Why do we need to conserve water |
|
Answer» Answer: Explanation: Clean, fresh water is a limited resource. With all the severe droughts happening in the world, the limited supply of fresh water is becoming one of our most precious resources. Every person on earth needs water to survive. Without it, many of us would get sick and even result in death. While almost 70% of the Earth is made up of water, many parts of the world suffer from clean water shortage. Conserving water is important because it keeps water pure and clean while protecting the environment. Conserving water means using our water supply wisely and be responsible. As every individual depends on water for livelihood, we must learn how to keep our limited supply of water pure and away from pollution. Keeping our water supply safe and pure will protect the water for the generations to come. Many believe that our water supply infinite. HOWEVER, our supply is quite the opposite. It is important that we must not pollute your water as many do not REALIZE just how important and scarce water is. Only 2% of the Earth’s fresh supply of water is locked in ice caps and glaciers, while 97,5% of the earth’s water is saltwater. Conserving water involves refraining from water pollution. This requires the use of strategies that includes reducing wastage, prevent damaging water quality, and improve water management. The population must save the water he has today and provide a sufficient supply for the next COMING years. Here are the REASONS why saving water is important: Hope u UNDERSTAND |

Chlo jaldi bolo 1.Difference between alcohol and acetic acid |
|
Answer» HELLO! ALCOHOLS are organic compounds that have -OH group as the main functional group. For example, ethanol (C₂H₅OH). Acids are the organic compounds that have -COOH group as the main functional group. For example, acetic acid (CH₃COOH). They are WEAKER than mineral acids, and aromatic acids have stronger acidic character than aliphatic acids. When an alcohol and an acid reacts in PRESENCE of concentrated sulphuric acid, an ester is produced, which is identified by its fruity smell. Hope this is enough, |
