1066.7 ml of the stock solution must start with, preparing 2.00 L of a 0.800 M NaNO3 solution.
<h3>What is volume?</h3>
Volume is the space occupied by a three-dimensional object.
By the formula 
M1 is the initial molarity, 1.5 M
M2 is the final molarity, 0.800 M
V1 is the initial volume
V2 is the final volume, 2.00 L
Putting the values in the equation

Thus, the initial volume is 1066.7 ml

I'd say it's partially dissociating into products
Answer:
Before we get into the first law of thermodynamics we need to understand the relation between heat and work and the concept of internal energy. Just like mass, energy is always conserved i.e. it can neither be created nor destroyed but it can be transformed from one form to another. Internal energy is a thermodynamic property of the system that refers to the energy associated with the molecules of the system which includes kinetic energy and potential energy.
Whenever a system goes through any change due to interaction of heat, work and internal energy, it is followed by numerous energy transfer and conversions. However, during these transfers, there is no net change in the total energy.
Similarly, if we look at the first law of thermodynamics it affirms that heat is a form of energy. What it means is that the thermodynamic processes are governed by the principle of conservation of energy. The first law of thermodynamics is also sometimes referred to as the Law of Conservation of Energy
Explanation:
Answer:
F. a dark solid formed on the zinc.
-Is because when the solid is formed it is called the "precipitate", which is commonly know as chemical reaction.
