Explanation:
The given precipitation reaction will be as follows.
Here, AgCl is the precipitate which is formed.
It is known that molarity is the number of moles present in a liter of solution.
Mathematically, Molarity = 
It is given that volume is 1.14 L and molarity is 0.269 M. Therefore, calculate number of moles as follows.
Molarity =
0.269 M = 
no. of moles = 0.306 mol
As molar mass of AgCl is 143.32 g/mol. Also, relation between number of moles and mass is as follows.
No. of moles = 
0.307 mol = 
mass = 43.99 g
Thus, we can conclude that mass of precipitate produced is 43.99 g.
Answer:
- <u><em>Option A.) 2 ppm</em></u>
Explanation:
<u><em>60 particles in 30 million</em></u> can be expressed as a fraction:
And, dividing both numerator and denominator by 30, that can be simplified as:
That means 2 particles of sulfur dioxide in 1 million particles of sample, which is 2 parts per million or<u> 2 ppm</u>, which is the option A.
Atomic radius is the distance from the nucleus to the last valance electron up to which the effect nucleus can be felt. The size of the atom depends on the Electrostatic interaction between nucleus and electron. Number of atomic orbitals present. With the increase in numbers of orbitals down the group the size of the atom increases. Again, as the numbers of electrons increases in the period ,the electrostatic interaction between nucleus and electron increases along the period. Therefore, size of atoms decreases along the period.
As expected the element with highest atomic radius is the last element of group 1 , Which is FRANCIUM ( Fr)
Answer:
Heat is transferred from the warmer block to the cooler block
Explanation:
Heat transfer by conduction involves two or more solids. The heat generally moves from a part at higher temperature to one with a lower temperature.
- Heat transfer is based on the differences in temperature profile on a body.
- When the temperature of the body is the same, heat is not transferred.
- The molecules that makes up the hotter body collides with static molecules of the cold one.
- Through this, heat is transferred.
Answer:
c. 3.
Explanation:
pOH = -log(1x10^-11)
14-11 = 3 (pOH + pH = 14)
