Answer:
Molecules must collide with sufficient energy, known as the activation energy, so that chemical bonds can break. Molecules must collide with the proper orientation. A collision that meets these two criteria, and that results in a chemical reaction, is known as a successful collision or an effective collision.
Mass of a sample = M = ?
Density of a sample = D = 8.9 g/cm³
Volume of the sample = 6 cm³
By using the formula = D = M / V
Density = Mass / Volume
Mass = Density x Volume
M = D x V
Putting the values of density and mass of the sample
M =8.9g/cm³ x 6cm³ =53.4 g
<span>So, the mass of the material in grams is 53.4g</span>
Answer: The new concentration of the solution is 0.143 M.
Explanation:
Given: 
= 300.0 mL, 
= 0.335 M
= 700.0 mL, 
= ?
Formula used is as follows.
Substitute values into the above formula as follows.
Thus, we can conclude that the new concentration of the solution is 0.143 M.
C6H6 is benzene, an organic compound. I would imagine it would be immiscible, since most organic compounds don’t dissolve in water very well.
