Answer:
The new pressure will be 0.225 kPa.
Explanation:
Applying combined gas law:

where,
are initial pressure and volume at initial temperature
.
are final pressure and volume at initial temperature
.
We are given:



Putting values in above equation, we get:


Hence, the new pressure will be 0.225 kPa.
Answer:
a. similar properties
Explanation:
In a given column of the periodic table, the elements have similar properties.
A column on the periodic table is known as a group or family. The group is a vertical arrangement of elements on the periodic table.
Elements in the same group have the same number of valence electrons after their group number.
For example, all the elements in group 1 have one valence electron. Those in group 2 have 2 valence electrons.
The valence electrons of an atom determines its chemical properties. So, all elements in the same group have the same chemical properties.
Answer:
C
Explanation:
The non metal in HCl is Chlorine and the name of the acid is Hydrochloric acid.
H = hydro
Cl = chloric
So I imagine this new acid, yet to be discovered even by the crew of the Star Ship enterprise, would be
HydroBlobbic acid
I await news from Spock on how things are going on the discovery of such a thing. So far he has not said anything about it.
1 L ---------- 1000 mL
274 L ------- ??
274 x 1000 / 1 => 2,740 mL
hope this helps!
