Answer:
The answer is
<h2>0.784 g/mL</h2>
Explanation:
The density of a substance can be found by using the formula
<h3>
</h3>
From the question
mass of liquid = 9.8 g
volume = 12.5 mL
The density is
We have the final answer as
<h3>0.784 g/mL</h3>
Hope this helps you
Answer:
C. 63.3%
Explanation:
Theoretical yield = 47.2g
Actual yield = 29.9g
Percentage yield = ?
The percentage yield of a compound after chemical synthesis is the ratio of the actual yield to the theoretical yield multiplied by 100.
Percentage yield = (actual yield / theoretical yield) × 100
Percentage yield = (29.9 / 47.2) × 100
Percentage yield = 0.6334 × 100
Percentage yield = 63.34%
The percentage yield of Fe is 63.34%
Answer: What best describes the reaction is "A single replacement reaction takes place because zinc is more reactive than hydrogen."
I know it's chlorine because it have 17 dots which means it has 17 protons but I don't know the reactivity
