Finding Rates
This is the rate of a reaction that has produced 40 mL of gas in 20 seconds.
What is 2 mL/s?
This is what happens to the rate when powdered calcium carbonate is used instead of calcium carbonate chips.
What is increased?
This is the definition of concentration.
What is the amount of solute dissolved per unit volume of solution? (or something similar)
This is the element with the symbol At.
What is Astatine?
This is the name of the protagonist of the 2025 sequel to the Australian-made game Hollow Knight.
Who is Hornet?
This is the rate of the faster reaction out of the two reactions below:
A: Loses 45g in 27 seconds
B: Loses 90g in 55 seconds
What is 1.67 g/s?
These are the two reasons why increasing temperature generally increases the reaction rate.
What are particles have more kinetic energy for successful collisions and more frequent collisions?
This is the concentration of 2 mol of bicarb soda dissolved in 4 L of water.
What is 0.5M?
This is the chemical symbol for an element with an atomic mass of 63 amu and 32 neutrons.
What is Ga?
This is the name of the original purple Wiggle, who had a habit of always falling asleep in the middle of the show.
Who is Jeff?
The concentration of products in a solution is 0.8M after 5 seconds and 1.3M after 15 seconds. This is the average rate between 5 and 15 seconds.
What is 0.05 M/sec?
This is the one thing that all catalysts do when added to an appropriate reaction.
What is lower the activation energy?
This is the concentration of 5 g of table salt (NaCl) dissolved in 250 mL of water.
What is 0.34M?
This is the person who discovered the nucleus.
Who is Rutherford?
This spice is made from the dried stigmas of a flower and is one of the most expensive spices in the world
What is saffron?
This is the 10 second interval in which the reaction below is the fastest:
Time (sec): 0 | 10 | 20 | 30 |
Volume (L): 0.01 | 0.05 | 0.08 | 0.10
What is 0 – 10 seconds?
This is the reason why increasing the concentration of a reactant typically increases the rate of the reaction
What are more frequent collisions?
This is the mass of sucrose (C12H22O11) required to make 2L of 5M stock solution.
What is 3422.96 g?
This is the balanced equation for the reaction between magnesium metal and oxygen gas, producing magnesium oxide (MgO).
What is 2Mg + O2 → 2MgO?
This is the world's largest landlocked country.
What is Kazakhstan?
This is the rate on the graph between 10 and 15 seconds
What is 0.4 cm3/s (±0.1)?
This is the impact decreasing the pressure has on the rate of a gaseous reaction.
What is decrease
This is the volume of 8.78M HCl required to make 1.3L of 0.3M solution.
What is 0.044L or 44mL?
This is the only letter that has never appeared on the periodic table.
What is J?
This author created two of the most fully developed fictional languages ever (Quenya and Sindarin) for their fantasy world.
