Two follow-up questions. What are the numbers out to the right of some of the equations? They look like a -1 and a -2 with a circle around them. The second question, and probably the most important...Why do we multiply equation 1  by 9?

Give an example of a ketone and state a common, well-known use or source for that same substance. 29. Use the down arrow on the far left of the row of icons above the space where you enter your answer to access the superscript "x2" function.   Write the symbol for the potassium ion

What I have Learned Activity 4: Match Me! A. Match column A with the description in column B. Write the letter of the correct answer before the number. Column A Column B 1. Motion 2. Velocity A. The object's motion has a constant speed. B. The length of the entire path of the object's motion. C. It is a change in position from the reference point. D. Refers to the rate of change in distance per 3. Distance 4. Displacement unit time E. The shortest distance between the object's two positions. F. A quantity which includes magnitude only. 5. Uniform Motion 6. Reference Point G. The frame of reference H. The speed of the object throughout its travel. I. A quantity which includes the magnitude 7. Scalar quantity 8. Vector quantity 9. Average Speed and direction. 10. Speed J. It is the rate of change in displacement.

Part II Graham's Law (average speed and molar mass) - Submicroscopic View Your observation 1. The speed of the particles is (circle one) a. Constant b. Variable C. same 2. The particles move in a between collisions. a. straight –line b. curved path 3. The speed of the particles changes following the collision with a. another particle b. the wall of the container c. both the wall of the container and another particle. Use the Track function explained earlier to help answer this question. 4. Collisions between particles or the walls of the container are elastic or not elastic. 5. The particles attractions to other particles. а. еxperience b. do not experience 6. The RMS speed of helium is as the mole of helium changes. a. constant b. variable 7. Record the RMS speeds of different gases in the following table. Table 1. RMS speed of gases Gas Не Ne Ar Molar mass g/mol RMS speed m/s 8. Is your observation of RMS speeds consistent the Graham's law of effusion, which states that rates of…

Step 2: Identify the dimensions of the quantities involved The second step is to identify the dimensions of the quantities involved in the problem. For example, if the problem involves distance, time, and velocity, the dimensions of these quantities would be length, time, and length/time, respectively. Step 3: Check if the units cancel out The third step is to check if the units cancel out. To do this, multiply the quantities together and check if the units cancel out, leaving only the desired unit. For example, if you are trying to find the velocity of an object and you know its distance and time, you can multiply distance by time to get velocity. If the units cancel out, you have a physically meaningful result. Step 4: Check if the result makes sense, to do this compare the units of the result with what you would expect based on the Robles statement.   Using the step hints above, answer the question. You do not have to solve. Just imagine that you're teaching a friend how…

If given a value that is plot along x-axis: 1. Find given value along x axis. 2. From this point, trace a straight line vertically (parallel to the y-axis) until it intersects with the line graph. 3. Then, trace a line horizontally (parallel to the x axis) from the intersect to the y-axis. 4. The value of y corresponding to the given x value is where the traced line intercepts with the y- axis. Based upon what you see in the graph listed below, estimate the cost of the fence installation. 450 350 A 300 4 250 200 150 100 50 10 151 20 25 30 35 Cost (in $)
