<u>Answer:</u> The molarity of saline solution is 0.909 M
<u>Explanation:</u>
We are given:
5.21 w/w % NaCl
This means that 5.21 grams of NaCl is present in 100 grams of solution
To calculate mass of a substance, we use the equation:
Density of solution = 1.02 g/mL
Mass of solution = 100 g
Putting values in above equation, we get:
To calculate the moalrity of solution, we use the equation:
Given mass of NaCl = 5.21 g
Molar mass of NaCl = 58.44 g/mol
Volume of solution = 98.04 mL
Putting values in above equation, we get:
Hence, the molarity of saline solution is 0.909 M
V= d/t
v=speed
d=distance
t=time
So v= 422/3
v =140.667m/s
The MC1R gene provides instructions for making a protein called the melanocortin 1 receptor. This receptor plays an important role in normal pigmentation. The receptor is primarily located on the surface of melanocytes, which are specialized cells that produce a pigment called melanin.
Answer:
D
Explanation:
From my experience this is what happens when I put sugar in warm water glass
The statement which is not true is as follows:
- The repulsive force between electrons on different atoms does not matter at all.
Thus, the correct option is C.
<h3>What is Equilibrium?</h3>
An equilibrium may be defined as the condition in which both the reactants and products are present in concentrations that have no additional propensity to alter with time so that there is no noticeable transformation in the possessions of the system.
The causation of repulsive force was thought to be made by the overlap of atomic orbitals and in between the electrons of diverse atoms, it matters a lot.
The equilibrium distance between nuclei of two covalently bonded atoms is called the bond length of that atom. It is the atomic separation at equilibrium.
Equilibrium occurs when the attractive and repulsive forces neglected the effect of each other in a specific state.
Therefore, it is well described above.
