They used mainly the Corinthian style‚ but they also made combinations‚ for instance the Corinthian-Ionic style. The Romans also added a lot of details and decorations to their temples. The Romans also made what became the very common round‚ domed temple. The main temple of a Roman city was the capitolium. The Pantheon‚ the famous temple in Rome‚ was

Ionic compounds do not conduct electricity in solid form but their aqueous solution conduct electricity. Why? Or Common salt does not conduct electricity but its aqueous solution conduct electricity. Why? Ans. Ionic compounds (e.g.- Common salt) have strong electrostatic forces of attraction between their constituent ions. Thus ions are strongly held and cannot

When you encounter net ionic equations on the SAT II Chemistry test‚ you’ll need to remember the following solubility rules‚ so memorize them! Also keep in mind that net ionic equations‚ which are the bare bones of the chemical reaction‚ usually

permeable to K. 3. Does any net Ionic current flow at the resting potential? What are the relationships among “passive" and “pump”ionic currents at the resting potential? There is no net ionic current flow at the resting potential. However‚ since neither Na+ nor K+ is at equilibrium‚ there is a net flow of each across the membrane. The Na-K pump generates the concentration difference that sustains the resting potential: but it is the passive ionic flow that creates the resting potential
