denser than water
burns readily in air
boiling point of –1.1°C
odorless
does not react with water
burns readily in air
does not react with water
<h3><u>
Explanation:</u></h3>
The type of alkane that is used in many products includes Butane. It is found as a natural gas in the environment. It is found on the deeper part of ground. It can be obtained by drilling process and gets used up in many of the products that is used for commercial purposes.
Molecular mass that is associated with butane is 58.12 g/mol. The boiling point of butane is -1 degree Celsius and -140 degree Celsius is its melting point. It is a liquefied gas and does not react with water. It will burn in air more readily.
The mass of gas A is 11.56. i got this answer by 0.68 multiplied by 17. because in this problem the key word is times.
Answer:
lower,emitted
Explanation:
when electron changes level, it decreases energy and emits photon.
photon is emitted when it goes from higher to lower energy level
