What is the molecular mass of Cl 2?
The atomic mass of chlorine is 35.5. A chlorine molecule has two chlorine atoms. Therefore its molecular mass is 71u.
Can atomic and molecular ions be cations or anions?
Yes. Example of atomic cation is Na+. Example of atomic anion is Cl-. Example of molecular cation is NH4+. Example of molecular anion is NO3-.
Is the product of a combination reaction is always a molecular compound?
No, while sometimes it can: 2 H2 + O2 --> 2 H2O (molecular) It's not always: Na + Cl --> NaCl (which is ionic)
How would you prepare a 300 ml of a 0.1 M Na CL solution from a solid Na CL solution and water?
You prepare a solution by dissolving a known mass of solute into a specific amount of solvent. In solutions, M is the molarity, or moles of solute per liter of solution. For 300 ml of a 0.1 M Na CL solution from a solid Na CL solution and water you need water and sodium chloride.
What bonds is the strongest Na-I or Na-Cl or K-I or K-Cl?
In neurons, ________ ions are at higher concentration inside the cell and ________ ions are at higher concentration in the extracellular fluid. A) Cl; organically bound B) Cl; K C) K; Na D) Cl; Na E) Na; K
What is the chemical equation for NaCl and H2O?
Sodium chloride is dissolved and dissociated in water as follow: NaCl-----------------Na+ + Cl-
What is the molecular formula for NaCl dissolving into water?
Sodium chloride is dissociated in water: NaCl---------------Na+ + Cl-
What are the formula weight of NaCl and BaCl2?
The molecular weight of NaCl is 58.44g/mol, the atomic mass of Na is 22.99 and the atomic mass of Cl is 35.45 when added together we get 58.44 g/mol.The molecular weight of BaCl2 is 208.233g/mol, the atomic mass of Ba is 137.327 and the atomic mass of Cl2 is (35.453)(2) = 70.906 when added together we get 208.233g/mol
What is the molecular mass of Cl 2?

What is the reaction of Na Cl -- Na-Cl?
NaCl-----------------Na+ + Cl-is a dissociation reaction.
Can atomic and molecular ions be cations or anions?
Yes. Example of atomic cation is Na+. Example of atomic anion is Cl-. Example of molecular cation is NH4+. Example of molecular anion is NO3-.
Exaplin why structural formulas cannot be ionic substances?
Structural formulae are usually used to describe covalent molecular compounds. It is illogical to use structural formulae to describe ionic compounds because ionic compounds are typically lattice structures. This means that they are electrostatically fixed to one another, and what would normally be considered molecules run together as ions bond to multiple other ions. For example, NaCl would not look like: Na+-Cl- But rather- (Na+)-(Cl-)-(Na+)-(Cl-)- (etc.) (Cl-)-(Na+)-(Cl-)- (Na+)-etc (Na+)-(Cl-)-(Na+)-(Cl-)- (etc.) etc.- etc- etc- etc
What is the percentage composition of NaCl?
Calculate the percent by weight of sodium (Na) and chlorine (Cl) in sodium chloride (NaCl) * Calculate the molecular mass (MM):MM = 22.99 + 35.45 = 58.44 * Calculate the total mass of Na present:1 Na is present in the formula, mass = 22.99 * Calculate the percent by weight of Na in NaCl:%Na = (mass Na ÷ MM) x 100 = (22.99 ÷ 58.44) x 100 = 39.34% * Calculate the total mass of Cl present:1 Cl is present in the formula, mass = 35.45 * Calculate the percent by weight of Cl in NaCl:%Cl = (mass Cl ÷ MM) x 100 = (35.45 ÷ 58.44) x 100 = 60.66% The answers above are probably correct if %Na + %Cl = 100, that is,39.34 + 60.66 = 100.
What are the most likely particles present in Na Cl solutions and in sucrose solutions?
In water? If so - salt solution - the fllowing hydrated ions - H+, OH-, Na+, Cl- plus molecular H2O. Sugar solution - hydrated sugar molecules, molecular H2O and H+ and OH- hydrated ions
Is the product of a combination reaction is always a molecular compound?
No, while sometimes it can: 2 H2 + O2 --> 2 H2O (molecular) It's not always: Na + Cl --> NaCl (which is ionic)
What is the mass ratio of Na to Cl in sodium chloride?
The ratio mass of chlorine/mass of sodium is 1,5.
What is the mass of two moles of NaCl?
2 * [(Na=23) + (Cl=35.5)] = 117 grams NaCl
