Chemistry question?
I am not asking for a short and sweet answer to the question below, I have an exam tomorrow and this question is from the study guide my professor handed out to us. I really do not get thermochemistry so someone please help me.
2.50g Au(s) at 1063 degrees Celsius is cooled to 150 degrees Celsius. Calculate the energy transferred in kJ. You may need this information for gold:
Cs(l)= 0.148 J/g C
Cs(s)=0.13 J/g C
Gold DeltaH fusion= 64 J/g
Melting point of Au= 1063 degrees celsius
boiling point of Au= 2807 degrees celsius
I'm guessing you have to add q of Gold and delta H fusion and set it to equal to zero, but again, I am so confused and stressed out
1 AnswerChemistry4 years agoHow much can I get from my car accident?
Last November, my boyfriend and I were involved in an accident. A man was trying to turn left from a street perpendicular to ours, and saw our car approaching at 40 miles per hour (within speed limit) and stopped in the middle of the road in panic. My boyfriend could not swerve in time, so we collided into the man's car. I was in the passenger's seat, which took the most damage, and the adjuster concluded that the car was totaled (all airbags deployed, front completely wrecked). Both my boyfriend and I had to miss school and work because of the accident. My neck was swollen and very tender because of the seatbelt, and my thigh had a huge purple and yellow bruise on it. I also could not turn my head in a specific direction, otherwise a very sharp pain would occur, and my boyfriend got a first degree burn on his hands from the airbag. I am super grateful that we both got out of the accident alive and all body parts intact, but I was wondering if we'd get anything from the pain we had to go through? We also had to attend chiropractor appointments for three months, three times each week, which was a biiiiiigggg pain in the butt (working around a schedule like that was baloney!!) I know it all depends on several factors, but I was wondering if anyone went through a similar experience and may know of an estimated amount?
Thank you for those who read this!!! I am not hungry for money, I am just a curious george! :)

Could be for commercial, recreational, or military drone use. Do you think that we need to add more regulations to the use of drones?

6 AnswersFashion & Accessories9 years agoBest swimsuit for me?
okay, so summers already here, and my friends and I are planning to go to the beach, but Im in need of a new swimsuit!
I have a very short torso, no curves- just straight, no hipbones, and stomach fat. But almost everyone says I'm super skinny, so imagine skinny legs and arms but with stomach fat.
anyways, which swimsuit best fits my body type?? I really like the retro, vintagey stuff like this http://www.hm.com/us/product/01705?article=01705-A but I'm afraid it wont suit me.

2 AnswersRoyalty9 years agoSomeone please heeelppppppp ..?
Someone please put this paragraph into words I can understand ?? I'm so freaking stressed out right now because my group isn't doing crap and I'm the only freaking one doing all the work please heeelppp mee or I'll shoot myself.
July Revolution, revolt in France in July, 1830, against the government of King Charles X. The attempt of the ultraroyalists under Charles to return to the ancien régime provoked the opposition of the middle classes, who wanted more voice in the government. The banker Jacques Laffitte was typical of the bourgeois who supported liberal journalists, such as Adolphe Thiers, in opposing the government. Liberal opposition reached its peak when Charles called on the reactionary and unpopular Jules Armand de Polignac to form a new ministry (Aug., 1829). When the chamber of deputies registered its disapproval, Charles dissolved the chamber. New elections (July, 1830) returned an even stronger opposition majority. Charles and Polignac responded with the July Ordinances, which established rigid press control, dissolved the new chamber, and reduced the electorate. Insurrection developed, and street barricades and fighting cleared Paris of royal troops. Charles X was forced to flee and abdicated in favor of his grandson, Henri, conte de Chambord. Henri was set aside, and, although there was a movement for a republic, the duc d'Orléans was proclaimed (July 31) king of the French as Louis Philippe. His reign was known as the July Monarchy.
1 AnswerWords & Wordplay9 years ago1830 French Revolution?..?
Can someone give me KEY FACTS about the 1830 French Revolution? (like when it started, why it started, who was involved, etc..... Like causes and effects and other information that will help me understand) Please don't give me a huge paragraph with a bunch of big words, because that's what wikipedia is like (or other websites), and it's so hard to even understand the first sentence.
It would help if you put the information in bullet points so it's easier to understand, and this is not for my homework, it's to help me understand what the heck the 1830 French Revolution is lol.
THANKSSSS (:(:(:(:(:(:(:
