How to make 1N and 1M H2SO4 ?

Now let's see how to make 1 N and 1M  H2SO4 from 98% concentrated H2SO4 . This calculation varies with concentration of H2SO4. Because density varies with concentration of H2SO4 . Now we are having density 1.84 for 98% concentrated H2SO4.  If you are going to use less concentrated H2SO4 then first find out density of it then put that value in below formula instead of 1.84 H2SO4 is liquid, so at first we need to convert H2SO4 molecular weight (gm) into volume (ml) let's use formula density = mass / volume volume = mass of HCl  / density                             98.08 / 1.84 V = 53.30 ml Here we are making 1M and 1N  H2SO4 from 98% concentrated H2SO4. If you are going to use less concentrated H2SO4 then use that percentage value in below formula rather than 98%. Let's use formula  1M H2SO4 (98%) =  53.30 ml [ V ]                100%    ...

Importance of vitamins and their sources

 Vitamins are micronutrients which help perform important functions in our body. The most essential vitamins needed by our body are vitamin A, C, D, E, K and a group of B-complex vitamins.



Vitamin A is required to make a pigment called Rhodopsin in our eyes. Rhodopsin helps us to see in low light conditions. Thus, without vitamin A, rhodopsin won't be produced, causing night-blindness.

Source of vitamin A : yellow, red and green (leafy) vegetables, such as spinach, carrots, sweet potatoes and red peppers. yellow fruit, such as mango, papaya and apricots.



Vitamin C and E are antioxidants. Unstable free radicals damage our cell's DNA, leading to illness or cancer. Vitamin C and E neutralize the free radicals, preventing cell damage.

Source of vitamin C and E :

Citrus Fruits. Raw citrus fruits are very high in vitamin C....


• Broccoli....

• Red Cabbage....

• Kiwi....

• Bell Peppers.


Vitamin D helps our body to  absorb calcium to build strong bones. Thus, lack of vitamin D can lead to a condition called rickets which is characterized by weak, soft bones. And if you have cholesterol problems then your body must be lacking of vitaminD 


Source of vitamin D :

Sunshine is best option for vitamin D . Whenever you get chance just expose your whole body to Sunshine in the morning or evening . Actually we don't get vitamin D directly from sunlight . It's just like photosynthesis process.  whenever our body make contact with morning or evening sunlight,  it Convert cholesterol which is already been in our skin into vitamin D.  



During an injury, vitamin K helps to prevent blood clot, as well as excessive bleeding.

Source of vitamin K : 

Green leafy vegetables including collard and turnip greens, kale, spinach, broccoli, Brussels sprouts, cabbage, lettuces.Soybean and canola oil.Salad dressings made with soybean or canola oil.Fortified meal replacement shakes.


Lastly, B-complex vitamins are essential for healthy functioning of our brain and nervous system.


These are some symptoms of lack of vitamin B complex 

  • extreme tiredness (fatigue)


  •  lack of energy (lethargy)

  • breathlessness.

  •  feeling faint.

  •  headaches.

  •  pale skin.

  •  noticeable heartbeats (palpitations)

Source of B complex vitamins : 


of B vitamins include meat (especially liver), seafood, poultry, eggs, dairy products, legumes, leafy greens, seeds and fortified foods, such as breakfast cereal and nutritional yeast.

Why Birds don't get Electrocuted on Power Cables?

        E lectricity is the flow of electrons through conductors. It always takes the easiest route, i.e., electricity always flows through a path of least resistance.      electricity flows are made of copper. Copper offers least resistance and is a very good conductor of electricity. However, the bird's body offers greater resistance and is not a good conductor as copper. Hence, electricity ignores the bird and flows through the cables and birds don't get electrocuted.      B esides this, electricity flows from its highest potential to its lowest potential. Now, the power cables usually run at different potentials. If bird's feet are on the same power cable, then they are at same potential. Thus, the bird doesn't get electrocuted. However, when the bird touches two cables with different potentials at the same time, then electricity will flow through the bird to go to the other cable with lower potential and the bird will get electrocut...

HOW CAN ANIMALS AND BIRDS SEE IN DARK ?

    Almost all animals and birds can see in dark. But humans cann't  see in dark or in night clearly. Just because of that ability to see in dark, some animals and birds can servive easily in this word ( owls). We all know they can see during day too, but ability to see in the dark make them special than humans.     Let's see how they can see in the dark .   The animals which can see in dark called as nocturnal animals. Nocturnal means ability to see in the dark. They can see in the dark just because of there eyes structure. Nocturnal animals eye contain specific rods cells that carry rhodopsin in the eyes that helps in the night vision. that rhodopsin are very sensitive to longer red wavelength.         Retina is the composition of rods and cones. Rods are not able to capture light as sharply as cones do. but That rods are very sensitive to low light level and hence responsible for the vision in night. Different animals have d...

Why is excess sugar dangerous for humans health ?

   If we consume a lot of sugar, then it can lead to serious health problems. For example: Image of sugar  A hormone called leptin tells our brain when to stop eating. However, consuming excess fructose which is a type of sugar can cause leptin resistance, a condition in which our brain does not respond to leptin. Hence, we overeat, resulting in obesity. Moreover, excess sugar is converted into a type of fat called triglycerides. Triglycerides can enter the bloodstream and form fatty deposits or plaques in blood vessels, increasing the risk of heart attack and stroke etc.  Image of heart attack  Excess sugar can even bind to collagen and elastin in our skin, damaging them and thus, making our skin saggy and wrinkly. Image of saggy and wrinkly skin .   Studies have also shown that women who have one or more sugary drinks per day are more likely to develop diabetes. Image of sugary drink. That's why  we need to stop consuming excess  sugar than...
