How would you obtain a pure sample of hydrogen in a lab?
I don't think you can really. The most common way of separating hydrogen is electrolysis of water, but this requires huge amounts of electricity, and is therefore inefficient.
Which type of reaction requires more activation energy?
endothermic reaction
What is a reaction that requires energy?
endothermic
During the course of which type of reaction is energy consumed?
Any reaction that consumes energy, or has a positive delta(H), is called an endothermic reaction.
What metabolic reaction requires oxygen and glucose?
respiration

Is the splitting of water into hydrogen and oxygen a exothermic reaction?
No. It is endothermic as it requires energy.
What evidence of chemical change is visible when electricity is run through water?
Water can be chemically changed, for instance, when an electric current is run through a sample, separating it into oxygen and hydrogen gas. Chemical change requires a chemical reaction, a process whereby the chemical properties of a substance are altered by a rearrangement of the atoms in the substance.Added:What is visible: it is gas bubles of hydrogen and oxygen coming out from the electrodes: O2 at the positive anode, H2 at the negative cathode.
Why do plasma TVs throw off so much heat?
The electronic reaction to provide light requires a large amount of electricity, which causes heat.
Desalination is expensive because it requires what?
Desalination requires a lot of of energy or electricity, which makes it expensive.
What is a reaction that requires heat?
Endothermic reaction
Is it possible for fusion reaction to be happening at a planets core?
No. Fusion requires high concentrations of Hydrogen. Planets are made from substantially heavier elements. Additionally, a planet massive enough to begin a fusion reaction literally becomes a star.
Is it possible for fusion reaction to be happening at planet's core?
No. Fusion requires high concentrations of Hydrogen. Planets are made from substantially heavier elements. Additionally, a planet massive enough to begin a fusion reaction literally becomes a star.
What are the limitations of information technology?
limitations are IT requires electricity, old and young people may have trouble using it, and IT requires maintenance limitations are IT requires electricity, old and young people may have trouble using it, and IT requires maintenance
Which type of reaction requires more activation energy?
endothermic reaction

endothermic
Why does the three gorges dam need electricity?
The three gorges dam requires electricity because of its size, it also requires electricity because the electricity that it recieves from the water isnt enough to power it, so they decided to power the dam separately and send the electricity gained to the power stations.
