Answer:
Explanation:
Aluminium hydroxide () is a base and hydrobromic acid (HBr) is a strong acid.
Hence an acid-base reaction occurs between and HBr
Balanced molecular equation:
Balanced total ionic equation:
Balanced net ionic equation:
(net ionic equation is written by removing common ions present in both side of total ionic equation)
In science, we have a name for this, called Avogadro's number, and it describes the number of representative particles in one mole of a substance. The inverse mole unit tells us there are 6.022×1023 particles of something *per mole* so there are 1,023 particles
Answer:
All of the choices.
Explanation:
As the reaction is involving with a mixture of H₂O and CH₃OH, these two reagents can work as nucleophyle of the reaction. Both of them, are polar and promoves a Sn1/E1 reaction. When it reacts with water it will produce product B); it will form product C) when it reacts with methanol, and product A) will be formed when the reaction undergoes an E1 reaction.
In this case, the only way to show you this, it's doing the mechanism of reaction for each product. Picture attached show the mechanism for the formation of all these products.
Answer:
C.
Explanation:
Objects and liquids float on liquids of a higher density and sink through liquids of lower density. the water and corn starch sank under the oil as well so that means they are denser. The paper clip sank through all three liquids also. Hence, the answer would be the clip is denser than the three liquids, and water is denser than oil.
Most nonpolar molecules<span> are water-insoluble, which make them </span>hydrophobic.
