Answer: 0.714 M
Explanation:
Molarity of a solution is defined as the number of moles of solute dissolved per Liter of the solution.
According to the neutralization law,
![M_1V_1=M_2V_2](https://tex.z-dn.net/?f=M_1V_1%3DM_2V_2)
where,
= molarity of stock solution = 1.00 M
= volume of stock solution = 1.00 L
= molarity of dilute solution = ?
= volume of dilute solution = (1.00+0.40) L = 1.40 L
![1.00\times 1.00=M_2\times 1.40](https://tex.z-dn.net/?f=1.00%5Ctimes%201.00%3DM_2%5Ctimes%201.40)
![M_2=0.714M](https://tex.z-dn.net/?f=M_2%3D0.714M)
The concentration of a 1.00 M solution of sodium chloride (NaCl) after exactly one liter of the solution is mixed with 0.40 L of water is 0.714 M

Answer:
limiting Reactant
Explanation:
In a chemical reaction, the limiting reagent, or limiting reactant, is the substance that has been completely consumed when the chemical reaction is complete.
1. No two magnetic lines intersect
2.They always form closed loops
3. Outside they seems to travel from north to south and inside south to north
4. It is vector quantity.
Answer:
Explanation:
Heat can transfer between objects in two different ways. Generally, heat will travel from places of higher heat to places of lower heat.
The first is conduction. This is when the object being heated and releasing heat are in direct contact. Not as much heat is lost in this process, since the thermal energy has nowhere else to go except for the object it is touching. An example would be putting a kettle on a hot stove, but it could also be grabbing a cold pole with your relatively warm hands.
The second is convection. This is where heat is radiated into the air, and thus, transferred by the air, to another object. The actual heat that you feel is actually electromagnetic waves, and its transfer from an object is called electromagnetic radiation. Convection is the heat you feel from a near fire or a space heater. This is also why wind is present in our atmosphere.
There is also radiation. This is caused from the burning or breaking down of a substance. This might come from the sun.
