First, have you gotten enough sleep? Lack of sleep is the Number One reason that human beings make mistakes when trying to concentrate or focus on activities or studies! Kids and teenagers need between 10 to 12 hours of sleep in one night to recharge their bodies and stay healthy - adults need 6-8 hours. If you're not getting enough sleep, it's time to decide what you need to cut out of your busy life so that you can be more healthy!
Next, make sure you start the day with a decent breakfastthat will provide fuel for your brain during the day. This means healthy food, not junk food full of sugar and caffeine - those will burn off in about an hour, leaving you even more tired and hungry than you were to start! Even if you do eat later in the day, missing this first meal sets up a train of events in the body that is hard to recover from. Learn about low GI eating habits which provide your body with fuel for the longest possible time and provide you with a consistent level of blood sugars. Symptoms such as trouble concentrating, feeling tired, and "zoning out" are typical of low blood sugar levels (NOTE: if you continue to have these problems even after eating a healthy mean, or if you have symptoms like excessive thirst or frequent urination, you need to see a doctor to check for Diabetes!).

Don't feel like concentrating? Are you putting off a task or project you're supposed to be working on? That's a form of procrastination. "
Different people have different ways of concentrating. Some like to listen to music while they work and others like silence. I suggest you find a quiet corner with good lighting and no distractions. Try not to let your mind wander beyond your work, because chances are, your imagination will take over. In your new "working corner" make a comfortable spot for yourself with pillows and blankets. You may even want to buy a beanbag or comfy chair. You can also sit at a table so you can lay all your things out and have a hard surface to work on. Another suggestion is going to a quiet coffee/donut shop and finding a nice table. You can even hunker down with some food/drink. It helps me to have something to munch on or sip while I work.
They concentration such as some people like to be in a room that is completely silent, some people cannot work without a noise in the background but overall if you have the TV or radio on make sure your back is the TV so you cannot watch it and try and listen to music without lyrics. And lastly sucking sweets or Chewing Gum has been proven to increase concentration, some times you may even be allowed to have sweets and gum in a test to help with the concentration. Don't ask me how but chewing and sucking helps the brain concentrate, as long as you are not distracting anyone else around you.
Choose a quiet room with no distractions. Create a task list and break it down into smaller parts. Focus on the tasks that are more difficult or giving you problems. Excersise your mind by doing other activities such as drawing. Challange your mind by meditating.
It all depends on the person, I usually have music going and everything else closed off from me; then focus on the task at hand. However, the commonly used technique is to have everything closed out, no external noises or attentions, then focus on the task.
Many people have found that SOFT music in the background does help them to concentrate. However, you DO need to turn off the cellphones, internet, Video Games, TV, and chat.
To concentrate mind in study do yoga and meditation . which only keeps our mind free without any other evils and helps us to concentrate to study well.
Increase the concentration of salt and acid or base. If you are not suppose to increase concentration use more volume of buffer.
Reaction rate increase when the concentration increase.
In a nutshell, yes. The water will go from a higher concentration to a lower concentration to increase the entropy of the lower concentration area. The increase in entropy of the lower concentration area would be greater than the loss of entropy of the higher concentration giving you a NET increase in total entropy.

As you increase the concentration of the solution, the concentration of H+ does not change. Meaning, the concentration ionized does not change. Just the original concentration increases. Since percent ionization = (concentration ionized)/(original concentration) , and the original concentration is increased, the percent ionization therefore decreases.
52.38% Increase
The reaction rate increase with reactants concentration.
Nothing
Because the concentration is directly proportional to the rate of reaction (the rate will increase but k will remain the same), with an increase in concentration the activation energy will stay because the activation energy does not account for the concentration.
Increase the concentration of SO2
pH is the negative logarithm of the hydrogen ion concentration; so an increase in hydrogen ion concentration give a reduction in pH. A reduction in hydrogen ion concentration causes an increase in pH.
After evaporation the concentration of salts increase.
