Answer:

14.2 L H2S

Explanation:

Mole ratio

2 mol H2S:2 mol SO2

We are just looking for volume, so the required amount is the same as the produced amount as long as the mole ratio is balanced.

klemol [59]

Answer:

The concentration of dilute solution is 0.72M

Explanation:

According to the given question

V1=30 ml

S1 = 12 M

V2= 500 ml

then S2 =?

we all know that V1S1=V2S2

or S2= V1S1÷V2

or S2 = 30×12÷500

or S2= 360÷500

or S2 =0.72 M.

The concentration of dilute solution is 0.72 M

What does heat and pressure have to do with<br> the rock cycle?

UkoKoshka [18]

Answer

Metamorphic rocks form from heat and pressure changing the original or parent rock into a completely new rock. The parent rock can be either sedimentary, igneous, or even another metamorphic rock. The word "metamorphic" comes from Greek and means "To Change Form". ... This changing of rock types is called the "Rock Cycle".

3.84 Kg of sodium chloride is needed to lower the freezing point of the water so that ice melts.

Explanation:

Data given:

mass of ice = 30 Kg

molar mass of NaCl = 58.5 grams/mole

ΔT(depression in freezing point) = 15.4 F or - 9.22 degrees

Kf = 1.86 degree C/ mole

Molality = ?

mass of NaCl =?

i = 2 (because NaCl breaks into 2 ions)

ΔT = iKfm equation 1

Depression in freezing point when ice melts, the temperature is 0 degrees so

the depression in temperature = 9.22 degrees

putting the values in the equation:

9.22 = 2 x 1.86 x $\frac{mass}{58.5}$ x $\frac{1}{30}$

mass = 3.84 kg of NaCl will be required to lower the freezing point of the water so that the ice melts.
