Answer:
defined as a process in which mo heat transfer take place
Explanation:
is a process which occurs without transferring heat /mass between the system and it's surrounding.
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
Every single person in any scientific field that uses chemistry
Answer:
this probably won't be much help the answer is
Explanation:
comes from the ice will eventually have the same temperature ... temperature of the ice cube. ... Heat is always the transfer of energy from an object at a higher. hope this helps
Energy can be conserved by efficient energy use.
Answer: Option A
<u>Explanation:</u>
Energy can be transferred from one form to another, but it cannot be destroyed or created. So it can be conserved if efficiently used. Thus efficient usage of energy lead to conservation of energy. Due to conservation of energy, the forces can be renewable and non-renewable.
So, we should know how the input energy can be completely converted to another form of energy leading to efficient usage of energy without any loss. As if there is no loss, input energy will be equal to output energy leading to 100% efficiency.
