Answer : The correct option is, (C) 0.6 ml
Explanation : Given,
Initial volume of solution in the burette = 32.3 ml
Final volume of solution in the burette = 32.9 ml
As the liquid is colorless. So, we are taking the lower meniscus for the correct reading of the solution.
Now we have to calculate the total volume of solution that was dispensed from this burette.
Now put all the values in this formula, we get the total volume of solution that was dispensed from this burette.
Therefore, the the total volume of solution that dispensed from this burette was, 0.6 ml
(a) The molecular shapes of cis and Trans forms of N2F2 are-
b) There is EN difference between N atom and F atom. Hence the molecule will have a bond dipole.
In Cis form two fluorine atoms are on the same side of N N bond. Hence, bond moment in N2F2 cis form) do not cancel each other. Thus the cis form is polar.
In the trans form two fluorine atoms are on the opposite side of N-N bond. Bond moment of NF cancels each other.
Thus: trans N2F2 is non polar molecule.
Answer:
1.48 × 10²⁴ atoms
Explanation:
Step 1: Calculate the moles of argon
Argon is a noble gas, whose molar mass is 39.95 g/mol. We will use this data to find the moles corresponding to 98.1 grams of argon.
Step 2: Calculate the atoms of argon
In order to calculate the number of atoms of argon in 2.46 moles of argon, we have to consider the Avogadro's number: there are 6.02 × 10²³ atoms of Ar in 1 mole of Ar.
