Carbon is considered this
Element
This is what the law of conservation of mass states.
matter cannot be created or destroyed (what goes in, must come out).
The speeding up, slowing down or changing direction of an object
acceleration
This is what Newtons First Law of Motion states.
Object in motion remain in motion and objects at rest will remain at rest unless an unbalanced force acts on it
This is the formula for calculating speed.
Speed = Distance / Time
A house salad is considered this
Mixture
This is the REACTANTS in the equation below.
HgO ----> Hg + O2
HgO
The total amount of force acting on an object
Net force
This is what Newton's 3rd Law of Motion states.
For every action there is an equal and opposite reaction
This is what Velocity is.
speed in with direction
Oxygen is considered this
Element
This is how many grams sulfur needs to follow the law of conservation of mass.
Fe + S --> FeS
75g + ___G --> 250g
175g
The relationship between Force Acceleration and Mass

Answer may vary
This is the speed of a sprinter who ran 200 meters in 20 seconds.
10 m/s
Carbon Dioxide is considered this
Compound
According to the law of conservation of mass, this is how many grams of magnesium that are needed for the following chemical equation:
4Mg + 2O2 --> 4MgO
__g + 175g --> 500g
325g
If one person is pulling a rope to the left with 1000N Force and another person is pulling to the right with 2000N Force, this is the net force and direction the rope will move.
1000N to the right
Explain how your backpack laying on the floor applies to newtons 3rd law of motion

A car is speeding up to get onto a freeway, this is an example of this (think speed, velocity or acceleration)
acceleration
Rust is considered this
Compound
Determine whether the following is balanced or unbalanced (Show your inventory)
2AgNO3 + Cu --> Cu(NO3)2 + 2Ag
balanced
Ag = 2 both sides
N = 2 both sides
O = 6 both sides
Cu = 1 both sides
A mass of 500Kg is increasing it's speed at a rate of 20 m/s2. This is the force at
10,000N
