Explanation:
nuclear fusion yields more energy than nuclear fission and the products of the reaction are not radioactive
Chlorofluorocarbons are a class of organic compounds that were used as propellants in the late 20th century. The problem with CFC's is that they attack the ozone layer, breaking it down. The weakened ozone layer is not able to stop UV light from reaching the earth, so the amount of UV light reaching the earth increases. This results in increased temperatures, and the death of vegetation.
Therefore, the answer is B.
The concept that can be used in order to determine the answer to this item is that of ratio and proportion. The ratio of the mass of the product to the sulfuric acid solution used in the first set should be proportional to that of the second. If we let x be the volume of the acid then, the equation that can be used is,
3.2 g / 4 L = 8 g / x L
The value of x from the equation is 10.
<em>ANSWER: 10 L</em>
Answer:
d. carboxyl
Explanation:
The presence of carbonyl group (>C=O)) and a hydroxyl group ( (−OH) on the same carbon atom is called a "carboxyl" group. A carboxyl group is represented as COOH and acts as the functional group part of carboxylic acids.
For example:
- Formic acid or Methanoic acid (H-COOH)
- Butanoic acid (C3H7-COOH)
Hence, the correct option is "d. carboxyl ".
