Answer:
Because time is independent of distance, and distance is dependent of time.
Explanation:
Usually, on any graph, the independent variable is plotted on the x-axis and the dependent variable is plotted on the y-axis. Because of this, time, which is independent (time happens regardless of any other factor), is on the x-axis while distance, which is the dependent variable (can only take place in time), is on the y-axis.
Answer:
25.5 g
Explanation:
First, you will need a balanced chemical equation
CuO + H₂ ==> H₂O + Cu
From the equation above, we can see that for every 1 mole of CuO (copper(II) oxide), 1 mole of Cu (copper) is produced.
Convert grams of CuO to moles. You should get 0.402 mol. Now with the relationship established above, you can see that you should ideally get 0.402 mol. Convert this to grams. Your answer should be 25.5 g.
P * V = n R T
<span>1 * 2.50 = n * 0.082 * 273 = 2. 50 / ( 0.082 * 273 ) = 0.11 mol </span>
<span>mass = mole number * molecular mass </span>
<span>mass = 0.11 * ( 16 * 2 ) = 3.52 g </span>
You have a. 3, b. 2, e. 6, f. 3, i. 1
Your answer might be Electromagnetism
