dezoksy [38]

Answer:

Neon

Explanation:

1s² 2s² 2p⁶ 3s¹ or [Ne] 3s¹

The outer most shell is the 3s¹.

For this atom to achieve stability, if it loses the electron in the 3s shell, it would resemble an inert element with a complete octet configuration. Therefore, the atom would be like:

1s² 2s² 2p⁶ which is the configuration of Ne

Carl's chemistry teacher asked him to make a 1 M sodium chloride solution. Carl measured 58.44 grams NaCl, added it to a volumet

Nastasia [14]

Answer:

After measuring the solute, Carl should first dissolve the solid in a small amount of DI water before diluting to the total volume.

Explanation:

To ensure that all the solute dissolves in the solution, first dissolve the solid in less than the total volume of solution needed.

Magnesium and nitrogen react in a combination reaction to produce magnesium nitride: 3 Mg N2 → Mg3N2 In a particular experiment,

vlada-n [284]

Answer:

The mass of Mg consumed is 21.42g

Explanation:

The reaction is

$3Mg+N_{2}-->Mg_{3}N_{2}$

As per balanced equation, three moles of Mg will react with one mole of nitrogen to give one mole of magnesium nitride.

as given that mass of nitrogen reacted = 8.33g

So moles of nitrogen reacted = $\frac{mass}{molarmass}=\frac{8.33}{28}=0.2975mol$

moles of Mg required = 3 X moles of nitrogen taken = 3X0.2975 = 0.8925mol

Mass of Mg required = moles X molar mass = 0.8925 X 24 = 21.42 g

Given the following equation and heat of reaction: 2 moles of A combine with 2 moles of B to produce 6 moles of C and 26 kJ What

Hoochie [10]

Answer: The change in enthalpy will be -13.

Explanation:-

Endothermic reactions are those in which heat is absorbed by the system and exothermic reactions are those in which heat is released by the system.

$\Delta H$ for Endothermic reaction is positive and $\Delta H$ for Exothermic reaction is negative.

$2A+2B\rightarrow 6C+26kJ$

$2A+2B\rightarrow 6C$ $\DeltaH=-26kJ$

When 1 mole of A combining with 1 mole of B to produce 3 moles of C

Thus as the stoichiometry has got half of the original , enthalpy of the reaction will also get half.

Thus for reaction :

$A+B\rightarrow 3C+\frac{26}{2}kJ$

$A+B\rightarrow 3C$ $\DeltaH=-13kJ$

Thus the change in enthalpy will be -13.
