Sample Paper chemistry Class 11 1. 1.7 g of AgNO3 is dissolved in 100 g of water. 0.585g of NaCl dissolved in 100g of water is added to it and chemical reaction occurs. 1.435g of AgCl and 0.85 g of NaNO3 are formed. Justify that the data obey the law of conservation of mass 2. (a) When 4.2g of sodium bicarbonate is added to a solution of acetic acid weighing 10g‚ it is observed that 2.2g of CO2 is released into atmosphere. The residue is found to weigh 12g.

the hardest year in American history. People were suffering economically‚ people were dying of starvation‚ and unemployment had risen. During this era music and art describe the emotion of American people. Music gave people hope‚ like the song “God Bless America” written by Kate Smith.

Collision Lab Simulation Purpose: To study elastic and inelastic collisions in one-dimension. Background Information: Momentum: is a measure of mass in motion. It is the product of mass x velocity. Conservation of Momentum: in the absence of external forces‚ such as friction‚ the linear momentum of a system remains constant. Procedure: 1.

The collision of temperaments: The analysis of relationships between people with different physiologically determined temperaments An individual’s character can be determined by many factors. People learn behaviour from external factors like the environment they grow up in and by observing the people they interact with. Human behaviour is also impacted by the emotions people experience and the manner in which they express them. However‚ a theory from ancient times states that character is strictly

Simple 1D Collisions PhET Lab Introduction: When objects move‚ they have momentum. Momentum‚ p‚ is simply the product of an object’s mass (kg) and its velocity (m/s). The unit for momentum‚ p‚ is kgm/s. During a collision‚ an object’s momentum can be transferred to impulse‚ which is the product of force (N) and time (s) over which the force acts. This allows us to write the momentum-impulse theorem: Procedure: Play with the Sims Physics Motion Collision Lab Work with 1D collisions at this
