Answer:
4.25*10^18
Explanation:
1 mole =6.023*10^23 particles
so 7.07*10^-6 mole=6.023*10^23*7.07*10^-6 particles=4.25*10^18 particles
You were supposed to attach a picture so I know what the question id
Answer:
A.
Explanation:
We know quite well that there are three states of matter. Solid,liquid and gaseous states.
While the gaseous states gives the highest freedom of movement, the solid state gives the least freedom of movement. Molecules and atoms of a solid are so tightly packed.
This makes them very dense as they are held together by strong intermolecular forces of attraction. These strong forces prevents the movement of the particles.
As these particles are strongly attracted towards each other, they tend to be incompressible.
Answer:
Explanation:
From the given information:
Let y(t) be the amount of sugar in tank A at any time.
Then, the rate of change of sugar in the tank is given by:

The rate of the sugar coming into the tank is 0


Initial amount of sugar = 25 Pounds
Now; y(0) = 25
25 = Ce⁰
C = 25
So; y(t) = 25 
Thus, the amount of sugar at any time t = 
B) For tank B :

Hi what do you mean by this? i dont understand at all pls explain :)
