With what you have here, there is no way to determine the volume. Do you have the density also?
Answer: A. AB + C → AC + B
Explanation:
A single displacement reaction is also known as single replacement reaction. A reaction in which an element replaces another element from the compound is known as single displacement reaction.
AB + C → AC + B
Here, element C replaces another element B from compound AB.
Thus, option A represents is a general equation for a single displacement reaction
Option B represents a double displacement reaction where one element of a compound replaces another element of another compound and vice-versa, option C is a synthesis reaction where two reactants or more combine to form one product. Option D is a decomposition reaction in which multiple products are formed from a single reactant.
Answer:
V= 125volts
Explanation:
R =25ohms
I = 5 amp
V = ?
t = 36seconds
V = IR
V = 5× 25
V= 125volts
Q = It
Q = 5×36
Q = 180 coulombs
Q is the amount of charge.
I believe that you forgot to add the choices. However, I will just tell you what is the process of scientific inquiry and you can choose the best match from the choices you have.
Scientific inquiry is mainly the process of developing a meaningful explanation to a certain phenomenon or a question from the natural world. This process involves collecting data, forming a hypothesis and testing the results of this hypothesis. These results whether confirm or reject the hypothesis you made you made.
Scientific inquiry has seven main sub-process, these processes are as follows:
1- Figuring out the problem through observation
2- To do some research to gather more information about the problem and how to solve it
3- To develop your hypothesis on how to solve this problem
4- To test your hypothesis through experiments and observation
5- analyzing the results of your testing through graphs, tables, organizing data,....elc
6- to draw a conclusion based on these results. The conclusion will either confirm or reject your hypothesis
7- Just pass-on your results
Answer: 784 J
Explanation:
Potential energy is expressed in:
PE= mgh
= 2 kg x 9.8 m/s² x 40 m
= 784 J
