Answer:
A. The spectrum shows a single electron in the 2p subshell.
Explanation:
(4.5 x 10^24 molecules) x (60.013 g / 6.022 x 10^23) = 448 grams or 4.484 x 10^2 grams = Answer
Answer:
None of the above
Explanation:
Work is defined as the force that moves an object through a particular distance:
Workdone = force x displacement
At constant velocity, the force on a body is zero because such a body is not accelerating.
Force is a product of mass and acceleration. Acceleration occurs only when velocity changes with time. If no change in velocity, acceleration does not occur. Therefore, no force is being applied.
From all the situations given, the condition is set at constant velocity. At constant velocity, there is no acceleration. This implies that no work is done.
Answer:
A lower ph is always more acidic, due to the increased concentration of hydrogen ions in the solution/substance.
A ph of 3 is 100 times more acidic than a pH of 5, and this is due to the increments on the scale.
