What was the condition assumed by Laplace In comecting Newton's equation for the velocity of sound in a gas? Write the Newton-Laplace equation.

Write the van der Waal's equation for 'n' moles of a real gas.

Potassium permanganate is a powerful oxidising agent in neutral, acidic and alkaline medium. In the lab, students were asked to convert an iodate. One of the students obtained I_2 instead of iodate:- What is the reaction carried out by the students who got iodate? Write the chemical equation.

While discussing the propagation of sound through atmospheric air,one argued that the velocity of sound is 280 ms^(-1) and said that he calculated it using Newton's formula.But another learner argued that velocity of sound is 330 ms^(-1) .He justified his arguement by saying that he has applied Laplace corrected formula. Write the formula used by the second learner.

State Newton's second law and arrive at the equation of force.

Derive the equation for force on the basis of Newton's second law.

While discussing the propagation of sound through atmospheric air,one argued that the velocity of sound is 280 ms^(-1) and said that he calculated it using Newton's formula.But another learner argued that velocity of sound is 330 ms^(-1) .He justified his arguement by saying that he has applied Laplace corrected formula. Using the above relation,show that velocity depends on temperature and humidity while is independent of pressure.

Write down the equation for the reaction between CuSO_4 ,and ironnail? What type of reaction is this?

A stone is thrown upwards from the ground with a velocity u . What is the maximum height attained by the ball? Check the correctness of the equation thus obtained using the method of dimensional analysis.
