Answer:
Concept: Chemical Analysis
- You need to start by graphing the data and then analyzing it.
- We can see that the horse has a distance in meters of 980 at the end of the 10 seconds hence it is the fastest.
- The horse line has a linearly representation, while the alternate line has parabolic tendencies towards the end. The steeper line indicates a faster change in time or velocity which results in a greater distance traveled indicating that the horse is faster.
- *I have confidence you can graph that*
The answer is (3) pH 3 to pH 1. The pH is related to the concentration of H3O+ with the relationship: pH = -lg c(H+). So when concentration of H3O+ increase, the pH will decrease. And decrease 2 when when increase hundredfold. Because 100=10^2.
The study of metals and the process for refining and making things from them is called metallurgy.
Metallurgy is said to be the scientific study both of the extraction and refining process of metals from their ores.
This process includes steps such as grinding of the ore also called ore pulverization.
Ore is crushed to increase its surface area for purpose of increasing the level of its reactivity.
Sometimes, the ore is heated in the presence of oxygen to turn the ore into and oxide. This process is known as roasting.
Answer:
A
Explanation:
I believe the answer is A. An object is every color except the color we see, or the color that bounces off of said object. Therefore if a carpet is yellow, the carpet is every color but yellow. Yellow is the color that it rejects, bounces off of it, and the one we see.
The answer is conductors
