Answer:
hope this helps!
Explanation:
In a chemical change, the atoms in the reactants rearrange themselves and bond together differently to form one or more new products with different characteristics than the reactants. When a new substance is formed, the change is called a chemical change
Chemical changes occur when a substance combines with another to form a new substance, called chemical synthesis or, alternatively, chemical decomposition into two or more different substances. These processes are called chemical reactions and, in general, are not reversible except by further chemical reactions.
Using the line graph below, find the independent and dependent variables.
Answer:
The independent variable in on the x-axis, and the dependent variable is on the y-axis.
Explanation:
The independent variable belongs on the x-axis (horizontal line) of the graph and the dependent variable belongs on the y-axis (vertical line). The x and y axes cross at a point referred to as the origin, where the coordinates are (0,0).If you are confused, please check out this website talking more in-depth about graphing!

Answer this question and you’ll get 20 points Explain how energy is transfers using the major forms of energy in a circuit describe the energy source and form as energy is transformed throughout the circuit. Give at least 3 forms of energy. Including 2 transformations that occur. Make sure to provide the evidence that would indicate how we would know that the energy is complete within the circuit
Answer:
When the fuel is burnt, the hot gas rushes out of the rocket due to the great heat and pressure produced by the release of chemical energy in burning. Energy transfer is the movement of energy from one location to another. Energy transformation is when energy changes from one type to another.
Explanation:
Balance the given equation
2Cu + _____ = CuO + _____
Answer:
2Cu+2H20=2CuO+2H2
Timothy always liked playing catch with his dad. Whenever he had the chance to pick up a small object, he simultaneously threw a random object at his dad to catch him of guard. His objective was to have his dad drop the item. One day, Timothy threw two objects at is dad. One object was a tennis ball and the other was a golf ball. His dad ended up dropping both of the objects on the floor but was able to catch them after the drop because they both bounced back into his father’s hands. He wondered how this was possible???? This led to Timothy asking a science question that he would like to test by doing an experiment. What science question do you think Timothy asked to jumpstart an investigation?
THIS IS SCIENCE BTW BUT PLEASE HELP I WILL GIVE BRAINLIEST TO THE MOST ACCURATE AMSWER
