Rainbow [258]

Answer:

5 hours

Explanation:

Given:

Distance = 275 km

Speed = 55 km/h

speed =  \frac{distance}{time}

time =  \frac{distance}{speed}

time = \frac{275}{55}

time = 5

How many moles of H2 would be required to produce 37.0 moles of water?
svp [43]

Hii there !

The reaction accompanying production of water in this case would be -

\green{ \underline { \boxed{ \sf{H_2+ \frac{1}{2}O_2\longrightarrow H_2O}}}}

Thus ,by observing the reaction, we can conclude that 1 mole of Hydrogen (H_2)react with 1/2 mole of oxygen(O_2)to produce 1 mole of water (H_2O)

\impliesTherefore, 37.0 moles of hydrogen(H_2) will be required to produce 37.0 moles of water.

Hope it helps.

Georgia [21]

<u>Answer</u>:

According to Bohr's theory, an electron's path around the nucleus defines its

energy level.

<u>Explanation</u>:

It the certain energy by which the electrons have occupied there place in the orbitals. They can also be moved to the higher energy level by taking the energy from the surrounding. The emission of light can be seen when the electron falls from the higher energy state to the lower state. The orbital that is close to the atomic centre having the lowest energy level and the one that is found to be far away from the atomic centre has the highest energy level.
