9.) 4NH +50 ->4NO + 6H0
If 4.8 L of O, are used how many liters of NO and water are formed?

A. 3.2L of NO

B. 4.8L of H2O

Explanation:

We'll begin by writing the balanced equation for the reaction. This is given below:

4NH3 + 5O2 —> 4NO + 6H2O

A. Determination of the litres of NO produced from the reaction. This is illustrated below:

From the balanced equation above,

5L of O2 produced 4L of NO.

Therefore, 4L of O2 will produce = (4x4)/5 = 3.2L of NO.

B. Determination of the litres of H2O produced from the reaction. This is illustrated below:

From the balanced equation above,

5L of O2 produced 6L of H2O.

Therefore, 4L of O2 will produce = (4x6)/5 = 4.8L of H2O

it can be observed without changing the identity of the object.

it depends on what substance you're talking about as well as many other factors. in quantum mechanics, the observation of particles affects the observers ability to measure certain properties. for example: you can know the velocity of a particle, but you can't know it's position; or you can know it's position, but not it's velocity. it's like trying to find out where a grain of sand is by throwing other grains of sand at it. once you find out where it is, it's been moved. it's also like trying to find an answer to the question of whether or not a tree falling in a forest makes a sound if nobody is there to hear it. paradoxically, the only way to find out is to be there and hear it.
