Is rubidium chloride an ionic compound?
Yes, rubidium chloride is an ionic compound. It is formed by the ionic bonding between rubidium, which donates an electron to become a cation, and chloride, which accepts an electron to become an anion.
Why is mercury chloride soluble but lead chloride is insoluble?
Mercury (II) chloride is soluble, but Mercury (I) (mercurous) chloride is insoluble. The formula of the first compound is HgCl2, and mercurous chloride is Hg2Cl2. Also, lead chloride (PbCl2) and Silver chloride (AgCl) is insoluble. All other chloride solutions are soluble.
What ionic compound will lower the freezing point the most if 1 mol of it is added to 1 L of water?
A compound that dissociates into more ions when dissolved in water will have a greater freezing point depression. For example, calcium chloride (CaCl2) will lower the freezing point more than sodium chloride (NaCl) because it dissociates into three ions (Ca2+ and 2Cl-) compared to sodium chloride, which dissociates into two ions (Na+ and Cl-).
How does dissolving an ionic compound in water increase electrical conductivity?
When an ionic compound dissolves in water, its ions dissociate and become free to move. These charged ions can conduct electricity by carrying electric current through the solution. The higher the concentration of dissolved ions, the greater the conductivity of the solution.
How can one determine conductivity in a substance?
Conductivity in a substance can be determined by measuring its ability to conduct electricity. This can be done using a conductivity meter, which measures the flow of electrical current through the substance. Higher conductivity indicates a greater ability to conduct electricity.
What is the binary compound of AlCl?
AlCl3Although a metal-nometal compound, AlCl3 is not ionic (as might be predicted). Single covalent bonds form between aluminum and three chlorine atoms, forming AlCl3 molecules. Two of these join together (forming a 'dimer') with formula Al2Cl6. Aluminium bromide and aluminum iodide are similar in nature. However, aluminum fluoride is ionic. Why the difference in bonding? It all has to do with the difference in electronegativity of the elements:Al & F - difference of 2.37Al & Cl - difference of 1.55Al & Br - difference of 1.35Al & I - difference of 1.05Generally, if the difference in electronegativity is greater than 2.0 then the bond will be ionic. If less than 2.0, then the bond will be covalent.
Is rubidium chloride an ionic compound?
Yes, rubidium chloride is an ionic compound. It is formed by the ionic bonding between rubidium, which donates an electron to become a cation, and chloride, which accepts an electron to become an anion.
Why is the melting point of sodium chloride is much higher than that of aluminium tetrachloride?
Sodium chloride is an ionic compound whereas AlCl3 is a covalent compound. Ionic compounds have greater melting point due to stronger electrostatic force of attraction.
How much of this compound alcl3 you are going to obtain if you have a reaction of 385 g aloh3 with 256 g hcl you also must indicate the limiting reactant balance aloh3 3 hcl - alcl3 3 h2o?
The reaction equation with conventional capitalization is: Al(OH)3 + 3 HCl -> AlCl3 + 3 H2O. The gram formula unit masses are 78.00 for aluminum hydroxide, 133.34 for aluminum chloride, 36.46 for hydrogen chloride, and 18.015 for water. Therefore, the relative mass ratios are (78.00) to [3(18.015)] or about 1.443 for the ratio of the two reactants. The mass ratio of the specified available amounts of the two reactants is 385/256 or about 1.503, which is greater than the theoretical amount. Therefore, the limiting reactant is HCl. The stoichiometric reactant mass ratio of aluminum chloride to hydrogen chloride is about 133.34/(3)(36.46) or about 1.219. Therefore, a fully reacted amount of 256 g of hydrogen chloride will produce about (1.219)(256) or about 312 g of aluminum chloride. (The provided data for masses has three significant digits, so that the answer should also have three significant digits.)
Which is better condutor iron or mercury?
The electrical conductivity of iron is greater.
Why is mercury chloride soluble but lead chloride is insoluble?
Mercury (II) chloride is soluble, but Mercury (I) (mercurous) chloride is insoluble. The formula of the first compound is HgCl2, and mercurous chloride is Hg2Cl2. Also, lead chloride (PbCl2) and Silver chloride (AgCl) is insoluble. All other chloride solutions are soluble.
What do you mean by molten sodium chloride?
This is sodium chloride at a temperature greater than 801 0C.
What ionic compound will lower the freezing point the most if 1 mol of it is added to 1 L of water?
A compound that dissociates into more ions when dissolved in water will have a greater freezing point depression. For example, calcium chloride (CaCl2) will lower the freezing point more than sodium chloride (NaCl) because it dissociates into three ions (Ca2+ and 2Cl-) compared to sodium chloride, which dissociates into two ions (Na+ and Cl-).
Is CaCl2 nonpolar or polar?
CaCl2 is a polar compound. In CaCl2, the calcium cation has a net positive charge, while each chloride anion has a net negative charge, leading to an overall dipole moment and making the molecule polar.
How does dissolving an ionic compound in water increase electrical conductivity?
When an ionic compound dissolves in water, its ions dissociate and become free to move. These charged ions can conduct electricity by carrying electric current through the solution. The higher the concentration of dissolved ions, the greater the conductivity of the solution.
Why efficiency is greater then 1 in case of compound lever?
why efficency is greater than 1 in case of compound lever
How are conductivity and concentration of a salt solution related?
The greater the concentration of salt in an aqueous solution, the higher the electrical conductivity. This is because, with a greater salt concentration, there are more ions available to serve as a path for electron transfer in the solution.
