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

Answer:
1.08 M
Explanation:
From the question given above, the following data were obtained:
Initial volume (V₁) = 45 mL
Initial concentration (C₁) = 6 M
Final volume (V₂) = 250 mL
Final concentration (C₂) =?
The final concentration of the solution can be obtained by using the dilution formula as illustrated below:
C₁V₁ = C₂V₂
6 × 45 = C₂ × 250
270 = C₂ × 250
Divide both side by 250
C₂ = 270 / 250
C₂ = 1.08 M
Therefore, the final concentration of the solution is 1.08 M.
Answer:
Answer. Explanation: Chlorine gas bleaches the damp litmus (red or blue). Bleaching is an oxidation process.
Copper has 29 protons in the nucleus, while Nickel has 28 protons.
