Answer:
a) The lewis dot structure is shown in the image attached to this answer
b) The formal charge on each of the atoms is zero
c) bromine has an oxidation state of +5 while fluorine has an oxidation state of -1
d) 90 degrees
e) Square Pyramidal
f) polar bonds
g) polar molecule
Explanation:
The molecule BrF5 has a formal charge of zero. It exhibits an sp3d2 hybridization state with a square pyramidal geometry. The bond angle in the molecule is 90 degrees. It is a molecule of the type AX5E. The oxidation state of bromine is +5 while that of fluorine is -1.
The Br-F bonds are polar. The overall molecule is polar due to asymmetric charge distribution concentrating on the central atom since the molecule is square pyramidal.
Answer:
c.I ,II & IV are correct
Explanation:
Phenolphthalein is an indicator. An indicator is an organic dye whose solution changes colour as the concentration of hydrogen ions in solution changes.
Hence a typical indicator exhibits different colours at different pH ranges. The colour of an indicator in an acid, a base and at end point always differs.
Phenolphthalein is a colourless solution which has a pink colour in an alkaline medium and colourless in an acidic medium.
Seeds, because angiosperms seeds are in flowers.
Explanation: When Iron(III) nitrate reacts with lithium hydroxide in their aqueous state produces Iron (III) hydroxide and Lithium nitrate in their aqueous state.
Balancing a chemical reaction: In a chemical equation, the total number of atoms and total charge on every element remains same on both reactant and product side.
Balanced Chemical reaction will be:
