Electron affinity is the change in energy of an atom with a neutral charge when an electron is added to form an anion. A more negative electron affinity corresponds to a greater attraction for an electron. Electron affinity become less negative down a group and from left to right in the periodic table.The correct answer would be the large nonmetal atoms. Large nonmetals have a higher electron affinity than metals, meaning they are more likely to gain electrons than atoms with a lower electron affinity.
Answer:
1,239,284pa
Explanation:
Assuming it's an ideal gas we use
PV=nRT
P=nRT/V
then we convert our Temperature into Kelvin
T=25+273.15 =298.12K
we convert our volume into M cubed
1.5L =0.0015 cubic meter
P=nRT/V
P= (0.75×298.12×8.314)/0.0015
P = 1,239,284pa

The climatology method of forecasting uses averages to predict future weather.
Answer: B
Explanation
The satellites and advanced technologies have helped meteorologists to forecast accurately.
There are four types of forecasting methods prevailing now.
They are climatology method, persistence method, analog method and trends method.
The persistence and trends method uses the previous day forecast and compare with today's condition to forecast about future.
The analog method is a complex method where the forecasting is done by comparing present weather condition with a similar condition occurred in the past to predict for future.
The climatology is the simplest method which uses average of weather conditions observed in the previous days to get accurate forecast for future.
