Q = mCpΔT

Cp = 2.22 J/g°C
m = 150 g
ΔT = T(final) - T(initial) = -15°C - (-30°C) = +15°C

q = (150 g)(2.22 J/g°C)(15°C) = 4,995 J

What nuclide undergoes fission to form molybdenum-103, atomic number 42, tin-131, atomic number 50, and two neutrons?
FrozenT [24]

Answer:

The correct answer is Pu, 234.

Explanation:

In the given case, let us consider the reactant as X. Now the mass number (balanced) on both the sides will be,

Mass of X = Mass of Molybdenum + Mass of Tin + Mass of neutrons

M = 1 * 103 + 1 * 131 + 2 * 0

M = 234

Now the atomic number (balanced) on both the sides,

Atomic number of X = Atomic number of Molybdenum + Atomic number of Tin + Atomic number of neutrons

A = 1*42 + 1*50 + 2*1

A = 94

The atomic number 94 is for the element Plutonium, whose symbol is Pu. Thus, the reactant is 234-Pu.

Which agent would most likely
fredd [130]

Answer:

Wind

Explanation:

Most conifers and about 12% of the world's flowering plants are wind-pollinated. Wind pollinated plants include grasses and their cultivated cousins, the cereal crops, many trees, the infamous allergenic ragweeds, and others. All release billions of pollen grains into the air so that a lucky few will hit their targets.

As the temperature of a liquid solvent increases, the amount of solute that can dissolve in it ________. decreases remains const
Nookie1986 [14]
Answer:
              
<span>As the temperature of a liquid solvent increases, the amount of solute that can dissolve in it <u>increases</u>.

Explanation:
                    The solubility of most solutes in a solvent increases with increase in temperature. This solubility is closely related to the heat of solution, (the heat evolved or absorbed when solute is dissolved in solvent). Hence, majority of solutes when dissolved in solvent absorbs heat and makes the overall heat of solution positive. Hence, in this case more heat provided will increase the rate of solubility.</span>
