What is the meant by atomic radius
krek1111 [17]

Atomic radius defines the size of an atom.  

Explanation:

Atomic radius is defined as “one-half the distance between the nuclei of two identical atoms that are bonded together.” If ‘r’ is the atomic radius and ‘d’ the distance in between nuclei of two atoms that are identical and bonded, then r = d/2.

The units used to express atomic radius are picometer, nanometer, and Angstroms.

In the periodic table, the atomic radius of elements decreases with elements across a <em>period</em> (left-right) and increases with elements down a group.

Typically, the hydrogen gas is bubbled through water for col- lection and becomes saturated with water vapor. Suppose 240. mL of
klio [65]

Answer:PH2=0.994atm, mass of zinc=0.606g

Explanation:

Equation for the reaction is written as;

Zn(s) + 2HCl(aq) - ZnCl2(aq) + H2(g)

V= 240ml = 0.240L

T= 30.8oC = 303.8K

Ptotal= 1.036atm

Pwater = 32mmHg at 30oC = 0.042atm

Therefore

PH2 = Ptotal - Pwater

= 1.036-0.042atm

=0.994atm

But PV= nRT

n = PV/RT

= 0.994x0.240/0.0821x303.8

= 0.24/24.94

=0.009324moles

For the grams of zinc

n=mass in grams/molar mass

Mass in grams = no of moles x molar mass

=0.009324x65 = 0.606g
