<span>13.2 gallons=49.9 liters
the gas is the octan C8H18
the combustion of Octan equation is
C8H18 + 25/2 O2-------------------> 8CO2 + 9 H2O
1mole 8 moles
n(C8H18)=a n(CO2)=b
so
1 mole/a = 8moles /b
and b= 8molesx a
we must find the value of a, molar volume of a gas is v= 22.4l/mol=V/a, so a=V/v= 49.9/22.4= 2.23 moles
and b=8 x a=8x 2.23=17.85 moles
M(CO2)=m(CO2)/n(CO2)====> m=n x M=17.85 * (12+2x16)= 785.4 g
m(CO2)=785.4g = 1.57 pound</span>
Answer:
t+b<=122
Step-by-step explanation:
You know that the total is a maximum of 122, and it can be either tacos or burritos, so it is that.
Answer:
16
Step-by-step explanation:
count the dots. each is one observation
Answer:
c. mean: 9/20, median: 2/5, mode: 3/4
Step-by-step explanation:
3/4
,
2/5
,
1/10
,
3/4
,
1/4
It is best to order this list from low to high
low end, 1/10, 1/4, 2/5, 3/4, 3/4
middle is 2/5
mode = 3/4 the most repeated
mean: [2/20 + 5/20 + 8/20 + 15/20 + 15/20] * (1/5)= 45/20 *(1/5)
Answer:
The rate of change for the interval shown in the table is 1 , so the function is a linear function.
Step-by-step explanation:
See the table attached.
The table shows selected points from a function.
Now, the given interval is x = 1 to x = 4.
For, x = 1, f(x) = 2 and for x = 4. the function f(x) = 5.
Therefore, the rate of change for the interval shown in the table i.e slope of the line is 
and it is constant throughout the interval so the function is a linear function. (Answer)
