# What amount in moles does 242 L of carbon dioxide occupy at 1.32 atm and 20 degrees C

13.28 mol.

Explanation:

• We can use the general law of ideal gas: PV = nRT.

where, P is the pressure of the gas in atm (P = 1.32 atm).

V is the volume of the gas in L (V = 242.0 L).

n is the no. of moles of the gas in mol (n = ??? mol).

is the general gas constant (R = 0.0821 L.atm/mol.K).

T is the temperature of the gas in K (T = 20.0° + 273 = 293.0 K).

n = PV/RT = (1.32 atm)(242.0 L)/(0.0821 L.atm/mol.K)(293.0 K) = 13.28 mol.

The time it takes for a planet to make a complete rotation is also which of the following? A.
the length of its day

B.
the length of its year

C.
the length of its month

D.

An action or the movement of the planet on its tilted axis that involves a whole turn or circular motion from its initial point and back to it is called a rotation.

The time it takes for a planet to make a complete rotation is the length of its day.

### What is rotation?

Rotation of the planet is the circular turn or the motion of the planets on its axis from one point and back to it.

The rate of the rotation of the different planets varies based on their sizes and distances from the sun. It is also called the length of the day as the rotation defines the circular motion it completes in a defined day.

Therefore, option A is correct.

1 and column 2?
1
sugar
ice
diamond
S
AS
rubber
wax
plastic
column 1 Atoms
column 2. lons
column 1 Crystalline
column 2 Noncrystalline
column 1. Definite shape
column 2. Definite volume
column 1 Viscous
column 2 Nonviscous

column 1: they are solids that form crystals.

column 2: Are liquid solutions.

Explanation:

Crystals are solids, some of them can have viscosity like glass.

Liquid solutions, are formed by some ions dissolved in water, so they can have a definite volume and could be a liquid that is nonviscous because they are dissolved in water.

Explanation:

How much heat is required to melt 26.0 g of ice at its melting point?

Heat required to melt 26.0 g of ice at its melting point is 8.66 kJ.

Explanation:

Number of moles of water in 26 g of water: 26× moles

=1.44 moles

The enthalpy change for melting ice is called the entlaphy of fusion. Its value is 6.02 kj/mol.

we have relation as:

q = n × ΔH

where:

q  = heat

n  = moles

ΔH  = enthalpy

So calculating we get,

q= 1.44*6.02 kJ

q= 8.66 kJ

We require 8.66 kJ of energy to melt 26g of ice.

Which particles make up the nucleus of an atom? A. protons and electrons B. neutrons and electrons C. protons only D. protons and neutrons E. neutrons only

The correct answer is option D, that is, protons and neutrons.

The center of an atom is known as the nucleus, it comprises nucleons, that is, neutrons and protons, and is enveloped by the cloud of electrons. The nucleus exhibits the majority of the mass of the atom in spite of being a very small constituent of the atom. Approximately all the atom's mass is formed of the neutrons and protons in the nucleus with a very small donation from the orbiting electrons.

Which of the following is not a part of Earth’s system? a. hydrosphere b. geosphere c. biosphere d. chronosphere

Answer : The correct option is (d).

Explanation:

Hydrosphere : It is portion or surface covered by water or fluid on the Earth. Such as : oceans, lakes , lakes, clouds etc.

Geosphere: It is a solid portion of the Earth system which includes substance found on interior side of the Earth like: rocks,minerals landforms etc. Basically it provides shape to outermost layer of the earth.

Biosphere: Regions of surface, atmosphere and hydrosphere of the Earth occupied by living organisms is known as biosphere.

Chronospere: It is mass teleportation device which can move object through space and time.

So, from all the above options chronosphere is not a part of the earth system. Hence correct option is (d).

it is D.chronoshpere
