Probably I got it wrong....but, E/m represent the ratio between charge and mass of the electron. The value of E/m is the result of the famous experience carried out by J. J. Thomson to detect …

The mass of the positive ion of element X deposited at cathode on passing 2F of electricity is 30g. So the number of moles of ions deposited is 30/45=2/3mol, where atomic mass of X is 45g"/" …

See the explanation below The overall reation is Cu^ (2+) +Sn rarr Cu +Sn ^ (2+) At the positive electrode, the reaction is Cu^ (2+)+2e^ (-) rarr Cu At the negative electrode, the reaction is Sn …

2. If the figure to the right shows the reflected ray from the mirror. Which one of the figures below shows the incident ray? Show that the points (-1,4,-3) , (3,2,-5) , (-3,8,-5) and (-3,2,1) are …

The Plum Pudding model stated that atoms are positive spheres with randomly placed negative Electrons. By defining the location of the positive and negative charges, this model was easily …

Without diving into complexities of Medieval rulership, borders and land ownership (let alone how these still relate to recent territorial issues), Poland survived, despite many engagements with …

Um, no. Pressure decreases with increasing volume. A positive slope of a pressure P vs. temperature T graph suggests that P increases with increasing T. A positive slope of a volume …

If the temperature is higher then the rate of reaction increases Unsaturated hydrocarbons will burn with soty flames Energy density of a compound is dependent on the number of carbon atoms …

I have conducted a calorimetry experiment on the latent fusion heat of ice. Even when the procedure is followed throughly, I keep getting a value that is far off from the actual value. And …
