Rubidium or strontium have larger a larger atomic radius since the further left on the periodic table you go, the larger the sizes of the atoms are.  This trend can be explained through effective nuclear charge which explains how the further left and down you go, the less the atoms nucleus is able to pull in the electrons around it.<span />

vitfil [10]

Answer:

Mass = 23.36 g

Explanation:

Given data:

Number of particles of CO₂ = 3.20 ×10²³

Mass of  CO₂ = ?

Solution:

1 mole contain 6.022×`10²³ particles,

3.20 ×10²³ particles  × 1 mol / 6.022×`10²³ particles

0.531 mol

Mass of CO₂:

Mass = number of moles × molar mass

Molar mass = 44 g/mol

Mass =  0.531 mol× 44 g/mol

Mass = 23.36 g

Which is a characteristic of weak acids and weak bases?
Lera25 [3.4K]
Ka and Kb values of weak acids and weak bases are small.

This is because weak acids and weak bases do not dissociate completely, favoring the reactants more than dissociating into the product of H+ or OH-.
