Proprietățile fizice ale mineralelor depind in cea mai mare măsură de compozitie chimică si structura reticulara reprezintă importanta deosebită în recunoașterea mineralelor
<span> a scientist would do after forming a testable question is </span>test the question.
Photosynthesis takes place in all ecosystems. Without it we would not be able to survive. Photosynthesis starts with plants. Plants are autotrophs which means they make their own food. During photosynthesis, plants take in sunlight, carbon dioxide (CO^2), and water during photosynthesis. They give off glucose and oxygen. Plants have chlorophyll in them which gives them their green color. Heterotrophs eat other living things to get energy. (If you want to go more into depth you can say this: Heterotrophs take in the glucose and oxygen. This is called cellular respiration. The products of cellular respiration are water, ATP (energy), and CO^2 which than leads you back to photosynthesis) Hope this helped! :)
Answer:
1 and 2
Explanation:
When Concentrated H2SO4 reacted with the alcohols, they produce cycloalkenes. This is a mechanism known as dehydration of alcohols with an acid catalyst. This is because concentrated H2SO4 acts as a great oxidizing agent. In the process, the alcohols are heated to a high temperature with an excess of pure sulfuric acid. By passing the gases through a sodium hydroxide solution, the carbon dioxide and sulfur dioxide produced by reactive species are eliminated. The reaction mechanism shown in the image below indicates that only compounds 1 and 2 produce only one product.
Answer:
1,372,800,000 Feet
Explanation:
1 Mile = 5280 Feet
260,000 Miles = 5280 × 260,000 Feet
260,000 Miles = 1,372,800,000 Feet
