2. A sample of apple juice has a volume of 4 mL and a mass of 72 g. What is the density
tangare [24]
  • Mass=72g
  • Volume=4mL

\\ \sf\longmapsto Density=\dfrac{Mass}{Volume}

\\ \sf\longmapsto Density=\dfrac{72}{4}

\\ \sf\longmapsto Density=18g/mL

How can you use a heating curve to find the melting and boiling point
lana66690 [7]

Answer:

Explanation:

A heating curve graphically represents the phase transitions that a substance undergoes as heat is added to it. ... The first change of phase is melting, during which the temperature stays the same while water melts. The second change of phase is boiling, as the temperature stays the same during the transition to gas.

For The Reaction CH3COOH ---> CH3COO- + H+, which of the following statements is true? A.) Ch3COOH is a Bronsted Lowry base.
Savatey [412]

Answer: Option (C) is the correct answer.

Explanation:

According to Arrhenius, bases are the species which when dissolved in water will give hydroxide ions, that is, OH^{-}.

For example, NaOH + H_{2}O \rightarrow Na^{+} + OH^{-}

Arrhenius acids are the species which when dissolved in water will give hydrogen ions, that is, H^{+}.

For example, CH_{3}COOH + H_{2}O \rightleftharpoons H_{3}O^{+} + CH_{3}COO^{-}

In water, when an acid loses a hydrogen ion then the specie formed is known as conjugate base.

Here, CH_{3}COO^{-} is the conjugate base of CH_{3}COOH.

Similarly, species which accept the hydrogen ion result in the formation of conjugate acid.

Hence, H_{3}O^{+} is the conjugate acid of H_{2}O.

Thus, we can conclude that CH_{3}COO^{-} is the conjugate base.
