Group 1A element sodium combines with Group 7A element chlorine to form sodium chloride or table salt. Based on this information
Ymorist [56]
The answer is Na < Cl

Chlorine is more electronegative than sodium because this follows the trend of the periodic table. The trend states that an element's electronegativity increases from left to right of a period and bottom to up of a group. Since sodium and chlorine are from the same period, and chlorine is at the right of sodium, chlorine is more electronegative.

Convert the following pressures to pressure in standard atmosphere 151.98 kPa 456 torr
Korolek [52]

Answer:

Kpa to atm = 1.5 atm

torr to atm = 0.6 atm

Explanation:

Atmospheric pressure:

It is the pressure exerted by atmosphere at a sea level with the means value of 101.325 pascal.

It is also known as barometric pressure.

It is denoted as "atm"

The value of standard atmospheric pressure is 1.

Kpa to atm:

To convert the kilopascal into atm we would divide the given value by 101.

151.98 kpa × 1 atm /101.325 kpa

1.5 atm

torr to atm:

To convert the torr into atm we would divide the given value by 760.

456 torr  × 1 atm /760 torr

0.6 atm
