When aqueous solutions of sodium acetate and hydroiodic acid are mixed, an aqueous solution of sodium iodide and acetic acid results. Write the net ionic equation for the reaction. Solution Net ionic equation will represent equation without spectator ions Balanced chemcial equation Na(CH 3 COO) + HI ---------------------------> NaI + CH3COOH ionic equation Na + (aq) + CH3COO - (aq) + H + (aq) + I - (aq) ------------------------> Na + (aq) + I - (aq) + CH3COO - (aq) + H + (aq) since all are spectator ions there is no net ionic equation .

When equal moles of the following acids are dissolved in 1 L of H 2 O, which acidic solution will have lowest concentration of ions? HI HF HClO4 HNO 3 HCl Please explain why! Solution All the acids given are the strongest acids. But among all, HI > HBr > HClO 4 > HCl > HNO 3 The above order it the acidic strength. Among all the given acids, HI is the strongest and HNO3 is the weakest. Strongest acid dissociates completely in H 2 O (There will not be any undissociated molecule). But due to the common ion effect(H + ), the HNO 3 acid will have lowest concentrations of ions. Thanks and hope u got the answer. .

When discussing the security of SSO systems, which of the following is considered a disadvantage? A. Single sign-on requires much more maintenance and overhead because all systems are tied together. B. The biggest disadvantage to single sign-on is that system time on all systems must be held to very tight standards; if deviated from, this can cause serious access problems. C. There are no real disadvantages to single sign-on. D. If single sign-on is breached, it offers the intruder access to all systems tied to the SSO implementation Solution D. Single sign-on (SSO) offers the attacker potential access to many systems tied to SSO when authenticated only once. .

When a liquid is placed in a sealed container, A) a set vapor pressure will be reached, which is the same at all temperatures. B) once equilibrium is established between the liquid and the vapor, the rate of the evaporation process will equal the rate of condensation. C) condensation of the evaporated molecules in the jar can only occur once all of the liquid molecule are in the vapor (or gaseous) state. D) evaporation of the liquid cannot occur. E) all molecules stay in the liquid state. Solution Correct answer is (B) once equilibrium is established between the liquid and the vapor, the rate of the evaporation process will equal the rate of condensation. .

When a hydrate compound is heated, does the water get broken down into its component elements? When a hydrate compound is heated, does the water get broken down into its component elements? Solution No, when a hydrate is heated, water does not broken down into its components. When a hydrate is heated it decompose into anhydrous salt and water evaporates and change into vapour. It is a reversible process it can be get back after adding some water in it. .

What will happen to the Ksp value of Al(OH)3 when sodium hydroxide is added to the solution? Explain why Without doing a calculation, predict which of the following has the greatest molar solubility in water? AgCl (Ksp = 1.8 x 10^-10) AgBr (Ksp = 5.0 x 10^-13) AgI (Ksp = 8.3 x 10^-17) Solution 1) Solubility equation of Al(OH)3 is: Al(OH)3Â Â <â€”>Â Â Al3+Â Â (aq) + 3 OH- (aq) Adding NaOH is like adding product (OH-) Adding product will shift the reaction in the direction of reactant as per Le chatelier Principle So, Equilibrium moves to reactant side This will decrease solubility Answer: solubility decreases 2) All of them are of same form AX So, the one with the greatest value of Ksp will have greatest molar solubility Answer: AgCl .

Which of the following can be used to create a VPN (Virtual Private Network)? A. PPP (Point-to-Point Protocol). B. PPTP (Point-to-Point Tunneling Protocol). C. SLIP (Serial Line Internet Protocol). D. ESLIP (Encrypted Serial Line Internet Protocol). Solution B. PPTP (Point-to-Point Tunneling Protocol). Tunneling refers creating a virtual dedicated connection between two systems or networks. You create the tunnel between the two ends by encapsulating the data in a mutually-agreed-upon protocol for transmission. In most tunnels, the data passed through the tunnel appears at the other side as part of the network. Point to point tunneling protocol was originally proposed by Microsoft and its associates and it works by embedding its very own network protocol within the TCP/IP packets. .

What type of intermolecular forces exist in NH3 and H2S? dispersion forces, dispersion forces and H-bond, dispersion forces & dipole-dipole forces Solution In NH 3 ,intermolecular forces present are hydrogen bonds . The hydrogen bonds are many magnitudes stronger than other intermolecular forces in NH 3 . In H 2 S , Sulfur atom have 6 valency electrons and hydrogen atoms have 2 valence electrons. The central sulfur atoms has 4 entities around it. Two hydrogen atoms, and two lone non-bonding electron pairs. According to VSEPR theory, this means that the shape of the molecule is bent and because of the asymmetrical shape, the molecule is polar.The intermolecular force which polar molecules take part in are d ipole-dipole forces . .

Which molecule(s) will experience the London force? Select all that apply. Solution The London force is the weakest intermolecular force. The London dispersion force is a temporary attractive force that results when the atom forms tempory dipole moment as NH3 and H2O have permanent dipole moment so they will not experience London force. where N2 and H2 doesn\'t possess any permanent dipole moment so in N2 and H2 atoms, the tempory dipole moment can be formed so they can experience London force the answer is N2 and H2 .
