The fastest animal in the world is the peregrine falcon. It is capable of diving after its prey at an amazing 83.00 meters per second. How fast this is the penguin going in miles per hour? Speed conversion tiles
A. 128.0 miles/hour
B. 185.7 miles/hour
C. 298.8 miles/hour
D. 371.1 miles/hour

185 mph

Explanation:

Use an extended equation to convert all the units of measure to the units you need in your answer.  Units of measure on the top will cancel the same units of measure on the bottom.  You'll be left with Miles on the top and Hours on the bottom.

83 m        1 km         0.62 mi     60 sec       60 min          185 miles

B. 185.7 miles/hour

Explanation:

1 meter per second = 2.237 miles per hour.

Multiply 83*2.237, which then equals 185.671.

c is having 4 valence electrons and is bonded to three hydrogens and one sulphur atom, therefore, the number of bond pair is equal to four. as all the valence electrons are used in forming the bonds so, there is no lone pair left on carbon.

s is having 6 valence electrons and is bonded to one other sulfur atom and one carbon atom, therefore, the number of bond pair is equal to 2. as only two valence electrons are used in forming the bonds so, four electrons are left. therefore, two lone pairs are present on s.
