Answer:
A neutralization reaction between an acid and a metal hydroxide produces salt and water.
Explanation:
In a neutralization reaction, an acid and a base are combined according to the following example (hydrochloric acid and sodium hydroxide):
HCl + NaOH ---> H20 + NaCl
They are generated as products: water and a salt, in this case sodium chloride.
Explanation:
Ethanethiol is an organosulphur compound which had an alkyl group(CnH2n+1) and a -thiol group (-SH). A thiol group like an hydroxyl group has its Oxygen replaced with sulphur.
Ethanethiol shows little association of its -SH group with the water molecules by hydrogen bonding; both with water molecules and among themselves. Hence why they are less soluble in water or slightly soluble in water.
Ethanol is an organic compound which the general formula of CnH2n+1OH. Ethanol is soluble in water because of the reaction of the -OH group with the water molecules to form hydrogen bonds.
Note that as the alkyl chain increases, Solubility decreases. This is because the alkyl chain forms the hydrophobic surface of the molecule due to its non-interaction of the water molecules to form hydrogen bond.
Sn2+
Your protons equal the atomic number of an element: Sn (Tin).
The amount of protons and electrons will be the same if the atom is neutral. In this case, tin has lost two electrons and so tin is no longer neutral and becomes Sn2+
To double check, you would subtract the atomic number from the mass number of tin to see if the number of neutrons is equal to what has been provided.
mass number - atomic number = number of neutrons
118 - 50 = 68
Answer:
False
Explanation:
The increase in the temperature of a liquid also increases the rate of evaporation, as the same for the other way around. As intermolecular force increase rate of evaporation decreases. This happens because intermolecular force make it less likely for the molecules on the surface to escape from liquid and become vapour gas. As temperature increases rate of evaporation increases.
You can do this by dividing by the molar mass of Zn:
