is this an algebra class? if so it just
11.50x + 16y = 20.25
This is a geometric series with first term e^3 and common ratio e^-2. The sum of it will be
.. e^3/(1 -e^-2) ≈ 23.229277815766...
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
Brigitte is shorter than 5 feet. (Brigitte's height=h)
We write this in inequality form
Brigitte's height is h
So 'h' is shorter than 5 feet
Shorter means less than so we use < symbol. We should not use = symbol because height is shorter than 5 not equal to 5.
Suppose if it is given ' height is more than 5 feet ' then we use greater than symbol (>)
h is less than 5 feet
h < 5
Inequality is h < 5
