Chemistry

1) Assume M refers to a general element and Z referes to other general element.

2) Assume the chemical formula of the ionic compound is MₓZₐ

3) Then the dissociaton would be written:


MₓZₐ → XMᵃ⁺ + AZˣ⁻

That means that the ionic compoud will lead to the X cations Mᵃ⁺ whose oxidation state are a+, and A anions Zˣ⁻ whose oxidation state is x⁻.

5) For example: MgBr₂ (aq) → Mg⁺² (aq) + 2Br⁻ (aq)


6) Explanation: since the water molecules are polar, they will surround (solvate) the three ions that form the compound MgBr₂, overcoming the electrostatic forces that hold together the atoms in the ionic lattice.

Maurinko [17]
To find the weight of the gas you need to find the number of moles of using ideal gas formula. Remember to change the temperature unit to Kelvin and the pressure to kpa or atm

PV=nRT
n= PV/RT
n= 699 mmHg* 0.1333kpa * 0.357 L/   8.314 kpa*L  / mol*K  * (45 +273.15)K
n=<span>0.012 moles
</span>
weight= n * molecular weight
weght= 0.012 *92.448 g/mol= 1.109 grams

What volume would 4.5 moles of helium gas occupy at STP?
zzz [600]

Answer:

100.8 dm3

Explanation:

mol= volume      

       _______

       molar volume  

Simply transpose the formula      

volume=mol x molar volume  

           4.5molx22.4 mol/dm3

=   100.8dm3

NB  STP=22.4 dm3  or 22400 cm3

Darina [25.2K]

A indicator is a weak organic acid or a base which has shows different colors in acidic and basic mediums. The color change occurs when the weak acidic or basic indicator dissociates to give its respective conjugate base or conjugate acid.

Therefore the correct option would be Indicators are weak acids or bases.
