Given volume of hydrogen = 25 L
Standard temperature = 273 K
Standard pressure = 1 atm
R is gas constant = 0.08206 L.atm/(mol.K)
Plugging in the values in ideal gas equation and solving for moles of hydrogen (n):
n = 1.12 mol
Answer:
Changing two or more variables makes it difficult to find a cause and effect relationship.
Answer : The specific heat of tungsten is,
Explanation :
In this problem we assumed that heat given by the hot body is equal to the heat taken by the cold body.
where,
= specific heat of tungsten = ?
= specific heat of water =
= mass of tungsten = 19.5 g
= mass of water = 78.5 g
= final temperature =
= initial temperature of tungsten =
= initial temperature of water =
Now put all the given values in the above formula, we get
Therefore, the specific heat of tungsten is,
In chemistry, the octet rule explains how atoms of different elements combine to form molecules. In a chemical formula, the octet rule strongly governs the number of atoms for each element in a molecule; for example, calcium fluoride is CaF2 because two fluorine atoms and one calcium satisfy the rule. Hope this helps
