Answer:
it will change
Explanation:
if temperature of room is hot it doesn't freeze.
if temperature of room is cold it freezes
We have been given the OH⁻ ion concentration, we can calculate the pOH concentration.
pOH = -log [OH⁻]
pOH = - log (5.5 x 10⁻⁵ M)
pOH = 4.26
we can then calculate the pH value
pH + pOH = 14
pH = 14 - 4.26
pH = 9.74
since pH > 7 the solution is basic.
by knowing the pH value, we can calculate the H₃O⁺ concentration
pH = - log[H₃O⁺]
[H₃O⁺] = antilog (-pH) = antilog (-9.74)
[H₃O⁺] = 1.82 x 10⁻¹⁰ M
So 6.02*10^22 is avogadro constant, which is the amount of atoms in one mole. If you look Xenon up in the periodic table you will find it's mass given <span>131,293, which is grams per 1 mole.

Applying the conservation of mass:
Mass during bombardment:
242 (curium atom) + 4 (alpha particle)
= 246
This must equal the mass after bombardment:
1 (neutron) + x (unknown product)
246 = 1 + x
x = 245
The product is Californium-245
When the concentration of all the reactants increases, more molecules or ions interact to form new compounds, and the rate of reaction increases. When the concentration of a reactant decreases, there are fewer of that molecule or ion present, and the rate of reaction decreases.
