Answer:
In the forward direction and releases carbondioxide gas from backside.
Explanation:
In the forward direction and the carbondioxide gas which is a waste material is removed from the engine at the back. The chemical energy of fuel is converted into mechanical energy with the help of engine which able the car to move in the forward direction so engine is the key component that is responsible for the movement of car.
The two magnets ought to join together given that at least, if not both, have a strong enough magnetic force to do so.
If my memory serves me well, the following element which has the most properties in common with iron (Fe) is definitely <span>Osmium (Os) because they are stand for the same group!
I'm sure it helps!</span>
5. B air is a mixture of many elements, but is not a chemically fused.
6. B Beef stew, composition varies throughout.
7. A. They can be chemically separated into their component elements, but they are all homogenous, and as such, have constant composition, which differs from the components properties, as the components must undergo a chemical change to become compounds.
Let's use the example: H2O ---> H2 + O2
We find how many elements of a product are on one side and how many elements on the other side.
Reactant: H=2 O=1
Product: H=2 O=2
We need to make the same amount of hydrogen and oxegyn atoms on each side, regardless of how high the numbers are, and we do this by adding coefficients to the compounds.
Reactant: H=4 O=2
Product : H=4 O=2
2 H2O---> 2 H2 + O2
