Calculate the number of molecule in 5g of steam​

Answer»

ergy required for5gm of water at 0 ∘ Cto get converted to water at 100 ∘ C is latent HEAT required + heat required to change its TEMPERATURE by 100 ∘ =(80⋅5)+(5⋅1⋅100)=900calories.Now,heat liberated by 5gm of steam at 100 ∘ C to get converted to water at 100 ∘ C is 5⋅537=2685 caloriesSo,heat energy is ENOUGH for 5gm of ice to get converted to 5gm of water at 100 ∘ CSO,only 900 calories of heat energy will be liberated by steam,so amount of steam that will be converted to water at the same temperature is 900537=1.66gSo,the final temperature of the mixture will be 100 ∘ C

Calculate the radius of first orbit of hydrogen atom and helium ion. Which one has smaller radius?give reason

Answer»

As the orbit is not a circle, there is no RADIUS. What you can calculate is the distance to the nucleus where the probability density to find the electron is highest, or you can calculate the expectation value for the distance.By accident, the most probable distance is very NEARLY the same as Bohr’s radius. Bohr ‘s value is 0.529 177 210 67(12) E-10 m.The expectation value is 1.5 times higher. But you can find the electron even at 5 times that distance with significant probability.For the He+ ion, you can just divide everything by Z = 2.

प्रूफ दैट हाथ पीरियड ऑफ़ जीरो ऑर्डर रिएक्शन इज प्रोपोर्शनल टो इनिशियल कंसंट्रेशन ऑफ reactant​

Answer»

DonateIn some reactions, the rate is apparently independent of the reactant concentration. The RATES of these zero-order reactions do not vary with increasing nor decreasing reactants concentrations. This means that the rate of the REACTION is equal to the rate constant, k , of that reaction. This property differs from both first-order reactions and second-order reactions.Origin of Zero Order KineticsZero-order kinetics is always an artifact of the conditions under which the reaction is carried out. For this reason, reactions that follow zero-order kinetics are often referred to as pseudo-zero-order reactions. Clearly, a zero-order PROCESS cannot continue after a reactant has been exhausted. Just before this POINT is reached, the reaction will revert to another rate LAW instead of falling directly to zero as depicted at the upper left.There are two general conditions that can give rise to zero-order rates:Only a small fraction of the reactant molecules are in a location or state in which they are able to react, and this fraction is continually replenished from the larger pool.When two or more reactants are involved, the concentrations of some are much greater than those of othersThis situation commonly occurs when a reaction is catalyzed by attachment to a solid surface (heterogeneous catalysis) or to an enzyme.
