Answer:
Pollen

bc i take notes and also my sister studies bio

Simple molecules have no overall charge, or charged particles that can separate, so simple molecular substances cannot conduct electricity, even when liquid or dissolved in water.
In this reaction
ester is reduced to
aldehyde. Such reduction can not be achieved by reacting reducing agents like
LiAlH₄ because it will further reduce aldehydes to alcohols. So, in order to stop reduction at alddehyde, ester is reacted with bulky reducing agent, <span>
Diisobutylaluminium hydride (DIBAL) which works with same mechanism as that LiAlH</span>₄ do. It also add hydride to carbonyl group. The reaction is shown below,
Answer:
1.51 X 10^23 ions
Explanation:
The number of ions in 17.1 gm of aluminum sulphate Al2 (SO4)3 =….. [Molar mass of Al2 (SO4)3 = 342 gm]
in one molecule of Al2(SO4)3 there are 5 ions 2 aluminum and 3 sulfate ions
in 2 molecules there are 2X5= 10 ions
in 10 molecules there are 10X5 = 50 ions
molar mass of Al2(SO4)3 = (2 X 26.98) +( 3 X 32.1) + (3 X 4 X 16.0 ) =342.gms = 17.1/342 =0.0500 moles
1 mole =6.02 X 10^23 molecules ( see Avogadros number)
0.0500 moles = 0.0500 X 6.02 X 10^23 molecules =
0.301 X 10^23 molecules = 3.01 X 10^22 molecules
We determined that each molecule of Al2(SO4)3 has 5 ions
so 3.01 X10^22 molecules have 5 X 3.01 X 10^22 ions =
15.05 X 10^22 ions = 1.51 X 10^23 ions
Answer:
True
Explanation:
Pi bonds are formed using p orbitals. Atoms that have p orbitals have 3 of them. In an sp² hybridized atom, only 2 of the 3 p orbitals are being used in the sp² orbitals, leaving one p orbital free for pi bonding. Therefore, only one pi bond can be formed to an sp² hybridized atom.
