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
Answer:
35
Step-by-step explanation:
2/5 + 3/7
the least common denominator is 35 because 14/35 + 15/35.
There will have to be 5 because of the 4
I think it's another trick question and the answer is 2000.
Answer:
The sum of the angles that do not measure 22 degrees is equal to 316°
Step-by-step explanation:
The question in English is
A rhombus has a 22-degree angle. How much is the sum of its angles that do not measure 22 degrees worth?
we know that
The opposite internal angles of a rhombus are equal and the adjacent internal angles are supplementary
so
Let
x -----> the measure of an adjacent angle to 22 degrees in the rhombus
x+22°=180°
x=180°-22°=158°
therefore
The sum of the angles that do not measure 22 degrees is equal to
158°+158°=316°
