The statement about the formation of the solar system that
are true and in a correct order are Gravitational force held the newly formed
planets around the sun; small planetary objects formed; hydrogen and helium
became concentrated in the outer solar system to form the outer planets. The answer
is letter D.
Answer: -
12.59
Explanation: -
Strength of NaOH = 0.0179 M
Volume of NaOH = 58.0 mL = 58.0/1000 = 0.058 L
Number of moles = 0.0179 M x 0.058 L
= 1.04 x 10⁻³ mol
Mol of [OH⁻] given by NaOH = 1.04 x 10⁻³ mol
Strength of Ba(OH)₂ = 0.0294 M
Volume of Ba(OH)₂ = 60.0 mL = 60.0/1000 = 0.060 L
Number of moles = 0.0294 M x 0.060 L
= 1.76 x 10⁻³ mol
Mol of [OH⁻] given by Ba(OH)₂ =2 x 1.76 x 10⁻³ mol
Total [OH⁻] = 1.04 x 10⁻³ mol + 2 x 1.76 x 10⁻³ mol
= 4.56 x 10⁻³ mol
Total volume of the mixture = 58.0 + 60.0
= 118.0 mL
118.0 mL of the solution has 4.56 x 10⁻³ mol [OH⁻]
1000 mL of the solution has 
= 0.0386 mol
Using the relation
pOH = - log [OH-]
= - log 0.0386
= 1.41
Using the relation
pH + pOH = 14
pH = 14 - 1.41
= 12.59

Explanation:
<h3>
Answer:</h3>
4551.37 Pascals
<h3>
Explanation:</h3>
The pressure refers to the force exerted by a substance per unit area.
The pressure is liquid is calculated by;
P = height × density × gravitational acceleration
In this case;
Height = 636.2 mm
Density = 0.7300 g/cm³
g = 9.8 N/kg
We need to convert mm to m and g/cm³ to kg/m³
Therefore;
Height = 636.2 mm ÷1000
= 0.6362 m
Density = 0.73 g/cm³ × 1000 kg/m³
= 730 kg/m³
Then, we can calculate the pressure;
Pressure = 0.6362 m × 730 kg/m³ × 9.8 N/kg
= 4551.3748 pascals
= 4551.37 Pascals
Therefore, the pressure of the column of decane is 4551.37 Pascals
B, mode since mode represents the data is the most frequent in the whole set, which in this case is 8cm
