(1)k=(H➕)2の2ってH2S→←2H➕➕S2-の2H➕の2を後ろに持ってきて(H➕)2となるのですか? (2)ともに0.10mol/Lの次の文です。なんで沈殿しないと分かるのですか? 教えてください。お願いします。

In one study on the breakfast babits of 1.600 young people Julete, vitamin C, iron and calcium, was better in those who had breakfast in the U, researchers found that the fire and micronutrient intale, including of regularly. There have been sämiäer finelings in Australia, Brazil, Canada and the Breakfast is also associated with improved brain function, including concentration and language. A review of 54 studies found that eating breakfast can improve memory, though the effects on other brain functions were inconclusive. However, one of the review's researchers, Mary Beth Spitznagel says there is "reasonable" evidence breakfast does improve concentration-there just needs to be more research. "Looking at studies that tested concentration, the number of studies showing a benefit was exactly the same as the number that found no benefit," she says. "And no studies found that eating breakfast was bad for concentration." What's most important, some argue, is what we eat for breakfast. High-protein breakfasts have been found particularly effective in reducing food fravings and consumption later in the day, according to research by the Australian Commonwealth Scientific and Industrial Research Organisation. While cereal remains a firm favourite among breakfast consumers in the UK and US, a recent Which? investigation into the sugar content of 'adult' breakfast cereals found that some cereals contain more than three quarters of the recommended daily amount of free sugars in each portion, and sugar was the second or third highest ingredient in seven out of 10 flaked cereals. 5)PV But some research suggests if we're going to eat sugary foods, it's best to do it early. One study found that changing levels of the appetite hormone leptin in the body throughout the day coincide with having our lowest threshold for sweet food in the morning, while scientists from Tel Aviv University have found that hunger is best regulated in the morning. They recruited 200 obese adults to take part in a 16-week-long diet, where half added dessert to their breakfast, and half didn't. Those who added dessert lost an average of 40 lbs (18 kg) more-however, the study was unable to show the long-term effects.
