Answer:

The volume will be 2600 L.

Explanation:

Initial temperature ( $T_{1}$ ) = 25°C = (25 + 273) K = 298K

Final temperature ( $T_{2}$ ) = 54°C = (54 + 273) K = 327 K

By using the combined gas law equation,

$\frac{P_{1} V_{1} }{T_{1} }$ = $\frac{P_{2} V_{2} }{T_{2} }$

or, $\frac{760* 1200}{298}$ = $\frac{380* V_{2} }{327}$

or, 3060 × 327 = 380 × $V_{2}$

or, $V_{2}$ ≈ 2600 L

Hence the volume of the balloon will be about 2600 L.

Answer:

a) H2S:SO2 = 2:2 and O2:H2O = 3:2

Explanation:

2H2S + 3O2 → 2SO2 + 2H2O

⇒ H2S:SO2 = 2 mol H2S / 2 mol SO2 ≡ 2 : 2

⇒ O2:H2O = 3 mol O2 / 2 mol H2O ≡ 3 : 2

daniel has a sample of pure copper. its mass is 89.6 grams (g), and its volume is 10 cubic centimeters (cm3). what’s the density

77julia77 [94]

D = mass / volume

d = 89.6 / 10

d = 8.96 g/cm³
