Answer:
total disance covered by car=2858.11 meters
Explanation:
First calculate the time for which the given energy can be used
total energy=52700 joules;
756 joules used in every second;
total time=69.71 sec;
speed of car=41 m/s;
Number of meters the car travels=
number of meters the car travels=
number of meers the car travel=2858.11 meters

The hybrid orbital of this molecule is . Hence, option C is correct.
Hybridization is defined as the concept of mixing two atomic orbitals to give rise to a new type of hybridized orbitals.
In this compound, a hybrid orbital makes I-O bonds. Due to
hybridization iodate should have tetrahedral geometry but because of the presence of lone pair of electrons the shape of
the ion is pyramidal.
The hybrid orbital of this molecule is . Hence, option C is correct.

Answer: 3.306 mmol
Explanation:
Molarity of a solution is defined as the number of moles of solute dissolved per Liter of the solution.
where,
Molarity
n= moles of solute
= volume of solution in ml
According to stoichiometry:
1 mole of gives 2 moles of
1.653 mmol of gives =
of
Thus number of millimoles of are 3.306
