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.

If the pressure of a 2. 00 L sample of gas is 50. 0 kPa, what pressure does the gas exert if its volume is decreased to 20. 0 mL
N76 [4]

The equation used for the calculation is P subscript 1 V subscript 1 equals P subscript 2 V subscript 2. Thus, option B is correct.

The pressure of the gas with respect to volume is given with inverse proportion. The ideal gas equation is given as:

PV=nRT

<h3>Equation for relation between volume and pressure</h3>

The initial pressure of the gas has been given as, P_1=50\;\rm kPa

The initial volume of the gas has been, V_1=2\;\rm L

The final volume of the gas has been, V_2=0.02\;\rm L

The final pressure of the gas, P_2 is given as:

P_1V_1=P_2V_2\\\\P_2=\dfrac{P_1V_1}{V_2}

Thus, the equation used for the calculation is P subscript 1 V subscript 1 equals P subscript 2 V subscript 2. Thus, option B is correct.
