Answer:

The volume is 8,22 liters.

Explanation:

The unit of pressure (from Torr to atm) must be converted: 760 Torr = 1 atm

760 Torr---1 atm

23,44Torr--x= (23,44Torr x 1 atm)/760 Torr= 0,0308 atm

PV=nRT V= (nRT)/P

V=(0,00554 mol x 0,082 l atm/K mol x 557 K)/ 0,0308 atm

V=8, 22 L

Which layer of Earth has partially melted material that moves the tectonic plates?
beks73 [17]

The layer of Earth that has partially melted material that moves the tectonic plates is Mantle.  The correct option is C.

<h3>What are the layers of the Earth?</h3>

The Earth is divided into three layers: the crust, the mantle, and the core. This is the earth's outer layer, and it is composed primarily of solid rock, primarily basalt and granite. Oceanic crust and continental crust are the two types of crust.

The layer of Earth that has partially melted material that moves the tectonic plates is Mantle.

Thus, the correct option is C.

PLEASE PLEASE HELP ME!!!A 450 ml gas sample has a pressure of 1.25 atm at 65 °C. What is the temperature, in °C, at which the ga
Arlecino [84]

Answer:

89°C

Explanation:

Combined Gas Law (P₁V₁)/T₁ = (P₂V₂)/T₂

(1.25 atm)(450 mL)/(65°C) = (0.89 atm)(865 mL)/T₂

8.653846154 = 769.85/T₂

T₂ = 769.85/8.653846154

T₂ = 88.96044444 = 89°C

The volume of a gas that occupies 9 L at a temperature of 325K is 12.46L.

<h3>How to calculate volume?</h3>

The volume of a given gas can be calculated using the following Charle's law equation:

V1/T1 = V2/T2

Where;

  • T1 = initial temperature
  • T2 = final temperature
  • V1 = initial volume
  • V2 = final volume

  • V1 = 9L
  • V2 = ?
  • T1 = 325K
  • T2 = 450K

9/325 = V2/450

325V2 = 4050

V2 = 4050/325

V2 = 12.46L

Therefore, the volume of a gas that occupies 9 L at a temperature of 325K is 12.46L.
