One chemical property would be reactivity of a particular substance.
Hello!
Answer: 14.3%
Explanation: In order to find the mass percent of hydrogen in this compound, you must determine how many grams of hydrogen you'd get in 100 g of compound.
In your case, you know that an unknown mass of hydrogen reacts with 0.771 g of carbon to form 0.90 g of hydrocarbon, which is a compound that contains only carbon and hydrogen.
Use the total mass of the hydrocarbon to determine how many grams of hydrogen reacted with the carbon.
Now, if 0.90 g of this compound contain 0.129 g of hydrogen, it follows that 100 g of this compound will contain.
So, if 100 g of this compound contain 14.33 g of hydrogen, it follows that the mass percent of hydrogen is 14.3%
Hope this Helps! Have A WONDERFUL Day! :)
Solid liquid gas or plasma. Solid would be ice cubes (frozen state), liquid would be the water inside of the glass, the gas would be when you take that same water and place it on a stovetop to bring to a boiling point. (Gas state) and finally the plasma state is when you your gas particles (from the gas state) if you heat the gas particles, they will turn to plasma.

Answer:
1.61%.
Explanation:
The following data were obtained from the question:
Measured mass = 3.15 g.
Actual mass = 3.10 g
Percentage error =.?
The percentage error of the group can be obtained by using the following equation below:
Percentage error = |Actual mass – Measured mass| / Actual mass × 100
Percentage error = |3.10 – 3.15| /3.10 × 100
Percentage error = 0.05/3.1 × 100
Percentage error = 5/3.1
Percentage error = 1.61%
Therefore, the percentage error of the group is 1.61%.
