Answer:
See explanation and image attached
Explanation:
The compound SF4 is sulphur tetraflouride. It has a zero formal charge and has a total of 34 valence electrons.
The central atom in the molecule is sulphur in an sp3d hybridization state hence the molecule has a trigonal bipyramidal electron geometry. Since it is a molecule of the sort AX4E; it gives a see-saw molecular shape.
The structure of the molecule is shown in the image attached to this answer.
Molality= moles/ Kg of solvent
You need to change the grams to moles. Since you did not say what the solute is, I can't change the grams to moles.
This is given by Avogagro number: 1 mol = 6.02*10^23 particles
Then you can do whichever to these two relations, because they are equivalent:
- 1mol / 6.02*10^23 representative particles, and
- 6.02*10^23 representative particle /1 mol
Only the second option of the question includes one of the valid conversion factors. Then, the conversion factor of the second option is the right answer
During exercise , his body responds by an increase in the heart rate and his
respiratory rate.
<h3>What is Exercise?</h3>
Exercise refers to the activities which are done to improve the physical
fitness of an individual. Examples include:
The heart and respiratory rate are increased to ensure enough oxygen is
available to the cells of the body. This helps to ensure carbohydrate is
broken down to energy which is used by the body cells during the exercise
being performed.
