Answer:
A is a physical change, no atoms are being lost its still in it original form
B is a chemical change, it is losing atoms and changing into a new substance
Explanation:
Answer:
2.71×10²⁴ particles
Explanation:
Applying Avogadro's constant
Avogadro's constant states that, The number of specified particles contained in a mole of a substance is equal to 6.02×10²³.
From the question,
If one mole of chlorine contains a particle of 6.02×10²³,
Therefore,
4.5 moles of chlorine will contain a particle of (4.5× 6.02×10²³)
⇒ 27.09×10²³
Hence the number of particle contained in 4.5 moles of chlorine ≈ 2.71×10²⁴ particles
Answer:
A(yellow) = 52
Explanation:
A(yellow) = A(total) - A(red)
= 11×6 - 7×2
= 66 - 14
= 52
Answer:
water spreads the spicy taste around your mouth, while milk does not and it helps the hot taste go away.
Explanation:
Answer:
The chemistry of iron is dominated by the +2 and +3 oxidation states i.e. iron(II) and iron(III) complexes e.g. Fe2+ and Fe3+ complex ions with selected ligands, usually of an octahedral shape, a few tetrahedral iron(III) complexes are mentioned too. The reactions of the aqueous ions iron(II) and iron(III) with ammonia, sodium hydroxide and sodium carbonate are described and explained as are complexes of iron(III) with the chloride ion and cyanide ion.
