Gas at room temperature
Usually do not react with other elements
Are in a group called noble gasses
Are non metals
2C6H14 + 13O2 ---> 6CO2 +14H2O
M(C6H14)=12.011*6 +1.008*14 ≈ 86.17 g/mol
86.17 g C6H14 is 1 mole.
2C6H14 + 13O2 ---> 6CO2 +14H2O
from reaction 2 mol 6 mol
from the problem 1 mol 3 mol
M(CO2)= 12.011 + 2*15.999= 44.009 g/mol
3 mol CO2*44.009 g/1 mol CO2 ≈ 132.0 g CO2
Answer : 132.0 g CO2
It's very simple.
Energy =
where, h= Planck's constant = 6.6 x
c= speed of light = 3 x
m/s
= wavelength
So, energy =
= 1.65 x
J
=1.65 x
KJ

definition
chemical A chemical property is a characteristic of a particular substance that can be observed in a chemical reaction. Some major chemical properties include flammability, toxicity, heat of combustion
examples flammability, toxicity, acidity, reactivity
pretty much the difference is is that chemical changes its chemical reaction involving the rearrangement of the atoms of one or more substances and a change in their chemical properties or composition, resulting in the formation of at least one new substance Physical change does not do that
Answer:
Trail Mix
Explanation:
The best description for the snack that Ben is eating would be Trail Mix. This is a very common snack for hikers, hence the name, since it is very healthy and great for taking on hikes since it does not get affected by the sun. This snack was originally called GORP which stands for "good old raisins and peanuts" because the snack originally contained only raisins and peanuts. It has since changed to include various different ingredients such as a variety of nuts, chocolate pieces, dried fruit, cereal etc.
