules added to increase the temperature Q = ?
Solution:
We know that specific heat of water is 4.186 J/g .°C
Q = m × c × ΔT
Q = 10 g × 4.186 J/g .°C × 5 °C
Q = 209.3 J
