Answer:
a rection will most likely occur if the colliding partilces have the proper orientation and energy. The reactions occur becasue the molecules collide. But not all the collisions result in a reaction. The collisions have to meet some requirements

5. A
Answer:
2
Explanation:
In balancing nuclear reactions the mass number and atomic numbers are usually conserved. This implies that from the given equation, the sum of the number of the subscript on the right hand side must be equal to that on the left hand side. This also applies to the superscript:
For the mass numbers(superscript):
235 + 1 = 1 + 139 + 95
236 = 235
This is not balanced
For the atomic number:
92 + 0 = 0 + 53 + 39
92 = 92
This is balanced.
We simply inspect to see how to balance the mass number.
By putting a coefficient of 2 behind the neutron atom, the equation becomes balanced.
Answer : The maximum mass of aspartame is, 5142.3 grams
Explanation : Given,
Molal-freezing-point-depression constant for water =
Mass of water (solvent) = 2.50 kg
Molar mass of aspartame = 294.3 g/mole
Formula used :
where,
= change in freezing point
= freezing point of solution =
= freezing point of water =
i = Van't Hoff factor = 1 (for non-electrolyte)
= freezing point constant for water =
m = molality
Now put all the given values in this formula, we get
Therefore, the maximum mass of aspartame is, 5142.3 grams
