The rate of a standard reaction is 0.01840 M/s at 25 oC. It is determined that this is too fast, and that the rate should be red

uced to 0.0046 M/s. What temperature should the reaction be run at to achieve this? A. 45 oC B. 20 oC C. 15 oC D. 5 oC E. 0 oC

Answer:

Option B. 20 oC

Explanation:

Thinking process:

The initial reaction takes place at: 0.01840 M/s at 25 oC.

However, the rate must be reduced to 0.0046 M/s.

It is most likely that a temperature of 20 °C is used her. This is because it offers sufficient kinetic energy to effect the reaction rate of the reaction substances.

If the measured gas pressure in a collection flask during a gas-forming reaction was determined to be 1.44 atm? If the measured
ryzh [129]
With the information given most likely in order to find the partial pressure of the gas produced you have to subtract the total air pressure in the collection flask by the atmospheric pressure since you assume that the flask started with atmospheric pressure when it was sealed and then the gas was added as the reaction took place increasing the pressure.
1.44atm-0.95 atm=0.49atm

Why is it essential for a calorimetry to be an insulated (closed) system?
aksik [14]

Answer:

B.Thermal insulation minimizes energy loses to the atmosphere.

Explanation:

It is important because it helps to stop hit from transferring from the calorimeter to the environment. This would help to have an accurate measurement of the heat that was used in the chemical process. The greatest cause of error that happens in calorimetry is when heat is lost to the environment. To reduce this, you insulate the calorimeter and add a cover.

What does conserving mass mean in a chemical equation?
lubasha [3.4K]
The law of conservation of mass states that mass or matter cannot be created or destroyed, only transferred or recombined.
For chemical equations, this law means that each element must be accounted for equally both for reactants and products. So the same numbers of each atom must match on each side, hence the necessity for balancing the chemical equation accurately. This created a field of chemistry called Stoichiometry, which accounts for the conservation of matter throughout chemical reactions and processes.
