Tantalum (Ta), Osmium (Os) and Rhodium (Rh) are metals.

<u>Explanation</u>:

Metals are good conductors of heat and electricity and they can be hammered into sheets (malleable).Mainly most of them are solids. Ta, Os and Rh are all metals with a same platinum group.
Tantalum (Ta) with a atomic number 73 is a lustrous transition metal which is highly corrosive resistant. It is mainly used in making electronic equipment.
Rhodium (Rh) is a chemical element with atomic number 45 is a rare, silvery white,hard and corrosive resistant metal. Osmium (Os) with a atomic number 76 is a hard, brittle bluish-white transition metal.

Pachacha [2.7K]

Water boils when its vapor pressure equals the prevailing atmospheric pressure over the water. In order for water to boil at 50 ºC, the pressure over the water would need to be reduced to a point greater equal to the vapor pressure of the water (92.5 torr).

A mixture is made by combining 1.49 lb of salt and 3.82 lb of water.

Pavel [41]

Answer:

28%

Explanation:

concentration=(solute mass/solution mass)*100

C=concentration

md-solute mass

ms-solution mass

the solution mass is equal to the sum of the solute and solvent mass

ms=3.82+1.49=5.31lb

c=1.49/5.31 * 100=0.28*100=28%

Identify the neutralization reaction.

dusya [7]

The neutralization reaction among all the reactions would be the one between an acid and a base to produce salt and water.

<h3>What is a neutralization reaction?</h3>

It is a reaction involving an acid and a base to produce salt and water.

From the list of reactions, the only reaction that involves acid and a base with salt and water being the products is the first reaction.

Thus, the neutralization reaction is represented by the equation:

$2H_3PO_4 + 3Ba(OH)_2 --- > 6H_2O + Ba(PO_4)_2$
