You kind of need to show more, but the independent variable would be something that you are changing to then measure the reaction, like the time left in for example.
Answer:
26.981539 u
Explanation:
One mole of Al atoms has a mass in grams that is numerically equivalent to the atomic mass of aluminum. The periodic table shows that the atomic mass (rounded to two decimal points) of Al is 26.98, so 1 mol of Al atoms has a mass of 26.98 g.
Answer:
C. Tip had the lower pressure, it was 652.71mmHg
Explanation:
To answer this question you need to convert both values into a common unit so you can compare directly.
87kPa = 652.71 mmHg
The atomic radius decreases
Heat flows from hot to cold, therefore heat, denoted as q would flow from beaker A into beaker B
