Answer:
2. Translucent
4. Reflection
Explanation:
The terms translucent describes the nature of the juice and reflection perfectly fits the property of the light.
A translucent substance is one that partially allows light to pass through it. Since it is said that some of the light bounced back and some passed through, this is translucent.
Also, the light bouncing back is an indicator of reflection. Reflection is a property of light where it bounces back a surface.
The initial number of moles of the unknown acid (HA) is equal to the final amount of the number of moles of the known base (NaOH) because they fully consumed each other.
<h3>What is neutralization reaction?</h3>
Neutralization reactions are those reactions in which acids and bases reacts with each other for the formation of water and salt.
Acids reacts with base to form salt means all gets consumed by each other so the initial moles of an unknown acid is equal to the final moles of the known base.
And reaction between them is shown as:
HA + NaOH → NaA + H₂O
Hence acids and bases fully consumed each other that's why we can calculate the moles of unknown substance.

To answer this question, we must first look at the
reactivity series table. From the table, we can see that those which are
located above are the most reactive while those below are less reactive. Which
means that elements cannot replace those elements which are above them.
From the series, platinum is below lead, hence there will
be no reaction.
Answer:
No reaction
First, we determine the energy released by the reaction using the heat capacity and change in temperature as such:
Q = cΔT
Q = 32.16 * 0.42
Q = 13.51 kJ
Next, we determine the moles of ammonia formed as the heat of formation is expressed in "per mole".
Moles = mass / molecular weight
Moles = 5/17
Moles = 0.294
Heat of formation = 13.51 / 0.294
The heat of formation of ammonia is 45.95 kJ/mol
