<h3>Subatomic structure:--</h3>
  • A powerful force keeps the subatomic structure of the nucleus together.
  • In addition to holding the nucleons together, which make up the nucleus, it also holds the three quarks together to create a nucleon. A proton or neutron could be a nucleon.
  • Two up quarks and one down quark make up the proton. One up quark and one down quark make form a neutron.
  • There is a weak force as well.
  • The neutron may be converted to a proton and electron combined or a proton may be converted to a neutron mixed with a positron.

<h3>Structure of nucleon:-</h3>
  • A nucleon is a proton or a neutron when seen as a component of an atomic nucleus in chemistry and physics.
  • An isotope's mass number (also known as its nucleon number) is determined by how many nucleons it contains
  • Nucleons were believed to be single, elementary particles up until the 1960s.

<h3>Forces that hold nucleus together:-</h3>
  • The nuclear force, a short-range force between nucleons, is what binds a nucleus together.
  • The nuclear force is repellent at very tiny distances, preventing protons and neutrons from approaching one another too closely.

<h3>How beta emission work?</h3>
  • The beta emission process converts a neutron into a proton, an electron, and an antineutrino. A work force is involved in beta decay.

The vapor pressure of water at 25.0°C is 23.8 torr. Determine the mass of glucose (molar mass = 180 g/mol) needed to add to 500.
mrs_skeptik [129]

According to Raoult's law the relative lowering of vapour pressure of a solution made by dissolving non volatile solute is equal to the mole fraction of the non volatile solute dissolved.

the relative lowering of vapour pressure is the ratio of lowering of vapour pressure and vapour pressure of pure solvent

\frac{p^{0-}p}{p^{0}}=x_{B}

Where

xB = mole fraction of solute=?

p^{0}=23.8torr

p = 22.8 torr

x_{B}=\frac{23.8-22.8}{23.8}=0.042

mole fraction is ratio of moles of solute and total moles of solute and solvent

moles of solvent = mass / molar mass = 500 /18 = 27.78 moles

putting the values

molefraction=\frac{molessolute}{molesolute+molessolvent}

0.042=\frac{molessolute}{27.78+molessolute}

1.167+0.042(molesolute)=molessolute

molessolute=1.218

mass of glucose = moles X molar mass = 1.218 X 180 = 219.24 grams

10. At 573K, NO2(g) decomposes forming NO and O2. The decomposition reaction is second order in NO2 with a rate constant of 1.1
leva [86]

Answer:

48.67 seconds

Explanation:

From;

1/[A] = kt + 1/[A]o

[A] = concentration at time t

t= time taken

k= rate constant

[A]o = initial concentration

Since [A] =[A]o - 0.75[A]o

[A] = 0.056 M - 0.042 M

[A] = 0.014 M

1/0.014 = (1.1t) + 1/0.056

71.4 - 17.86 = 1.1t

53.54 = 1.1t

t= 53.54/1.1

t= 48.67 seconds

Hence,it takes 48.67 seconds to decompose.
