Answer:
c because isomers are compounds with the same molecular formula but different structural formula.
The solution would be like
this for this specific problem:
<span>1.0
</span>atm + 2.0 atm
+ 3.0 atm = 6.0 atm
So the partial pressure of
the helium 3.0 atm.
<span>I hope this helps and if you
have any further questions, please don’t hesitate to ask again.</span>
Answer:
C
Explanation:
water has the highest specific heat capacity of any liquid,as a hydrogen bond
Elements of Group 1 and group 2 in the periodic
table contain elements so reactive that they are never found in the free state
<u>Explanation</u>:
The metals in group 1 of periodic table consisting of 'alkali metals' which include lithium, potassium, sodium, rubidium, Francium and caesium. They are highly reactive because they have low ionisation energy and larger radius. The group 2 metals consist of 'alkaline earth metals' which include calcium, strontium, barium, beryllium, radium and magnesium. These alkaline earth metal have +2 oxidation number, hence are highly reactive.
These both group metals are mostly reactive and so are never found in a free state. When they are exposed to air they would immediately react with oxygen. Hence, are stored in oils to avoid oxidation.
Answer:aluminum
Explanation:aluminum is a precious metal which means that it can be changed into a liquid solid or gas
