Answer:
moles H = 2 x 0.0649=0.130
ions = 0.130 x 6.02 x 10^23=7.81 x 10^22
Explanation:
When solid aluminum metal is reacted with diatomic chlorine gas, solid aluminum chloride is formed. This reaction is an example of synthesis or chemical combination in which two elements, aluminum and chlorine combine to form a new compound aluminum chloride.
Word equation: Aluminum (s)+ Chlorine (g)---> Aluminum chloride(s)
Molecular formula of the product formed is .
Therefore the balanced chemical equation representing the reaction of solid aluminum with gaseous dichlorine can be represented as,
Answer:
0.02 mol
Explanation:
Given data:
Number of moles of nitrogen = ?
Volume of sample = 400 cm³
Pressure = 790 mmHg
Temperature = 27°C
Solution:
Volume of sample = 400 cm³ (400/1000=0.4 L)
Pressure = 790 mmHg (790/760 = 1.04 atm)
Temperature = 27°C (27+273=300 K)
The given problem will be solve by using general gas equation,
PV = nRT
P= Pressure
V = volume
n = number of moles
R = general gas constant = 0.0821 atm.L/ mol.K
T = temperature in kelvin
1.04 atm ×0.4 L = n× 0.0821 atm.L/ mol.K ×300 K
0.416 atm.L = n× 24.63 atm.L/ mol
n = 0.416 atm.L /24.63 atm.L/ mol
n = 0.02 mol
Carbon has a tendency to form covalent bonds.
If it's an endothermic reaction, then that means heat is being added to the system therefore H>0. Entropy is disorder, and since there are more moles on the products side, entropy is increasing therefore S>0 as well.
