the graph shows the amount of a gaseous product formed over time during two trials of a reaction. a different concentration of a reactant was used during each trial while other factors were kept constant.
a graph is shown with two graph lines sloping upwards. the title on the x axis is time and the title on the y axis is amount of product. the graph line with a steeper slope is labeled trial 2 and the other is labeled trial 1.
which of the following statements explains which trial has a higher concentration of the reactant?
trial 1, because the final amount of product formed is higher.
trial 1, because this reaction lasted for a longer duration than trial 2.
trial 2, because this reaction was initially fast and slowed down later.
trial 2, because the amount of product formed per unit time is higher.

Imagine that a new planet is discovered with two moons of equal mass: moon a and moon b. the mass of the new planet is greater than the combined mass of its moons. moon a is farther away from the new planet than moon b. what is the planet's gravitational pull on moon a compared to the planet's gravitational pull on moon b? the planet's gravity repels moon a with a greater force than it repels moon b, which is why moon a is farther away. the gravitational pull on moon b is greater than on moon a because moon b is closer to the new planet than moon a. the gravitational pull on moon b is greater than on moon a because moon b is farther away from the new planet than moon a. the gravitational pull on moon a is the same as the gravitational pull on moon b because distance does not affect the planet's gravity.

High-pressure liquid chromatography (hplc) is a method used in chemistry and biochemistry to purify chemical substances. the pressures used in this procedure range from around 500 kilopascals (500,000 pa) to about 60,000 kpa (60,000,000 pa). it is often convenient to know the pressure in torr. if an hplc procedure is running at a pressure of 1.03×108 pa , what is its running pressure in torr?
