Answer:
a) 2CH4(g) + S8(s) → 2CS2(l) + 4H2S(g)
b) <u>4.24 moles CS2</u>
<u>c) 8.48 moles H2S</u>
Explanation:
Step 1: The unbalanced equation
CH4(g) + S8(s) → CS2(l) + H2S(g)
(a) Balance the equation. (Use the lowest possible coefficients. Include states-of-matter under the given conditions in your answe.)
2CH4(g) + S8(s) → 2CS2(l) + 4H2S(g)
(b) Calculate the moles CS2 produced when 2.12 mol S8 is used.
For 2 moles CH4 we need 1 mol S8 to produce 2 moles CS2 and 4 moles H2S
For 2.12 moles S8 we'll have 2*2.12 = <u>4.24 moles CS2</u>
(c) How many moles H2S are produced?
For 2 moles CH4 we need 1 mol S8 to produce 2 moles CS2 and 4 moles H2S
For 2.12 moles S8 we'll have 4*2.12 = <u>8.48 moles H2S</u>
98 °C + 273.15 = 371.15 K
