Asolution of hno3 is standardized by reaction with pure sodium carbonate. 2h++na2co3⟶2na++h2o+co2 a volume of 26.80±0.05 ml of hno3 solution was required for complete reaction with 0.9369±0.0009 g of na2co3 , (fm 105.988±0.001 g/mol ). find the molarity of the hno3 solution and its absolute uncertainty g

answer: the rate of diffusion increases with increase in temperature.

increase in temperature, increases the molecular/particles speed (kinetic energy. diffusion means movement of particles through the material.

generally, the heavier the particle the more it interacts with the environment and more the temperature matters. so higher temperature results in higher diffusion.

there is none because earth is stationary and flat.

answer: atomic mass was originally used to arrange elements on the periodic table, but is no longer used to organize the modern version.

explanation:

originally atomic mass was used to arrange elements on the periodic table from left to right in a row. each column then shows similar properties of elements of a group.

in modern periodic table, the atoms are arranged in increasing atomic number. as atomic number represents the number of protons in an atom which is unique for every atom.
