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%  ...

Why sleeping under the tree at night is dangerous ?


Please don't sleep under tree at night. It is quite harmful.



     See, during night you are not able to breathe properly, right?


Do you know why?

This is because during the day, in the presence of sunlight, plants takes in carbon dioxide and release oxygen in the process of photosynthesis.



That is why production of oxygen is more than the production of carbon dioxide during daytime. 

Hence, if we sleep under a tree during daytime, we may get a good amount of oxygen, thus giving us a nice sleep.


However, at night, plants do not perform photosynthesis due to the absence of sunlight. But respiration still goes on. 

Hence, as compared to oxygen, the proportion of carbon dioxide around the trees is more. It is not good for humans health. 


Thus, if we sleep under a tree at night, we may feel suffocated due to lack of oxygen.

Moreover, inhalation of excess carbon dioxide is harmful to human beings.


Therefore, it is not good to sleep under a tree at night.

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 elec...

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...

How do you prepare 1M or 1N hcl ?

±  How to make 1 Molar or 1 normal hcl In case of HCL molarity & Normality is same Because- Because HCL = H+ + CL-  HCL contain only one H+ ion means Basicity Of HCL is = n = 1  Normality = molarity  × n   n =  [Basicity of HCL ]  N= M×1   So  N = M (That is why in case of HCL Normality & molarity is same ) Now let's see how to make 1 N or 1M  HCL from 37% concentrated HCL This calculation varies with concentration of HCL. Because density varies with concentration of HCL . Now we are having density 1.18 for 37% concentrated HCL.  If you are going to use less concentrated HCL then first find out density of it then put that value in below formula instead of 1.18. HCL is liquid, so at first we need to convert HCL molecular weight (gm) into volume (ml) let's use formula density = mass / volume volume = mass of HCL   / density                           ...
