Answer:
A
Explanation:
mole=mass of the element ÷ atomic mass of the element.
mole=6÷atomic mass of flourine.
The step at A correctly converts 6 grams of fluorine to an equivalent number of moles of fluorine. That is "Divide 6 by the atomic mass of fluorine".
What is one mole of a substance?A mole is defined as the mass of the substance which consists of an equal quantity of basic units.One mole of any substance is equal to the value of 6.023 x [tex]10^2^3[/tex] (Avagadro number). It can be used to measure the products obtained from the chemical reaction. The unit is denoted by mol.The formula for the number of moles formula is expressed as the number of moles of the substance = mass of the substance/ mass of one mole of the substanceHow to calculate the number of moles of fluorine equivalent to 6 grams of fluorine?Given that,
The mass of fluorine = 6 grams
The atomic mass of one mole of fluorine = 18.99
So, the number of moles of 6 grams of fluorine= [tex]\frac{6}{18.99}[/tex]
Therefore, the step is given in option A: "Divide 6 by the atomic mass of fluorine" is the correct step that converts the 6 grams of fluorine to an equivalent number of moles of fluorine.

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.

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?

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!
