Answer: the correct answer is B. Hallogens hope this helped mind helping out with making me brainliest?
Skeleton equation is actually a chemical reaction whee the reactants and products are written in their chemical formula. In this problem, this is actually a combustion reaction of butane. The chemical formula for butane is C₄H₁₀.
<em>C₄H₁₀ (l) + 6.5 O₂ (g) --> 4 CO₂ (g) + 5 H₂O (l)</em>
Answer:
Accuracy decreases
Explanation:
All meaurements have an uncertainty (That is, the error of the measurement). The uncertainty of graduated cylinders is higher than uncertainty of pipets.
The accuracy is how close is the measurement to the real value.
If you use graduated cylinders rather than pipets, <em>accuracy decreases </em>because you will have more uncertainty in the measurements putting of the real value and the real value.
Answer:
Explanation:
The part of 10 O2 is wrong.
Explanation:
The correct equation can be written as follows:
2 C 4 H 10 + 13 O 2 → 8 C O 2 + 10 H 2 O
The equation was not balanced before.
For a balanced chemical reaction, the number of atoms before and after the reaction should be the same. This is because matter is neither created not destroyed in a reaction, It changes from one form to another through chemical reactions.
