Water has a definite volume but not a definite shape making the correct answer A.
Answer:
3.42×10²¹ of particles
Explanation:
To determine the number of particles we should know, that:
1 mol of anything contains 6.02×10²³ particles
Therefore we have to find out, how many moles corresponds to 0.332 g of NaCl.
The conversion is: 0.332 g / 58.44 g/mol = 0.00568 moles
The rule of three to determine the number of particles is:
1 mol of NaCl has 6.02×10²³ particles
0.00568 moles must have (0.00568 . 6.02×10²³ particles )/1 = 3.42×10²¹
What force causes
venus to travel along a curved path instead of moving in a straight line
The force that causes
Venus to travel along a curved path instead of moving in a straight line is the
gravitational force between the Sun and the Venus. The more massive a body is,
the more it attracts bodies near it.
Answer:
No
Explanation:
it will not be a irreversible change because u can give back the pen if it is in its original state and the shop keeper might accept it back that is what mostly happens. if the pen breaks or is used then it might me called a irreversible change until then it is reversible if not used yet.
