A gas balloon has a volume of 106.0 liters when the temperature is 45.0 °C and the pressure is 740.0 mm of mercury. What will it
Zarrin [17]

Answer:

New volume V2 = 92.7 Liter (Approx)

Explanation:

Given:

V1 = 106 l

T1 = 45 + 273.15 = 318.15 K

P1 = 740 mm

T2 = 20 + 273.15 = 293.15 K

P2 = 780 mm

Find:

New volume V2

Computation:

P1V1 / T1 = P2V2 / T2

(740)(106) / (318.15) = (780)(V2) / (293.15)

New volume V2 = 92.7 Liter (Approx)

What is the balanced equation of iron (iii) hydrogen carbonate?​
Lynna [10]
<h3>Answer:</h3>

2Fe(HCO₃)₃ → Fe₂(CO₃)₃ + 3H₂O + 3CO₂

<h3>Explanation:</h3>
  • A decomposition reaction is one in which a large compound is broken down into smaller compounds or individual elements.
  • The decomposition reaction Iron (iii) hydrogen carbonate yield iron (iii) carbonate, water and carbon dioxide.

        Fe(HCO₃)₃ → Fe₂(CO₃)₃ + H₂O + CO₂

  • A balanced equation is the one in which the number of atoms of each element are equal on both side of the equation.
  • Therefore; the balanced equation for the decomposition of Iron (iii) hydrogen carbonate is given by;

2Fe(HCO₃)₃ → Fe₂(CO₃)₃ + 3H₂O + 3CO₂

A .60 L sample of nitrogen is heated from 27℃ to 77℃ at a constant pressure. What is the final volume of the gas?
Anon25 [30]

Answer:

CHARLES' LAW

given:

= 600 mL = 0.6 L

= 27 °C = 300.15 L

= 77 °C = 350.15 L

conversion:

= 600 mL (1 L / 1000 mL)

= 0.6 L

= 27 °C + 273.15 K

= 300.15 K

= 77 °C + 273.15 K

= 350.15 K

solution:

= ( × ) ÷

= (0.6 L × 350.15 K) ÷ 300.15 K

= 0.7 L
