Dominic made the table below to organize his notes about mixtures. has no set composition,
must have more than one state of matter,
must have more than one substance.

What mistake did Dominic make?

The title should read “Properties of Solutions” because some mixtures do not have all of the properties listed.

There is a definite recipe to make each mixture, so the composition of a mixture is set.

Although it is possible to have more than one state, it is also possible to have only one state.

A single substance can be used to make a mixture if the substance is composed of more than one element.

- "the choice that is not an indicator of a chemical change is "state of matter changes". more common than not, chemical reactions produce energy in the form of light or heat. along with energy, they also produce a new substance called the product that could be in any state of matter (solid, gas, or liquid)."

i think its 100

i hope this !

(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
