Answer:
undergo death as result of the water loss from cell
Explanation:
The ingredients such as honey, jellies, Jams, preserves and other food which have high sugar content are contaminated hardly by the bacteria because due to the presence of high amount of the sugar and carbohydrates, the solution of the them becomes hypertonic in nature and if a bacteria acts on such solution, the result is the loss of the water from their cell and ultimately the bacteria dies. So, they remain fresh even if their containers are left open at the room temperature.
Base on the problem given, it shows that the rate law for this reaction is directly proportional. The relationship between the reactants Z and Y that is proportional to the cube of [Z], it shows the concentrations of reactants is expressed by the rate law.
The (w/v)% concentration of vinegar contains 5g of acetic in 100mL of solution is approx 0.5 %
<h3>What is Concentration ?</h3>
The concentration of a chemical substance expresses the amount of a substance present in a mixture.
There are many different ways to express concentration.(w/v)% is one of them.
Given ;
- Mass of solute(acetic acid) is 5.0 g
- Volume of solution is 100.0 mL.
We need to convert the grams of acetic acid to moles ;
Formula of acetic acid is CH₃COOH
Thus,
Molar mass of acetic acid = 2(12.01) + 4(1.01) + 2(16)
= 24.02 + 4.04 + 32
= 60.06 grams per mol
Moles of acetic acid = 5.0/60.06
= 0.083 moles
(w/v)% = 0.083 x 60 / 1000 x 100
= 0.498 %
= 0.5 %
Hence, The (w/v)% concentration of vinegar contains 5g of acetic in 100mL of solution is approx 0.5 %

<u>Answer:</u> Electrons are taken up by 
and they are lost by 
<u>Explanation:</u>
Redox reaction is defined as the reaction in which oxidation and reduction take place simultaneously. It is also called the reaction where the exchange of electrons takes place.
An oxidation reaction is defined as the reaction in which a chemical species loses electrons takes place. In this reaction, the oxidation state of a substance gets increased.
A reduction reaction is defined as the reaction in which a chemical species gains electrons takes place. In this reaction, the oxidation state of a substance gets reduced.
For the given chemical reaction:
The half-reactions for this redox rection follows:
<u>Oxidation half-reaction:</u> 
<u>Reduction half-reaction:</u> 
Hence, electrons are taken up by and they are lost by
