Answer:
0.726 mol·L⁻¹
Step-by-step explanation:
c = moles/litres
=====
Moles = 29.8 × 1/342.30
Moles = 0.087 06 mol
=====
Litres = 120 × 1/1000
Litres = 0.120 L
=====
c = 0.087 06/0.120
c = 0.725 mol·L⁻¹
Answer:
Your hypothesis is incorrect because warm substances rise when in a colder environment. The correct hypothesis would be : "If the 2 chambers of water are poured side by side, the warmer water will float above the cooler layer because warm water rises and cold water sinks."

Explanation:
>> ice is solid
>> water is liquid
>> Steam is gas
>> Ice → water = melting
>> water → steam = evaporation
>> steam → water = condensation
>> water → ice = freezing
The lysis reaction with the formation of two different gases, and the synthesis reaction with the reaction of hydrogen and oxygen support that water is a compound and not an element.
<h3>What is electrolysis?</h3>
The electrolysis is the analytical process for the separation or the deposition of the element in the presence of the electric field.
The passing of electric current through water results in the release of two types of gases. Thus, it can be said that water lysis or breakdown forms the release of two elements hydrogen and oxygen supporting the fact that water is a compound and not an element.
The production of water is found to be formed with the reaction of hydrogen with oxygen. Thus it supports that water is a compound and, not an element.
