Number of moles = 2.25 mols
volume <span>of the solution = 3.00 L
</span>
Therefore :
molarity = moles / volume
m = 2.25 / 3.00
=> 0.75 M
1 is the answer to your question
Answer:
Explanation:
Given that,
The heat capacity of solid iron is 0.447 J/g°C.
Mass, m = 450 g
Initial temperature,
Let the heat transferred, Q = 65 kJ
We need to find the final temperature. The heat transferred is given by :
So, the final temperature is .
Answer:
Explanation:
Here, we want to get if the presented question could be answered by science or not
Looking at the question, we can see it has to do with legislation. The underlying question of if the substances released are harmful could be answered by science. However, after determining the harmful nature of these releases. The required legislation is something that science has nothing to do with
Thus, we can see penalization after discovery of the harmful nature is not a question for the sciences
Answer:
According to Boyle's law, the volume of a gas is inversely proportional to its pressure if the temperature and number of particles are constant
Explanation:
Number of moles: constant
Temperature: constant
Volume is inversely proportional to the pressure: If the pressure increases, the volume decreases. If the pressure decreases, the volume increases.
As the volume of the container increases, the pressure decreases because the molecules collide less against the wall of it.
