Which of the following is NOT a property of a base?
inna [77]

Bases turns cabbage juice yellow or green is not a property of bases.

<u>Explanation:</u>

As per the property of the bases, the correct statements are:

  • The taste of the bases are bitter.
  • Solutions of bases are slippery in nature
  • Bases reacts with the metals to form hydrogen gas and a salt.
  • For example, sodium hydroxide reacts with zinc metal to form sodium zincate salt and hydrogen gas.

Wrong statement:

  • It turns cabbage juice yellow or green, whereas it turns the cabbage juice blue or green and acids turns cabbage juice red or pink.

Bobby found that water has a high boiling point and concluded this was because water intermolecular forces. Based on the data, i
Art [367]

Yes, Bobby is correct

Explanation:

Anomalously high boiling point of water is as a result of the intermolecular forces between the molecules of water.

The intermolecular forces found in water are the very strong hydrogen bonds.  The bulk of the physical properties of matter are due to the intermolecular forces that they possess.

  • Hydrogen bonds are stronger than van der waals forces and they are more effective in binding molecules together into larger units.
  • Substances whose molecules join via hydrogen bonds have higher boiling points i.e lower volatility than those with van der waals forces.
  • Hydrogen bond is actually an electrostatic attraction between hydrogen atom of none molecule and the electronegative atom(O or N or F) of a neighboring molecule.

What mass of water would be produced if 1.5 g of ethanoic acid was reacted completely with sodium hydroxide (3 marks)
Zigmanuir [339]

Mass of water : 0.45 g

<h3>Further explanation</h3>

Given

1.5 g ethanoic acid

Required

Mass of water

Solution

Reaction

<em>CH₃COOH + NaOH ⇒H₂O + CH₃COONa</em>

mol CH₃COOH(MW=60 g/mol) :

= mass : MW

= 1.5 : 60

= 0.025

mol H₂O from the equation :

= 0.025(mol ratio CH₃COOH : H₂O= 1 : 1)

Mass of water :

= mol x MW water

= 0.025 x 18 g/mol

= 0.45 g

What is a molar solution?
mina [271]

Answer:

Molar concentration is a measure of the concentration of a chemical species, in particular of a solute in a solution, in terms of amount of substance per unit volume of solution. In chemistry, the most commonly used unit for molarity is the number of moles per liter, having the unit symbol mol/L or mol/dm³ in SI unit.
