What is a property of most metals?

1 answer:

5 0

(2) They tend to lose electrons easily when bonding is the correct answer.

All metals have either one, two, or three valence electrons. Therefore, they tend to lose these valence electrons in order to have eight valence electrons like noble gases do.

Hope this helps~

When hydrogen sulfide gas is bubbled into a solution of sodium hydroxide, the reaction forms sodium sulfide and water. How many

My name is Ann [436]

Answer:

0.0803g of Na2S are produced

Explanation:

Hydrogen sulfide, H2S, reacts with sodium hydroxide, NaOH, to produce sodium sulfide, Na2S and water.

2NaOH + H2S → 2H2O + Na2S

To solve this question we must find the moles of each reactant. With the chemical quation we can find the limiting reactant. With limiting reactant we can find the moles of Na2S and its mass

<em>Moles NaOH -Molar mass: 40g/mol-</em>

0.0823g * (1mol / 40g) = 0.002058moles

<em>Moles H2S -Molar mass: 34.082g/mol-</em>

2.68g * (1mol / 34.082g) = 0.0786 moles

For a complete reaction of 0.0786 moles of H2S are needed:

0.0786 moles H2S * (2mol NaOH / 1mol H2S) = 0.157 moles NaOH

As there are just 0.002058 moles, <em>NaOH is limiting reactant.</em>

The moles of Na2S produced are:

0.002058moles NaOH * (1mol Na2S / 2mol NaOH) = 0.001029 moles Na2S

<em>Mass Na2S -Molar mass: 78.0452g/mol-</em>

0.001029 moles Na2S * (78.0452g / mol) =

<h3>0.0803g of Na2S are produced</h3>
