In order to change the pH from 3 to 6 you need to dilute the solution by adding water in it

As we can see that we are changing the pH by a factor of 3 that is we are diluting the solution by adding 1000 ml of water or you can say in general terms by diluting the solution 3 times.

Therefore in order to make the pH 6 you need to dilute the solution 3 times.

The sugar industry subsumes the production, processing and marketing of sugars (mostly saccharose and fructose). Globally, most sugar is extracted from sugar cane (~80 % predominantly in the tropics) and sugar beet (~ 20%, mostly in temperate climate like in the U.S. or Europe).  Sugar beets awaiting processing at the Holly Sugar Corporation plant near Brawley, California. Photograph by Environmental Protection Agency. (12/02/1970) Sugar is used for soft drinks, sweetened beverages, convenience foods, fast food, candy, confectionery, baked products, and other sweetened foods. Sugarcane is used in the distillation of rum. Sugar subsidies have driven market costs for sugar well below the cost of production. As of 2018, 3/4 of world sugar production was not traded on the open market. The global market for sugar and sweeteners was some $77.5 billion in 2012, with sugar comprising an almost 85% share, growing at a compound annual growth rate of 4.6%.[1] Globally in 2018, around 185 million tons of sugar was produced, led by India with 35.9 million tons, followed by Brazil and Thailand.[2] There are more than 123 sugar-producing countries, but only 30% of the produce is traded on the international market.

2. In the mouth, food is crushed into small particles through chewing and mixed with saliva, which contains amylase for digesting starch.

3. Food passes through the pharynx and oesophagus to reach the stomach. Gastric   juice  contains pepsin (for digesting proteins), HCl and mucus.

4. In the small intestine, carbohydrates, proteins and fats are completely digested into glucose, amino   acids, fatty acids and glycerol.

5. The villi of the small intestine absorb the digested food and supply it to every cell of the body.

Formulas used = 
1. Circumference = 2 pie r
2. Area of Quadrant = 1/4 Pie r
²


Circumference = 2 Pie r
                   22 =  2 * 22/7 r
                   r = 22 * 7 / 22 * 2
                   r = 7/2 or 3.5 cm

Area Of Quadrant = 1/4 Pie r²
                              = (1/4) * (22/7 ) * 3.5 * 3.5
                              = 1 * 22 * 35 * 35  /  4 * 7 * 10 * 10

He taught Science but did not like the subject himself. He was jealous of Crocker. He encouraged Taplow to say things against Crocker and mock at him. He tried to degrade Crocker at every point.

The young seagull was very hungry. It was this hunger that ultimately compelled and encouraged him to fly. When he saw his mother tearing at a piece of fish that lay at her feet, his hunger intensified .He cried and begged her to give him some food. When he saw her coming towards him with food in her beak, he screamed with joy and anticipation. However, she stopped midway. Not being able to resist his hunger any longer, he dived at the food in her beak. At that moment, his hunger overpowered his fear of the great expanse of sea beneath the cliff. Finally, this plunge was followed by the seagull's first flight.

My village is a perfect village, free from dirt. People have worked hard to make our village free from dirt. Earlier there was a lack of toilets in my village, but the toilets built under the government toilets campaign have made toilets in my village door-to-door, now no one in our village has to go to the toilets outside the fields etc.

A dustbin will be found in our village every 100 meters and no person litter the road. All the roads in our village are paved and adequate drains are made for the drainage of water, due to which there is neither mud nor water in our village. There is no municipality like system in our village for water, so we use hand pumps, but do not use wells and we have covered all the wells, so that mosquitoes etc. do not flourish.

The air in our village is clean, because we do not use petrol and diesel vehicles very much except for only a few tractors. We mostly use bicycles. Overall, the health of the people of our village is good, and there is no dirt at all in our village. In this way, my village is a dirt-free ideal village.

स्वच्छता व बेहतर स्वास्थ्य की दृष्टि से वातावरण को अनुकूल बनाने के लिए कई नवाचार किए जा रहे हैं। कोरोना के बढ़ते संक्रमण, संचारी रोग से बचाव व स्वच्छता के विकास को लेकर पेयजल एवं स्वच्छता विभाग जलशक्ति मंत्रालय द्वारा 8 से 15 अगस्त के बीच में ‘गंदगी मुक्त भारत’ अभियान सप्ताह चलाकर स्वच्छता को बढ़ावा दिया जा रहा है।

मेरा गाँव एक आदर्श गांव है, जो गंदगी से मुक्त है। गंदगी से मुक्त बनाने के लिये हमारे गाँव को लोगों ने बहुत मेहनत की है। पहले मेरे गाँव में शौचालयों का अभाव था, लेकिन सरकार शौचालय अभियान के तहत बनवाए गए शौचालयों से मेरे गाँव के घर-घर में आज शौचालय बन गए हैं अब हमारे गांव के किसी भी व्यक्ति को बाहर खेत आदि में शौचालय के लिए नहीं जाना पड़ता।

हमारे गाँव में हर 100 मीटर पर एक कूड़ेदान मिलेगा और कोई भी व्यक्ति सड़क पर कूड़ा नहीं डालता। हमारे गाँव की सारी सड़कें पक्की बनी हुई है तथा पानी के निकासी हेतु पर्याप्त नालियां बनी हुई है, जिससे बारिश में हमारे गांव में ना ही कीचड़ होता और ना ही पानी जमा होता है। पानी के लिये हमारे गाँव में कोई नगर पालिका जैसी व्यवस्था तो नही है, इसलिये हम लोग हैंडपंप का उपयोग करते है, लेकिन कुओं का उपयोग नही करते और सारे कुओं को हमने पाट दिया है, जिससे मच्छर आदि नही पनपते।

हमारे गाँव की हवा एकदम स्वच्छ है, क्योंकि केवल कुछेक ट्रैक्टरों को छोड़कर हम पेट्रोल-डीजल वाले वाहनों का ज्यादा उपयोग नही करते। हम लोग अधिकतक साईकिल का ही उपयोग करते हैं। कुल मिलाकर हमारा गाँव के लोगों का स्वास्थ्य अच्छा ही रहता है, और हमारे गाँव में गंदगी बि्ल्कुल नही है। इस तरह मेरा गाँव गंदगी मुक्त आदर्श गाँव है।

Gaurav Seth 5 years, 4 months ago

The given equations are: x + 6/y = 6 ……..(i) 

3x - 8/y = 5 ……..(ii) 

Putting 1/y = v, we get: 

x + 6v = 6 …….(iii) 

3x – 8v = 5 ……(iv) 

On multiplying (iii) by 4 and (iv) by 3, we get: 

4x + 24v = 24 ……..(v) 

9x – 24v = 15 ……..(vi) 

On adding (v) from (vi), we get: 

13x = 39 

⇒ x = 3 

On substituting x = 3 in (i), we get: 

3 + 6/y = 6 

⇒ 6/y = (6 – 3) = 3 

⇒ 3y = 6 

⇒ y = 2 

Hence, the required solution is x = 3 and y = 2.

The chemical symbol for oxygen is O, but pure oxygen exists as diatomic (“two-atom”) molecules, represented by the chemical formula O2. A molecule of the compound carbon dioxide consists of one atom of carbon and two atoms of oxygen, so carbon dioxide is represented by the chemical formula CO2.
