What is the limiting react any when 5.6 moles of aluminum react with 6.2 moles of water

You first need to show the amount of aluminum you have and how much water you need to make a mole ratio. The one that isn't in excess is the limiting reactant

5.6 mol of Al*2/1=11.2 mol Al

6.2 mol of H2O*3/1=18.6 mol H2O

11.2<18.6

Al<H2O

This could be that aluminum is the limiting reactant

:)

i think its 5049.

i hope this !

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.
