Car 1 and Car 2 have equal masses of 2,000 kg each. Car 1's initial momentum was 40,000 kg-m/s to the right: Car 2 wasn't moving.
• Car 1 collided with Car 2.
Car 1's final velocity is 10 m/s to the right; Car 2's final velocity is unknown
.
2. What is their total initial momentum? (4 points)

3. After the collision, what is Car 2's final velocity? (4 points)

4. What is their total final momentum? (3 points)

39 points and brainliest

answer: the value of enthalpy change will be -152.80 kj.

solution:

pressure = 1atm , temperature = = 298 k

given that pressure and temperature are same in both gases , the number of moles of both gases can be determined by the ideal gas equation.

according to reaction 3 moles no are reacting with 1 mol of ,then 0.49 mol of no will react with moles of ozone that is 0.16 moles of ozone. since, no is limiting reagent and is an excessive reagent.

enthalpy change for the reaction between the given volumes of the gases is :

a pan containing water is placed in a positio n where it is exposed to a 10 mile per hour wind. the pan contains a uniform depth of 1.27 cm of water, is quite wide, and has a length of 2.44 m in the wind direction. the water in the pan is at a constant temperature of 15.5 °c.

your answer is c) plasma
