A group of scientists affiliated with the International Geosphere-Biosphere Programme (IGBP) have proposed a new framework to account more accurately for the effects of aerosols on precipitation in climate models.The increase in atmospheric concentrations of man-made aerosols-tiny particles suspended in the air-from such sources as transportation, industry, agriculture, and urban land use not only poses […]
The five-satellite RapidEye commercial Earth observation constellation launched successfully on Friday aboard a silo-based Dnepr rocket from Russia’s Baikonur Cosmodrome in Kazakhstan. All five satellites have sent signals and are healthy in low Earth orbit, the satellite’s owners and the prime contractor said.
Brandenburg, Germany-based RapidEye AG, formed 10 years ago to build what was to […]
Ocean warming is spurring the incidence of virulent coral diseases, already wreaking havoc on reefs worldwide.
David Bourne and colleagues at the Australian Institute of Marine Science (AIMS) said global warming and increased sea surface temperatures presented a major challenge to the health of the world’s coral reefs.
Warming has caused significant damage to reefs in recent […]
Monkeys can experience the joy of giving in much the same way as humans do, U.S. researchers reported on Monday.Tests in capuchin monkeys showed the animals consistently chose to share food with another monkey if given the option, suggesting they are capable of empathy, the team at the Yerkes Research Center at Emory University in […]
In another frustrating foul-up on the path towards converting Soviet-era military missiles into cash-paying satellite launchers, a military-industrial team in Moscow has announced the ‘indefinite suspension’ of plans to launch an earth resources survey satellite for Thailand.
The reasons: at the last moment, for the second time, overflight permission has been revoked by a country downrange […]
Rainbows have colors because of refraction. The different colors of the visible portion of the electromagnetic spectrum are separated based on their wavelength and frequency. The color with the lowest frequency and longest wavelength, which is red, is placed at the top. The color with the highest frequency and shortest wavelength, which is […]
Where is anesthesia injected in your body and does it matter where the anesthesia injected according the the surgery that is going to be taken on you?
It depends what part of the body needs to be put to sleep.
Usually arms, belly, & major arteries. Or sometimes they use pills, or they actually use […]
Calculate pH:
25mL of .2 M CH3OOH + 10 mL of .2 M NaOH? Ka= 1.8E-5
Step-by-step procedure please! I have to do 20 of these!
Moles of acid:
0.025L * 0.2mole/L = 0.005 moles
Moles of NaOH:
0.01L * 0.2mole/L = 0.002moles
Concentration of acid:
0.005mol/0.030L = 0.17M
Concentration of NaOH:
0.002mol/0.030L = 0.07
Ka= [CH3COO-][H+]/ [CH3OOH]
1.8E-5 = X^2/0.17
X= 0.00175M = [H+]
*NaOH dissociates […]
Depends on how you define hot. Most of the carnivorous plants, like the venus flytrap, enjoy hot tropical whether but not desert like conditions.
