larger and most of the time the red + cable is connected to the + post.
On the battery. Normally marked + and - but the round tapered post that is bigger diameter is positive. Some newer cars have a positive and negative post remote from the battery for jump starting because battery is not easily accessed.
Metals form positive ions because they easily lose their electrons.
because the components are easily seen through the solvent :)
You can easily touch both the positive and negative terminals of a 9V battery to your tongue. This is much harder to do with other batteries.
it is calcium concretions. It is easily seen from a radiograph and radiologists use it as a landmark because it is easily identified.
Obsidian. It commonly is dark because of the Fe contamination.
I doubt it but I am not 100% sure. It is unlikely in 1983 BMW was using a positive ground system. You can easily find out. Trace the negative battery cable and see where it goes. It is is attached to ground then it is a negative ground system.
Very Easily.
A mixture in which different materials are easily identified is known as a heterogeneous mixture. Its different components are easily identifiable due to its lack of a uniform composition.
Crystals are easy to classify because the minerals that they contain are easily identified. One example of this would be emeralds. Another example of a crystal is a diamond.
easily
because when we know the setting time of cement we easily identified that where can we use the cement according to there setting time.
