Fe + heat ----> Fe_54 + + neutrons
Answer:
the correct choice would be: 4. Reaction rates are not related to spontaneity.
Explanation:
The speed of reaction is independent of spontaneity, since it depends on other factors such as the amount of reagent.
The amount of reagent is one of the variables that most influences the speed of reaction, the greater the amount of reagent, the faster the reaction will be and thus the speed will be increased.
Because they could have an explosive reaction and could possibly hurt you
Smashing a rock is the right answer :)
Answer:
32.6 %
Explanation:
Given data
- Mass of sucrose (solute): 22.8 grams
- Mass of water (solvent): 47.1 grams
Step 1: Calculate the mass of the solution
The mass of the solution is equal to the sum of the mass of the solute and the mass of the solvent.
m(solution) = m(solute) + m(solvent)
m(solution) = 22.8 g + 47.1 g
m(solution) = 69.9 g
Step 2: Calculate the percent-by-mass of sucrose in the solution
We will use the following expression.
