You DO need to put them in order or the engine will not run properly. To find out the order we need make and engine size.

A solid might form from two solutions. A gas may be formed, which is indicated by bubbling. There might be a color change. There might be a change in temperature.
it would stay in place because the earth is its centripetal force and if it doesnt have the earth it wouldn't orbit
If you're even thinking of that you should of never became an adoptive parent in the first place. Because you can't do that. If the child is acting up then maybe they're not happy. You might want to change that.
There are many observations that may occur when a chemical reaction takes place. Some of the things are:- Change of colour, change of temperature change of state. These can be observed by the features below There might be a change in colour when mixing the reactants; the vessel in which the reaction is taking place might get warm on the outside or cold depending on the type of reaction. There may be effervescence or fizzing with gas production; a precipitate may form.

A change in an organism that takes place over time is called an adaptation. An adaptation happens when an organism needs to change in order to survive.
Any force acting on an object will cause an acceleration. An acceleration implies a change in velocity. To be more precise, acceleration is the rate of change (dv/dt, which is basically change in velocity divided by time). There has to be a NET FORCE - for example, it is possible that you pull or push something, but that there is enough frictional force (acting in the opposite direction to the pull or push) to keep counteract your force, and keep the object in place.
You might observe a change in color, gas bubbles being formed, a change in temperature (this might require the use of a thermometer, unless the solution actually boils), or you can test for a specific chemical by using an indicator, or analyse the solution by means of a mass spectrometer. Explosions are also a very convincing form of evidence that a chemical change has taken place.

That is officially called the activation energy.
