1 mol ----------- 6.02 x 10²³ atoms Na
( mols Na) ------ 9.8 x 10²³ atoms Na
( mols Na ) = ( 9.8 x 10²³ ) x 1 / 6.02 x 10²³
( mols Na) = 9.8 x 10²³ / 6.02 x 10²³
= 1.6 mols Na
hope this helps!
Answer:
900 K
Explanation:
Recall the ideal gas law:
Because only pressure and temperature is changing, we can rearrange the equation as follows:
The right-hand side stays constant. Therefore:
The can explodes at a pressure of 90 atm. The current temperature and pressure is 300 K and 30 atm, respectively.
Substitute and solve for <em>T</em>₂:
Hence, the temperature must be reach 900 K.

Answer:
CuCl2 + 2NaNO3 - > Cu(NO3)2 + 2NaCl
The given thermochemical reaction is between hydrogen gas and chlorine gas to form hydrogen chloride.
This can be represented as:
Δ=-184.6 kJ/mol
So when two moles of HCl is formed, 184.6 kJ of energy is released.
Calculating the heat released when 3.18 mol HCl (g) is formed in the reaction:
Therefore, 293.5 kJ of heat is released when 3.18 mol HCl is formed in the reaction between hydrogen and chlorine.
