<span>These gas molecules are much smaller than the distance between them.
</span><span>So, most of the volume of a gas is therefore empty space.
</span><span>There is no force of attraction between gas particles or between the particles and the walls of the container.
Because there is a large amount of empty space between gas molecules,the gas has property of low density.</span>

slava [35]

Answer:

105 grams PbI₂

Explanation:

Pb(NO₃)₂ + 2KI => 2KNO₃ + PbI₂(s)

moles Pb(NO₃)₂ = 0.265L(1.2M) = 0.318 mole

moles KI = 0.293(1.55M) = 0.454 mole => Limiting Reactant

moles PbI₂ from mole KI in excess Pb(NO₃)₂ = 1/2(0.454 mole) = 0.227 mol PbI₂

grams PbI₂ = 0.227 mol PbI₂ x 461 g/mole = 104.68 g ≈ 105 g PbI₂(s)

A quantity of 85.0 mL of 0.900 M HCl is mixed with 85.0 mL of 0.900 M KOH in a constant-pressure calorimeter that has a heat cap
san4es73 [151]

Answer:

There is a 1:1 neutralization reaction,  so, number of moles:

0.085 l * 0.900 mol/ L = 0.0765 mol HCL

The heat produced:  0.0765 mol * -56.2 kJ/mol = -4.229 kJ (this is the heat of neutralization)

Change in temperature:    The mass to use in the equation Q=cmT.  

4229 J / (4.186 J/gC*170 g) = 6.042 C

Add to the initial temperature:

18.24 + 6.042 = 24.29 C°

inysia [295]

Answer: has zero mass

is an electron

has a -1 charge

is electromagnetic energy

Explanation:

A beta-particle is an electron emitted from the nucleus of an atom following the decay of a neutron into a proton. Beta rays are deflected by a magnetic field in a direction that indicates a negative charge, thus they are electromagnetic in nature.

The beta particle released is basically a electron with -1 charge and no mass.

General representation of beta particle in the form of _Z^A\textrm {X} given as _{-1}^0e

where,

Z represents Atomic number

A represents Mass number

X represents the symbol of an element
