Answer: The student’s percent error is 3.16%.
Explanation:
Calculated mass of the block = 16.3 g
Actual mass of the block = 15.8 g
The student’s percent error is 3.16%.
Answer:
different reactants
Explanation:
because if you think about it what's really thick and it takes a lot longer to burn a piece of paper is super fit material which can just tear real easily just by ripping it with your fingers so if you think about it how fast it burns it's not how big the molecules are because paper has smaller molecules than wood would so the paper burns faster in differently so it's probably the reactant it's made of
Answer:
the answer is (2.54cm in an inch, and 4 number of choices in this question)
Explanation:
An exact number is not rounded, and cannot be changed such as placing a different item on the scale it would change.
The product will not be affected by the addition of twice as much Na₂CO₃.
<h3>What is Limiting reagent in stoichiometry ?</h3>
- The maximum quantity of the end product determined by a balanced chemical equation is known as the Stoichiometry.
- The limiting reactant is the one that is consumed first and sets a limit on the quantity of product(s) that can be produced, and the one which remains unconsumed after the final reaction is in Excess.
- Calculate the moles of each reactant present and contrast it with the mole ratio of the reactants in the balanced equation to determine which reactant is the limiting one.
Here,taking the stoichiometry into consideration, we find that the reaction happens with 1:1 ratio; so, adding twice the amount of Na₂CO₃ will lead to its excess making the other the limiting reactant, hence, it would not affect the yield of the product.

Answer:
No, he is not.
Explanation:
When he let the rubber band go, the band compresses, so there's elastic potential energy in it, which will be transformed into kinetic energy when it gains velocity and flies across the room.
Then, Elias had inverted the concepts: the experiment demonstrates the transformation of elastic potential energy to kinetic energy.
