<em>Answer:</em>
- Such a alkane has only one ring that is cyclooctane.
<em>Explanation:</em>
- The general formula of alkane is CnH2n+2. Such general formula is applicable for only open chain alkane.
- When alkane form ring, then this formula does not remain valid.
- The general formula of Cycloalkane is CnH2n.
As in this case, there are 8-carbon and 16-hydrogen that is according to above cycloalkane formula.
Answer : The enthalpy change for dissolving this salt on a energy per mass basis is 132.4 J/g
Explanation :
Heat released by the reaction = Heat absorbed by the calorimeter + Heat absorbed by the water
where,
q = heat released by the reaction
= heat absorbed by the calorimeter
= heat absorbed by the water
= specific heat of calorimeter =
= specific heat of water =
= mass of water =
= change in temperature =
Now put all the given values in the above formula, we get:
Now we have to calculate the enthalpy change for dissolving this salt on a energy per mass basis.
where,
= enthalpy change = ?
q = heat released = 331.08 J
m = mass of salt = 2.50 g
Therefore, the enthalpy change for dissolving this salt on a energy per mass basis is 132.4 J/g
The seasons are caused by the tilt of the Earth on its axis is the correct answer.
Summer starts based off each countries calendar so that can't be right. And during Summer days are longer because we have more sunlight so that one isn't right. And as the earth revolves around the sun it stays in relatively the same distance away so that one is incorrect.
Hope this helps. (;
