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
515 - 87 = 428
428/245 = 1.746938
To the nearest tenth = 1.7 lbs
Answer:
Height is 8cm
Step-by-step explanation:

Step-by-step explanation:
<u>Step 1: Define</u>
0 = 4x + 4
<u>Step 2: Solve for </u><em><u>x</u></em>
- Subtract 4 on both sides: -4 = 4x
- Divide 4 on both sides: -1 = x
- Rewrite: x = -1
