How many grams of MgCl2 will be obtained when 435 mL of 0.300 M HCl react with an excess of Mg(OH)2?
Marina CMI [18]
The grams of Mg(OH)2 produced is calculated as below

calculate the moles of HCl produced =molarity  xvolume/1000

= 0.3 x 435/1000= 0.1305 moles

write the equation for reaction
Mg(OH)2 +2HCl = MgCl2 + 2H2O

by use of mole ratio between HCl :MgCl2  which is 2 :1  the  moles of HCl =  0.1305 x1/2 =0.0653  moles of MgCl2

mass of MgCl2 = moles x molar mass

= 0.0653mol x95 g/mol = 6.204  grams of MgCl2

1718 l of a 0.3556-m c3h7oh solution is diluted to a concentration of 0.1222 m, what is the volume of the resulting solution
Agata [3.3K]
Answer : The volume of the resulting solution will be 0.4999 L.

Explanation : As the two molar concentration of the C_{3} H_{7}OH solution are given and one of the volume concentration needs to be found.

So, according to the formula :-  m_{1}V_{1} = m_{2}V_{2}

And here if we consider V_{1} as 0.1718 L moles and m_{1}  as 0.3556 moles then we need to find V_{2} as m_{2}  is given as 0.1222 moles.
Hence on solving the formula we get,  

 V_{2} = (0.1718 X 0.3556) / 0.1222 = 0.4999 L

Metals (M) in group 2 of the periodic table form ionic bonds
egoroff_w [7]

Answer:

16

Explanation:

Group two elements are alkaline earth metal.

All these have two valance electrons. In order to achieve noble gas configuration it loses its two valance and get complete octet.

Reaction with group 16.

Reaction with oxygen,

They react with oxygen and form oxide.

2Ba   +   O₂   →    2BaO

2Mg  +   O₂   →    2MgO

2Ca +   O₂   →    2CaO

this oxide form hydroxide when react with water,

BaO  + H₂O   →  Ba(OH)₂

MgO  + H₂O   →  Mg(OH)₂

CaO  + H₂O   →  Ca(OH)₂

With sulfur,

Mg + S   →  MgS

Ca + S   →  CaS

Ba + S   →  BaS
