Answer: Thus the correct option is D. All of the above describe a mole
Explanation:
According to avogadro's law, 1 mole of every substance weighs equal to molecular mass in grams.
1 mole of every substance contains avogadro's number 
of particles.
Mole is the S.I unit for measuring the amount of substance. It is often used to measure large number of particles.
Thus the correct option is D. All of the above describe a mole
Balance the equation first:
1C4H10 + 13O2 ----> 8CO2 + 10H2O
As we know oxygen is in excess, butane is the limiting reactant.
the ratio between butane and CO2 is 1-8
Therfore
1:8
6:x
x=48
48 moles of CO2 will be produced
<h3><u>Answer;</u></h3>
B) a system is a group of objects analyzed as one unit
C) energy they moves across system boundaries is conserved
<h3><u>Explanation;</u></h3>
- System is a group of objects analyzed as one unit
.
- An open system is a system that freely exchanges energy and matter with its surroundings.
- A closed system is a system that exchanges only energy with its surroundings, not matter. An isolated system does not exchange energy or matter with its surroundings.
