The picture shows two containers filled with a gas, both initially at room temperature. B
Ice
Heat
Which statement is correct? (5 points)
О а
The gas particles in both containers have the same average kinetic energy because they have equal number of particles.
Ob
The gas particles in both containers have the same average kinetic energy because they have the same volume.
Ос
The average kinetic energy of the gas particles is greater in container A because it has a lower temperature.
The average kinetic energy of the gas particles is greater in container B because its particles move faster.
Od

it is to be noted that an alpha particle is an helium nucleus. so it contains 2 protons 2 neutrons and has a mass number of 4. when alpha decay particles are ejected from the nucleus it gets transformed into an atom which has atomic number less than 2 and a mass number less than 4.

an equation that could represent alpha decay is radium 226 decay of alpha particle forms radon 222.

"among the transition metal elements, manganese and zinc have a slight lowering of electronegativities. the reason behind this is that the nuclear charges of these elements are slightly weaker than the other transition metal elements due to the way their valence electrons are filled up. both manganese and zinc have their valence electrons filled up to the 4th shell with 1 pair of electrons (4s2) completely occupying it. although the electrons in the 3rd shell (3d) are yet to be paired since the outer most shell is filled up, the ability of the nucleus to attract electrons is lessened. hence,   the electronegativity (or the ability to attract electrons) is lessened."

i believe it is c.) 1575 j.
