Answer:

0.182M Ba(OH)₂

Explanation:

The reaction of barium metal (Ba) with H₂O is:

Ba + 2H₂O → Ba(OH)₂ + H₂

25g of Ba are:

25g Ba × (1mol / 137.327g) = 0.182 moles of Ba. Based in the reaction, 1 mole of Ba produces 1 mole of Ba(OH)₂. That means you will produce <em>0.182 moles of Ba(OH)₂. </em>If the whole volume of your solution is 1.00L, the concentration of barium hydroxide is:

0.182 moles of Ba(OH)₂ / 1.00L = <em>0.182M Ba(OH)₂</em>

weqwewe [10]

Answer:

Within a group trend

Explanation:

The atomic radius of atoms generally increases from top to bottom within a group trend. As the atomic number increases down a group, there is again an increase in the positive nuclear charge.  As the atomic number increases within a period, the atomic radius decreases.
