What is Newtons First law of motion?!
Every object in a state of uniform motion tends to remain in that state of motion unless an external force is applied to it.
100
The vertical columns of the periodic table are called?
groups
100
What is an element?
an element is, a pure substance that CAN NOT BE BROKEN DOWN; into simpler substances.
100
What is the order of the phases from the slowest molecular movement to the fastest molecular movement?
solid, liquid, gas
100
Which of the following variables is a vector, speed, time, distance, velocity and why?
velocity because it has a direction
200
What is Newtons Second Law of Motion?
The relationship between an object's mass m, its acceleration a, and the applied force F is F = ma. Acceleration and force are vectors (as indicated by their symbols being displayed in slant bold font); in this law the direction of the force vector is the same as the direction of the acceleration vector.

What is a compound?
a compound is made up of two or more types of elements; that are "CHEMICALLY" combined.

What is a gas?
An airlike fluid substance which expands freely to fill any space available, irrespective of its quantity.

If a persons mass is 60 kg on Earth, what is their weight?
60 Kg x 9.8 = 588 N

What is Newtons Third Law of Motion?!
For every action there is an equal and opposite reaction.

In the chemical formula CH4+O2 yields CO2+H2O what are the reactants and what are the product?
reactants-CH4 + O2 products- CO2 + H2O
300
What is a mixture?
a mixture is a substance made by mixing other substances; and they are combined together.
300
What is a solid?
it has a specific size and shape.

Which of the following is a form of thermal energy? rubber band, sound, batteries, fire
fire

What is the definition of, force?
is a push or pull upon an object resulting from the object's interaction with another object. Whenever there is an interaction between two objects, there is a force upon each of the objects. When the interaction ceases, the two objects no longer experience the force. Forces only exist as a result of an interaction.

Is the equation CH4 + O2 yields CO2 + H2O balanced? If not balance it.
No CH4 + 2 O2 yields CO2 + 2 H2O
