A neutral isotope has 49 neutrons and 36 electrons. Identify the element symbol of this isotope and determine the mass number an

Marta_Voda [28]

Explanation:

In an atom , the relation between the subatomic particles of the atom are given as follows -

For a neutral atom ,

Atomic number = number of protons = number of electrons ,

Mass number = number of protons + number of neutrons,

Hence , from the given information of the question,

number of neutrons = 49 ,

number of electrons = 36 ,

Hence , by using the above relation,

Atomic number = 36

number of protons = 36

Since ,

Mass number = number of protons + number of neutrons

Mass number = 36 + 49 = 85 .

By taking the help of periodic table , as atomic number = 36 ,

The elements is Krypton ( Kr )

Kr ⁸⁵₃₆

What is the standard entropy change for the reaction below? 2 CO(g) + 2 NO(g) → N2(g) + 2 CO2(g) S o (CO(g)) = 197.7 J/(mol·K) S

photoshop1234 [79]

Answer:

$\Delta _RS^o=-230J/(mol*K)$

Explanation:

Hello,

In this case, for the given chemical reaction:

$2 CO(g) + 2 NO(g) \rightarrow N_2(g) + 2 CO_2(g)$

The standard entropy change is computed by subtracting the products standard enthalpy and the reactants standard enthalpy considering each species stoichiometric coefficients:

$\Delta _RS^o=S ^o_{N2(g)}+2S ^o_{CO2(g)}-2S ^o_{CO(g)}-2S ^o_{NO(g)}\\\\\Delta _RS^o=191.6J/(mol*K)+2*213.8J/(mol*K) -2*213.8J/(mol*K) -2*210.8J/(mol*K)\\\\\Delta _RS^o=-230J/(mol*K)$

Best regards.

Which type of landforms forms at the plate boundary as a result of this stress<br>

stealth61 [152]

Answer:

Landform: MID-OCEAN RIDGE Plate Boundary: DIVERGENT Type of Plates: 2 Oceanic Plates (OP) pull apart How is it formed? Two oceanic plates (OP) move away from each other, allowing magma to rise up from inside the Earth. The magma reaches the bottom of the ocean, turns in to lava and cools (forming new rock)
