Explanation:
Since the state of matter is going from a gas to a solid, it would be going from a state of high entropy (greater disorder) to a state of lower entropy (less disorder).
Answer:
what language is this in? Do you want it translated?
Explanation:
The appropriate answer is c. Scientists get the information from past climates by melting ice cores retrieved from boring the ice and retrieving cores. The air is trapped in the ice as little bubbles and as the ice melts the gases are retrieved. Ice cores are taken from regions such as the Greenland ice sheets. Scientists have tested air samples thousands of years old.
Answer:
Methane + Bromine = (CH4+Br2)
Explanation:
When a mixture of methane and bromine is exposed to ultraviolet light - typically sunlight - a substitution reaction occurs and the organic product is bromomethane. However, the reaction doesn't stop there, and all the hydrogens in the methane can in turn be replaced by bromine atoms. The reaction is a single-step reaction.
