An unknown was tested using a procedure similar to the one for this experiment. It was found to contain Co and Pb ions. What does this suggest about the painting? Hint: Refer to the Pigment Handbook on page 112 of your lab manual for additional assistance on this question. Group of answer choices The painting is a forgery based on the composition of the blue (Cobalt Blue) pigment. The painting is a forgery based on the composition of BOTH the white (Lead White) and blue (Cobalt Blue) pigments. The painting could be authentic based on the composition of the white (Lead White) and blue (Cobalt Blue) pigments. The painting is a forgery based on the composition of the white (Lead White) pigment.

answer: i have one answer

acids are substances that ionize (break off) in an aqueous solution to produce hydrogen (h+) ions

explanation:

hope this and sorry i could only come up with one answer!

(newtons first law)

conservation of momentum law states :

momentum before collision = momentum after collision

momentum p (kg-m/s)= mass * velocity

say moving car=1 000 kg, velocity = 10 m/s then p = 1 000*10= 10 000 kg-m/s

say still car = 2 000 kg, velocity = 0 m/s then p = 2 000* 0 = 0 kg-m/s

total momentum prior to collision = 10 000 + 0 = 10 000 kg-m/s

momentum after collision = 10 000 kg-m/s

mass now = 1 000 kg+2 000 kg = 3 000 kg

10 000 = 3 000 kg* velocity m/s

10 000/3 000 = velocity

3.33 m/s = velocity after collision

an impulse is a force applied over time , momentum is exclusive of external forces and a perfect collision is implied
