<h3>Answer:</h3>

              Ionic Bond

<h3>Explanation:</h3>

                     Types of Bonds can be predicted by calculating the difference in electronegativity.

If, Electronegativity difference is,

               Less than 0.4 then it is Non Polar Covalent  Bonding

               Between 0.4 and 1.7 then it is Polar Covalent  Bonding

               Greater than 1.7 then it is Ionic  Bonding

For Mg and Cl,

                   E.N of Chlorine             =   3.16

                   E.N of Magnesium        =   1.31

                                                             ________

                   E.N Difference                     1.85          (Ionic Bond)

<h3>Conclusion:</h3>

                   MgCl₂ being ionic in nature when dissolved in water dissociates into Magnesium and Chloride ions respectively.

C. How many grams of Na2SiO3 can react with 0.800 g of HF?
finlep [7]

Answer:

Mass = 0.610 g

Explanation:

Given data:

Mass of Na₂SiO₃ = ?

Mass of HF = 0.800 g

Solution:

Chemical equation:

Na₂SiO₃ + 8HF   →    H₂SiF₆ + 2NaF + 3H₂O

Number of moles of HF:

Number of moles = mass/ molar mass

Number of moles = 0.800 g/ 20 g/mol

Number of moles = 0.04 mol

Now we will compare the moles of HF and Na₂SiO₃.

           HF        :        Na₂SiO₃

            8          :          1

            0.04    :       1//8×0.04 = 0.005

Mass of Na₂SiO₃:

Mass = number of moles × molar mass

Mass =   0.005 mol  × 122.07 g/mol  

Mass = 0.610 g

If the temperature of a gas is raised from 30°C to 60°C, what happens to the pressure?
Fofino [41]
<h3>Answer:</h3>

The pressure increases by 10% of the original pressure

Thus the new pressure is 1.1 times the original pressure.

<h3>Explanation:</h3>

We are given;

  • Initial temperature as 30°C, but K = °C + 273.15
  • Thus, Initial temperature, T1 =303.15 K
  • Final temperature, T2 is 333.15 K

We are required to state what happens to the pressure;

  • We are going to base our arguments to Pressure law;
  • According to pressure law, the pressure of a gas and its temperature are directly proportional at a constant volume
  • That is; P α T
  • Therefore, at varying pressure and temperature

\frac{P1}{T1}=\frac{P2}{T2}

Assuming the initial pressure, P1 is P

Rearranging the formula;

[tex]P2=\frac{P1T2}{T1}[/tex]

P2=\frac{(P)(333.15K)}{303.15K}

     P2 = 1.099P

                 = 1.10 P

The new pressure becomes 1.10P

This means the pressure has increased by 10%

We can conclude that, the new pressure will be 1.1 times the original pressure.

Zigmanuir [339]
Since there are no choices given, my answer might not be what you're looking for. But it can definitely be a correct answer. The technique is called filtration. Filtration is a physical separation to separate the liquid and solid in a mixture. The mixture should be composed of an insoluble solid in a solvent. The mixture is usually passed through a semi-permeable barrier. In this case, a special piece of paper is used. The solvent is the liquid and the solid is the coffee bean grounds. Only the liquid can pass through the paper. The liquid that passes through the paper is generally called a filtrate.
