Answer:
1. chloroplast
2. they prevent some proteins to function how they normally function
Explanation:
Answer:
neutron
Explanation:
protons plus neutrons equal the mass of the atom
The correct answer is:
a positron is emitted when proton converts to a neutron.
The reaction can be described as following:
₁¹p (proton) → ₀¹n (neutron) + ₁°e (positron or ₁⁰β)
Positron is an antiparticle of a β particle (₋₁°β), which means it has an oposite charge to it, but same mass.
<u>Answer:</u> The molar solubility of MX is 
<u>Explanation:</u>
We are given:
The chemical equation for the ionization of MX follows:
S S
The expression of 
for above equation is:
......(1)
The chemical equation for the ionization of 
follows:
0.25M 0.5M 0.25M
Total concentration of cation from both the equation is:
![[M^+]=0.5+S](https://tex.z-dn.net/?f=%5BM%5E%2B%5D%3D0.5%2BS)
As, 
, so S is also very very less than 1 and can be easily neglected.
So, ![[M^+]=0.5M](https://tex.z-dn.net/?f=%5BM%5E%2B%5D%3D0.5M)
Putting values in equation 1, we get:
Hence, the molar solubility of MX is
Solution:
By the following ways the polar molecule doesn’t mix with non-polar molecule
Polar molecules have a portion of their molecule which, relative to the rest of the molecule, is more negative.
Water, for example, has a bent, or V-shape, due to the 2 lone electron pairs on oxygen. This makes the oxygen end more negative than the hydrogen end. This negative area allows for hydrogen bonding between that molecule and other molecules which are also polar.
Non-polar molecules don't have a portion of the molecule which is more negative than the rest. An example of this is a hydrocarbon, like butane. Because there is no relatively negative region to the molecule, it cannot partake in hydrogen bonding and therefore does not mix with polar molecules.
Thus we can conclude that Polar mixes with polar; non-polar mixes with non-polar.
