Neither. They are both 10 grams so they weigh the same.
The correct answer would be the second option. The outcome of a fusion reaction which involves isotopes of hydrogen would be the nuclei of the hydrogen isotopes join together to form a heavier element, and energy is released. A fusion reaction is a nuclear reaction which involves at least two nuclei or atoms combining forming products that are heavier than the reactants. Along with the formation of a new atomic nuclei, energy is released. Fusion of two isotopes of hydrogen, specifically deuterium and tritium, results to the formation of a neutron and a helium-3 atom atom. This reaction happens in the core of the Sun.
Explanation:
In real gases, there exists force of attraction between the molecules at low temperature and high pressure. This is because at low temperature there occurs a decrease in kinetic energy of gas molecules and high pressure causes the molecules to come closer to each other.
As a result, forces of attraction increases as molecules come closer to each other and therefore, gases deviate from an ideal gas behavior.
More is the polarity between the combining atoms in a compound more will be the presence of force of attraction between it. As a result, the molecules will not show ideal behavior.
As , HCl, and are all polar molecules therefore, these tend to deviate from ideal behavior.
Answer:
0.065M
Explanation:
The reaction expression is given as:
HCl + KOH → KCl + H₂O
Given parameters:
Volume of KOH = 25.81mL = 0.02581L
Molarity of KOH = 0.125M
Volume of HCl = 50mL = 0.05L
Unknown:
Molarity of the acid = ?
Solution:
To find the molarity of the acid, HCl, let us use the mole concept.
First, find the number of moles of the base, KOH;
Number of moles of KOH = molarity of KOH x volume of KOH
Number of moles of KOH = 0.125 x 0.0258 = 0.003225mol
From the balanced reaction equation:
1 mole of KOH reacted with 1 mole of HCl
0.003225mol of KOH will react with 0.003255mole of HCl
Molarity of HCl =
Molarity of HCl = = 0.065M
