Under most conditions, an atom has the same number of protons and electrons.
Zepler [3.9K]

Answer:

True! Under most conditions, they are usually the same.

This is because to balance out the negativity or positivity of an atom, the opposite joins in.

Hope this helps.

What is the barometric pressure exerted in pascals (Pa) of a column of decane (density = 0.7300 g/cm3) 636.2 mm in height?
BartSMP [9]
<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
