Methane, CH4 burns in oxygen gas to form water and carbon dioxide
Triss [41]

Answer:

2 CH4(g) + 4 O2(g) --> 2 CO2 (g)+ 4 H2O(g)

Step-by-step explanation:

The number are subscripts.  

Now count the number of each kind of atom on the left and right side of the equation. Note, you have 4 H on the left and as written you have only 2 on the right. So add a coefficient-- a number in front of the formula.  

CH4 +O2 ----- CO2 + 2 H2O  

With the added coefficient in front of water, the number of hydrogens balance but the number of oxygens do not. There are only 2 oxygens on the left and a total of 4 oxygens on the right. A coefficient of 2 in front of oxygen on the left balances the equation.

Find the slope of the line (4,2) and has an x-intercept of 7
Sergio [31]
If the x-intercept is 7, then the coordinate is 7 along the x-axis and 0 up the y-axis, so the coordinate is (7,0). We now have the two points (4,2) and (7,0).
You can find out the slope of any line using the general equation:
\frac{y_{2}-y_{1}}{x_{2}-x_{1}}
(0-2)/(7-4) = -2/3
The slope of the line is -2/3x.

Find the discriminant of 3x^2-10x=-2
Oksanka [162]

Answer:

76

Step-by-step explanation:

given a quadratic equation in standard form : ax² + bx + c = 0 : a ≠ 0

then the discriminant is Δ = b² - 4ac

given 3x² - 10x = - 2 ( add 2 to both sides )

3x² - 10x + 2 = 0 ← in standard form

with a = 3, b = - 10 and c = 2

b² - 4ac = (- 10)² - (4 × 3 × 2) = 100 - 24 = 76
