Q. How many molecules of H2O can be produced from reactants in container below?
A. 3 molecule of molecules H2O will be produced from reactants in container.
<em><u>Explanation</u><u>:</u></em>
There are seven molecules of H2 and three molecule of O2 are there in the container Q, 6 molecules of H2 will react with 3 molecules of O2 to produce 3 molecules of H2O. One molecule of Hydrogen will not take part in reaction and will be present in container Q after then reaction, and the mass in overall reaction is conserved!

<u>Answer:</u> The correct answer is 0.745 km
<u>Explanation:</u>
We are given:
A numerical value of 815 yards
To convert this into kilometers, we use the conversion factor:
1 km = 1093.6 yards
Converting the given value into kilometers, we get:
![\Rightarrow 815yd\times \frac{1km}{1093.6yd}=0.745km](https://tex.z-dn.net/?f=%5CRightarrow%20815yd%5Ctimes%20%5Cfrac%7B1km%7D%7B1093.6yd%7D%3D0.745km)
Hence, the correct answer is 0.745 km
