Methane, the chief component of natural gas, burns in oxygen according to the equation CH4(g) + 2 O2(g) > CO2(g) + 2 H2O(g)
If 7.0 mol of CH4 react with an unlimited amount of oxygen, what amount (in moles) of H2O(g) will be produced?

Step-by-step explanation:

From the equation, we see that 1 mol of methane produces 2 moles of water. To find the amount of water produced if 7.0 moles of methane react, we use the following proportion:

1 mol of methane / 7 moles of methane   = 2 moles of water / x moles of water

x = 7*2 = 14 moles of water

(- 1, 0 )

step-by-step explanation:

an x- intercept is where the function crosses the x- axis.

to find the x- intercept/s look for the value of x when f(x) = 0

from the given table there are 3 values of x where f(x) = 0

when x = - 1, x = 2, x = 3

the one that is listed is (- 1, 0 )

step-by-step explanation:

a triangle's   full angle is 180 degrees so 180 - 156 = 24. 24/2=12
