Answer:

B. They bond identical atoms together

Explanation:

Metallic Bond:  This is the bond that exists among the atoms of the metal.  This is a type of electrostatic attraction between conduction electrons of metallic atom and their positively charged metal ions.

                                        <em>(figure attached)</em>

Example:  

Copper is a metallic element and its atoms consist of metallic bond among their selves.  

Options A, B, D are not correct as all states for a kind of ionic bond formation.

Ionic bond:  

It form by the complete transfer of electron from one atom to other

It is formed among two atoms of different electronegativities.

Also metals are electro-positive and non -metals are electro-negative so they form ionic bond.

Example is NaCl where sodium is a metal and Chloride is non-metal and they from ionic bond.

What is the percent by mass in a solution with 10.0 grams of solute and 25.0 grams of solvent?
rewona [7]

Answer:

Percent by mass of solute is (10/35) x 100 =  28.57%

Percent by mass of solvent is (25/35) x 100 = 71.43%

Explanation:

10.0 grams of solute

25.0 grams of solvent

Total Mass = 35 grams

percent by mass = (Mass A / Total Mass) x 100

Percent by mass of solute is (10/35) x 100 =  28.57%

Percent by mass of solvent is (25/35) x 100 = 71.43%
