Click on the element in the periodic table to explore the atomic radii of elements from Period 3 and Group 17. Fill in the missing values in the table so you can compare the atomic radii of the elements. After the table is filled in, compare the values in each column. A = B = C =

1) according to the law of conservation of mass ,in all chemical reactions total mass is unchanged

Answer:             1.0  × 10⁻⁵ msolution:                     as we know ph is given as,                                    ph  = -log [h⁺]and,                                    [h⁺]  =  10^-ph    (1)putting value of ph in eq. 1,                                    [h⁺]  =  10⁻⁵                                    [h⁺]  =  1.0  × 10⁻⁵ m
