Answer:
A & B
Step-by-step explanation:
Answer: Easy, graph and solution
Step-by-step explanation: First what you want to do use the slope intercept form to find the slope and y intercept; -1/2 and y intercept (0,4). Any line can be graphed using 2 points. Select two x values, plug them into the equation to find the corresponding y values. Solution
1.) Step; x and y
Table:
0║4
8║0
- All you had to do is divide 0=-x/2 +4= . (8) For the x intercept you get 8and for y you get 4 because you divided 0=-0/2+4
Answer:
Step-by-step explanation:
Identify the slope, m. calculate slope between two known points of the line using the slope formula.
Find the y-intercept. substituting the slope and the coordinates of a point (x, y) on the line in the slope-intercept formula and then solve for b.
Answer:
2H2S (g) + 3O2 (g) → 2H2O (l) + 2SO2 (g)
Calculate ΔH° from the given data. Is the reaction exothermic or endothermic?
ΔH°f (H2S) = -20.15 kJ/mol; ΔH°f (O2) = 0 kJ/, mol; ΔH°f (H2O) = -285.8 kJ/mol; ΔH°f (SO2) = -296.4 kJ/mol
