The table compares the masses of three unknown subatomic particles.
relative mass of particles
particle relative mass
p 1
q 0.00054
r 0.99
which particle is most likely present in the nucleus of the atom?

P and R

Explanation:

The nucleus contains almost the entire mass of the atom.

I would expect both P and R to be in the nucleus.

P and R

Explanation:

An atom is smallest unit of a matter or substance. It consists of three subatomic particles : electrons, protons, neutrons.

Protons and neutrons are located in the center of an atom where most of the mass of an atom is concentrated.

Electrons are located outside the nucleus where they orbit in different energy levels around the nucleus and weigh much less than protons and neutrons.

As particles P and R have relative masses of 1 and 0.99 , which are comparable and thus contribute most to the mass and are located in the nucleus.

Thus particle P and R are most likely present in the nucleus of the atom.

when the volume of gas is   changed from   717.73 ml   to 852 ml   the temperature will   change   from 315   c to 452   c

    calculation

this is calculated using the charles law formula

that is,   v1/t1 = v2/t2

          v1=?

        t1 = 315 c   into   kelvin = 315 +273 = 588 k

        v2 = 852   ml

        t2 = 425c + 273 =698 k

make v1   the subject of the formula ( by   multiplying both side by t1)

  v1=( v2 xt1) / t2

v1= (852 ml   x 588 k)/ 698 k= 717.73 ml

i wish i could but this one is weird give me abc and i can solve it.
