Determine the correct name for the compound, c3h8. in organic chemistry, this is referred to as propane. a) tricarbon hexahydride b) tricarbon octahydride c) tetracarbon octahydride d) tetracarbon hexahydride

The correct name for the compound is tricarbon octahydride.

(C) is correct option.

Explanation:

The given compound   is a covalent compound. the compounds in which there is a sharing of electrons between  two elements is called covalent compound. here, there is sharing of electrons between hydrogen and carbon.

Hydrogen and carbon are non metal and hence will form covalent bond.

Property of the name of covalent bond is given by,

(I). First we have to write the name more electronegative element and then less electronegative element.

(II). The atoms of an element is greater than 1, then we add to prefixes which are  as follows,

For 1 atom = mono

For 2 atom = di

For 3 atom = tri

For 4 atom = tatra

For 5 atom = penta

For 6 atom = hexa

For 7 atom = septa

For 8 atom = octa and so on.

So, The name of the compound will be tricarbon octahydride

Hence, The correct name for the compound is tricarbon octahydride.  

the minimum constant speed at which she can catch the train is 2.7 m/s

given:

acceleration = 0.6

time = 4.5 s

to find:

velocity = ?

formula used:

from 1st kinematic equation we get,

v = u + at

u = initial speed of train = 0 m/s

v = final speed of the train

a = acceleration of the train

t = time

solution:

from 1st kinematic equation we get,

v = u + at

u = initial speed of train = 0 m/s

v = final speed of the train

a = acceleration of the train

t = time

v = 0 + (0.6 × 4.5)

v = 2.7 m/s

the minimum constant speed at which she can catch the train is 2.7 m/s

note: the given question is incomplete.

complete question is given below.

which is an example of kinetic energy?

a. the energy stored in ethanol  

b. a hockey puck sliding across the ice  

c. a compressed spring  

d. a ball sitting at the top of a ramp

solution: the kinetic energy is the energy posses by the virtue of the motion of the object.

in the given options, a, c and d are the example of potential energy because it is the energy posses by the virtue of the rest of the object. but option b has the kinetic energy as the object is in motion.

hence, a hockey puck sliding across the ice   is the apex example of kinetic energy.

so, the option (b) a hockey puck sliding across the ice   is the correct option.
