Idk if this is the information you need but the energy level gets higher the farther you move down the Periodic Table. Every element in a vertical line has the same energy level.

A breeder nuclear reactor is a reactor in which nonfissile U-238 is converted into fissile Pu-239. The process involves bombardm
VARVARA [1.3K]

<u>Answer:</u> The nuclear equations for the given process is written below.

<u>Explanation:</u>

The chemical equation for the bombardment of neutron to U-238 isotope follows:

_{92}^{238}\textrm{U}+n\rightarrow _{92}^{239}\textrm{U}

Beta decay is defined as the process in which neutrons get converted into an electron and a proton. The released electron is known as the beta particle.

_Z^A\textrm{X}\rightarrow _{Z+1}^A\textrm{Y}+_{-1}^0\beta

The chemical equation for the first beta decay process of _{92}^{239}\textrm{U} follows:

_{92}^{239}\textrm{U}\rightarrow _{93}^{239}\textrm{Np}+_{-1}^0\beta

The chemical equation for the second beta decay process of _{93}^{239}\textrm{Np} follows:

_{93}^{239}\textrm{Np}\rightarrow _{94}^{239}\textrm{Pu}+_{-1}^0\beta

Hence, the nuclear equations for the given process is written above.

Consider a balloon of nitrogen gas and a crystal of sugar sitting on a table at room conditions. Select the appropriate statemen
yKpoI14uk [10]

Answer:

about the same

Explanation:

Thermal energy is constant at a certain temperature in general. The energy is denoted by K_BT

Where,

K_B is the Boltzmann constant

T is the absolute temperature

Given that the balloon filled with nitrogen gas and the crystal of sugar are at room conditions means that they have same conditions and thus they will possess same energy irrespective of the states of the matter.

Thus,

The thermal energy of the sugar molecules is <u>about the same</u> as that of nitrogen molecules.

Why is the Pacific Northwest receives so much precipitation?
lyudmila [28]

The Cascades rain shadow can be described as such: ocean-influenced moist air masses are forced to rise when they meet the tall moun- tains. The rising air cools, condenses, and the moisture falls as precipitation. On the leeward (dry) side of the mountain, the now dry air warms and sinks.

When 0.313 g of Mg is heated strongly in a nitrogen (N2) atmosphere, a chemical reaction occurs. The product of the reaction wei
borishaifa [10]

Answer:

Mg₃N₂ (magnesium nitride)

Explanation:

M(total) = M(mg) + M (n)

M (n) = M(total) -  M(mg)

        = 0.433g - 0.313g

        = 0.12g

mole (N) =  0.12g / 14.0067 g/mol

              = 0.008567

mole Mg = 0.313g / 24.3050 g/mol

              = 0.012878

Mg = 0.012878 / 0.008567

     = 1.5

N = 0.008567 / 0.008567

   = 1

multiply by 2 to get whole numbers

Mg = 1.5 × 2 = 3

N = 1  × 2 = 2

Mg₃N₂ (magnesium nitride)
