The new volume is mathematically given as
V2= 16.12 L
<h3>
What is the new volume?</h3>
Question Parameters:
A sample of gas has an initial volume of 20 L
and an initial pressure of 2.5 atm.
If the pressure changes to 3.1 atm
Generally, the equation for Pressure is mathematically given as
P1V1 = P2 V2
2.5 * 20 = 3.1 * V2
V2 = 50/3.1
V2= 16.12 L

atoms are made of 3 types of sub atomic particles- protons, neutrons and electrons
from these 3 particles, electrons are responsible for participating in chemical bonds. therefore chemical properties of elements are based on the number of electrons present.
valence electrons are the number of electrons in the outermost energy shell that are involved in chemical bonds.
atoms with same number of valence electrons are grouped in to columns called groups.
therefore elements of the same group have same number of valence electrons, hence similar chemical properties.
from the options given
only Be and Mg belong to the same group they both belong to group 2 with 2 valence electrons
therefore Be and Mg have similar chemical properties
answer is
1) Be and Mg
Answer:
closed circuit
Explanation:
Hope this helps- Good luck! ^w
Density= mass/volume
volume=mass/density
volume= 40.0g/1.114g per mL
volume= 35.90664273 mL
volume = 35.9 mL
