Answer:
The new volume is 7,606.96 Liter.
Explanation:
The combined gas equation is,
where,
= initial pressure of gas in the balloon = 0.918 atm
= final pressure of gas in the balloon = 0.0012 atm
= initial volume of gas in the balloon = 
= final volume of gas in the balloon = ?
= initial temperature of gas in the balloon = 
= final temperature of gas in the balloon = 
Now put all the given values in the above equation, we get:
The new volume is 7,606.96 Liter.
Answer:
( B) They all have their valence electrons in the same type of subshell.
Explanation:
With each period, a new shell is added to the atom.
Further, the groups are classified based on the type of subshell the last electron enters and number of valence electrons.
For all elements of same group, the last electron enters the same type of subshell.
Say, for group 1, last electron enters s orbital and they have 1 valence elctron.
for group 17, last electron enters p orbital and they have 7 valence electrons.
(A) and (D) are wrong because, energy level of the valence electrons is determined by the principle quantum number n and l and not by the type of subshell(only l) they enter.
(C) if the valence electron enters p orbital, then the elements will be placed in the p- block.
=The measure of warm and coldness of an object or substances with references to some standard value is known as temperature.
= We measure temperature by Fahrenheit (°F) scale, the Kelvin (K), and the Celsius (°C).
