adoni [48]3 years ago
4 0
Arsenic's atomic number is 33.

Hence his electronic configuration is 1s^22s^22p^63s^23p hence his valence electrons are 4s^24p^3.

5 valence electrons

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.

➪ State the difference between molarity(M) and molality (m) ? <br><img src="https://tex.z-dn.net/?f=%5Csf%7B%7D" id="TexFormula1
lina2011 [118]
Molarity is the ratio of the moles of a solute to the total liters of a solution. The solution includes both the solute and the solvent. Molality, on the other hand, is the ratio of the moles of a solute to the kilograms of a solvent.

Naddika [18.5K]
<span>The flowers undergo photosynthesis so it is expected to release O2. When you zip the flower in a plastic bag and placed it in the refrigerator, the plastic bag will shrink in size. The extra air plus the O2 in the back forms gaseous water. This gaseous water will slowly liquefy and when placed in the fridge, it will condense to form water solids.</span>
