July 11, 201412 yr The question about a chemical reaction. I know a nail rusting is a chemical reaction. What type of reaction is sugar dissolving in warm water? I don't remember 7th Grade. Water boiling is a heat related reaction, cannot think of the term for that. Change in form, not chemical makeup. Or change of state - solid-liquid-gas. I believe the correct answer to this is dissolution.
July 11, 201412 yr Those were really easy. 13/13 I'm sure nitrogen through a lot of people. Got that one right. Part of the 5th grade curriculum that I recently spent much time reviewing.
July 11, 201412 yr Science and Technology Knowledge Quiz Results You answered 13 of 13 questions correctly. I was surprised that the atmosphere gas question was missed by so many. Only 31% of college grads got it right and the best score in all the other demographic groups was 25% answering correctly. The toughest question for me that I had to really think about was the chemical reaction.
July 11, 201412 yr I believe the correct answer to this is dissolution. Correct. When sugar dissolves, it doesn't become liquid sugar, so it isn't a change of state. Dissolution is the best answer. 13/13 for me.
July 11, 201412 yr 13 for 13. And for those of you that missed the atmosphere question...please get a full face piece supplied air respirator on quick...that 78% carbon monoxide air your breathing isn't good for you.:lol:
July 11, 201412 yr Kinda like saying you have the best naval fleet in Nebraska. We use only top of the line screen doors on our nuclear subs!
July 11, 201412 yr Word home skillet 13/13 Just reverse the polarity of the neutron flow... solves any science problem you might have. Easy peasy.
July 11, 201412 yr 13. Nailed it. *drops mic* This, but I was wearing a clip-on mic, so I just fell over.
July 11, 201412 yr 12 out of 13. Missed the laser question. It says I didn't answer the easy one about the continents moving, but I know I did.
