There is 1 OH- in 1 molecule of NaOH.
Also, there is 1 H+ in 1 molecule of lactic acid.
So the reaction is simple.
so just equate the moles
moles of OH- in NaOH = moles of H+ in lactic acid
26.8 x 0.07 = 250 x Mole of lactic
Moles of lactic = 0.0075
so mass = 0.0075 x 90.8 = 0.681 g
Answer:
The answer is: Applied Chemistry
Explanation:
Apllied Chemistry is a branch of Chemistry that deals with the application and use of Chemistry principles and theories to answer a specific question or solve real world problems. It is aimed at taking Chemistry knowlege from the classroom to the real world. In this example, Marie noticed that a problem had arisen, and that is corrosion of metals, and she set out to apply the principles of Chemistry to make a paint formulation that prevvents corrosion, not just on paper with a bunch of formulas and calculations, but translated into a real life substance. On the other hand, pure Chemistry is the theoretical aspect of Chemistry, where the result of the researches are purely for knowlege and not for real world application.
I believe the most appropriate answer would be to change the core from wood to iron. This is because iron is a magnetic material while wood is not magnetic hence cant acquire magnetism. Other factors that would increase the strength of electromagnet would be; increasing the amount of electric current, and increasing the number of windings.
Answer:
Decrease
Explanation:
Since the speed in which the gas molecules are faster as they are heated, they fly around in the container and logically, it is harder to insert a moving object into water than something more stationary or slower.
