Is PF5 ionic or covalent?
Is PF5 ionic or covalent?
Any “extra” bonds are ionic in character with the extra electrons assigned to the outer atoms. In this case, they do not exceed the octet rule. With this model we can draw a series of resonance structures as shown below for PF5. Thus, PF5 has net four covalent bonds and one ionic bond.
Is pcl3 an ionic bond?
Phosphorus trichloride. Covalent bonding. Strong electrostatic forces of attraction between positively charged nucleus and shared pair of valence electrons. Both phosphorus and chlorine are non metallic elements.
What is the correct name for SO3?
Sulfur trioxide
What happens when SO3 passed through water?
When sulphur trioxide is passed through water. It produces sulphuric acid.
Why is so3 not added directly to water?
The correct answer of this question is option ‘c’, sulphur trioxide is not directly dissolved in water to form sulphuric acid because it results in the formation of dense fog of sulphuric acid which is difficult to condense.
What happens when concentrated H2SO4 is added to calcium fluoride?
When concentrated H2SO4 is added to calcium fluoride. It produces calcium sulphate and hydrogen fluoride.
What happens when conc H2SO4 is added to CU?
When copper is heated with concentrated sulphuric acid. Concentrated sulphuric acid is an oxidising agent . Complete answer: When copper reacts with concentrated sulphuric acid sulphur dioxide is produced by the reduction of H2SO4.
Does dilute Sulphuric acid reacts with copper?
Solution: (a) Copper does not react with dilute sulphuric acid. So, no reaction will take place when diluting sulphuric acid is poured onto a copper plate. But when concentrated sulphuric acid is poured onto a copper plate, effervescence is observed.
Why does Connor not liberate hydrogen on readme with dilute Sulphuric acid?
A more reactive element can displace a less reactive element from its salt solution. The metals above hydrogen in the activity series react with dilute sulphuric acid and dilute hydrochloric acid to liberate hydrogen. The metals below hydrogen in the activity series cannot do that. Copper fall below hydrogen in series.
Why does silver not evolve hydrogen on reacting with dilute Sulphuric acid?
Silver is less reactive than hydrogen and so placed below hydrogen in the reactivity series. Metals which are less reactive than hydrogen cannot displace hydrogen from acids. So, when silver metal is added to dilute HSO, no reaction takes place. …
Which metal will not liberate hydrogen from dilute h2so4?
Cu is below hydrogen in the electrochemical series, so cannot liberate H2 from dilute H2SO4.
Which metal does not liberate hydrogen from dilute acid?
Copper
