Answer:

B. Point D and E

Explanation:

Kinetic energy is the energy of motion and is proportional to velocity of the object and its mass. Mathematically,

K.E=\frac{1}{2} mv^2

where m is mass of object and v is the velocity of the object.The object while moving upwards, starts with a high initial velocity ,thus high kinetic energy. The kinetic energy starts to reduce at point B and its minimum at point C.Potential energy is the energy of an object related to its position. Mathematically,

P.E=mgh

where m is mass of object , h is the height of the object and g is acceleration due to gravity. At point C the potential energy is maximum due to the height attained by the object.As the object falls, the potential energy starts to reduce at point D and reaches its minimum value at point E where all potential energy is converted back to Kinetic energy.

Chemical reactions can be detected by precipitation of a _____ from a solution.
RideAnS [48]

Answer: solid

Explanation: Chemical reactions are those which involve rearrangement of atoms.

Chemical changes are accompanied by following changes:

1) Absorption or release of heat

2) Change in color

3) Formation of gas bubbles

4) Formation of a solid product called as precipitate

Example of formation of precipitate or solid in chemical reaction:2AgNO_3(aq)+BaCl_2(aq)\rightarrow 2AgCl(s)+Ba(NO_3)_2(aq)

A 75.0 g sample of dinitrogen monoxide is confined in a 3.q L vessel. What is the pressure( in atm) at 115 celsius
Nonamiya [84]
Data Given:
                  Pressure  =  P  =  ?

                  Volume  =  V  =  3.0 L

                  Temperature  =  T  =  115 °C + 273  =  388 K

                  Mass  =  m  =  75.0 g

                  M.mass  =  M  =  44 g/mol

Solution:
              Let suppose the Gas is acting Ideally. Then According to Ideal Gas Equation,
                                      P V  =  n R T
Solving for P,
                                      P  =  n R T / V      ------ (1)
Calculating Moles,
                                      n  =  m / M

                                      n  =  75.0 g / 44 g.mol⁻¹

                                      n  =  1.704 mol

Putting Values in Eq. 1,

                    P  =  (1.704 mol × 0.08205 atm.L.mol⁻¹.K⁻¹ × 388 K) ÷ 3.0 L

                    P  =  18.08 atm
