From the equation, we can see that the molar ratio between hydrogen and oxygen is:
2 : 1
Next, we determine the moles of hydrogen and oxygen that are actually present using:
moles = mass / Mr
Hydrogen:
moles = 4 / 2 = 2
Oxygen:
10/32 = 0.3125
Therefore, it is evident that the moles of oxygen present, 0.3125, are less than those that are required for 2 moles of hydrogen, which is 1. This makes oxygen the limiting reactant, which is the one that limits the completion of a reaction.

Answer:
Which observation provided Albert Einstein the clue that he needed to explain the photoelectric effect? Energy of electrons depends on light's frequency, not intensity. A change in which property of light will have no effect on whether or not the photoelectric effect occurs?
Explanation:
Answer:
Acceleration, rate at which velocity changes with time, in terms of both speed and direction. A point or an object moving in a straight line is accelerated if it speeds up or slows down. Motion on a circle is accelerated even if the speed is constant, because the direction is continually changing.
Time graph plots acceleration values on the y-axis, and time values on the x-axis. In this graph, the acceleration remains constant at 2.0 m/s/s for 10 seconds. Acceleration is defined as a change in an object's velocity, so if an object is accelerating at 2 m/s/s, then every 1 second, the object will gain 2 m/s.
