- How does electronegativity determine that the type of bond between . . .
According to the Pauling scale, the electronegativity of chlorine (Cl) is 3 16 and the electronegativity of sodium (Na) is 0 93 The electronegativy difference, Delta"EN", is 2 23, which means that the chemical bond between sodium and chlorine is ionic, forming the ionic compound sodium chloride (NaCl) If you would like a printable periodic table that includes the Pauling electronegativities
- Equal quantities of sodium hydroxide, and hydrochloric acid . . . - Socratic
Equal quantities of sodium hydroxide, and hydrochloric acid are mixed What is the colour of the solution if universal indicator is added? ChemistryChemical ReactionsChemical Reactions and Equations
- What is the molar mass of sodium carbonate, (Na2CO3)? - Socratic
The molar mass of sodium carbonate is "105 987 g mol" To calculate the molar mass of a compound, multiply the subscript of each element from the formula times the molar mass of the element
- Question #34c34 - Socratic
Sodium is more metallic than aluminium If you note their locations on the periodic table you will see that sodium is in the group called alkali metals If you look at the location of aluminium you will note that it is right next to the metalloids which are elements that share characteristics of metals and nonmetals In general, the further the metal is to the left on the periodic table, and
- Question #63908 + Example - Socratic
Your solution contains 0 32 g of sodium chloride A percent concentration by mass expresses the ratio between the mass of the solute, in your case sodium chloride, and the total mass of the solution, multiplied by 100 "%mass" = "mass of solute" "mass of solution" * 100 So, you know that your sample weighs 16 g and that it's 2% m m sodium chloride You can use this data to determine how many
- What would be different in your observations between Na and K?
Sodium will be fairly inert in 25% IPA in toluene, and react quite sluggishly On the other hand, sodium metal will react fairly vigorously with ethanol, whereas potassium will give a few flames, and a violent reaction
- Question #c92ff - Socratic
Here's what I got Molality is defined as the number of moles of solute present for every "1 kg" of solvent You know that your solution has a molarity of "3 M", which implies that every "1 L" of solution contains 3 moles of sodium chloride, the solute To make the calculations easier, let's pick a "1-L" sample of this solution Use the molar mass of sodium chloride to calculate how many grams
- Question #851e9 + Example - Socratic
This process creates a salt called sodium chloride, or table salt itself! As always, water will be produced from the reaction I hope this helps!
