The gas tank of a 2015 Nissan Sentra holds 13.2 gallons. How many pounds of carbon dioxide are produced by burning an entire tan
OLEGan [10]
<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>

What are the features of the quadratic function ƒ(x) = x2 + 10x + 21?
belka [17]

Answer:

B is the answer

Step-by-step explanation:

The intercept is at x = 0 then y = 21 or (0,21) so A and D drop out.

The vertex (-5, -4) satisfies the equation but (-4,-5) does not so C drops out leaving B.
