What is the molarity of hcl found in a titration where 50 ml of hcl is titrated with 50 ml of .1 m naoh? needs to be answered asap rocky

0.1 mol/L . The concentration of the HCl is 0.1 mol/L

a)Write the balanced chemical equation

HCl + NaOH → NaCl + H2O

b)Calculate the moles of NaOH

Moles of NaOH = 0.050 L NaOH x (0.1 mol NaOH/1 L NaOH)

= 0.0050 mol NaOH

c)Calculate the moles of HCl

Moles of HCl = 0.0050 mol NaOH x (1 mol HCl/1 mol NaOH)

= 0.0050 mol HCl

d)Calculate the molar concentration of the HCl

c = moles/litres = 0.0050 mol/0.050 L = 0.1 mol/L

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.
