Hydrogen has 1 valence electron because it's in the first family. Since it only has one valence electron it can fit on the first shell
Answer:
a) mass flow = 56940 Kg/h
b) mass flow = 202.5 mol/s
Explanation:
∴ δ C6H6 = 876 Kg/m³,,,,,wwwcarlroth.com
⇒ 65m³/h * 876 Kg/m³ = 56940 Kg/h
⇒ 56940 Kg/h * ( 1000 g/Kg ) * ( mol/ 78.11 g) * ( h/3600s )= 202.5 mol/s
Answer:
The decomposition of ethane is 153.344 times much faster at 625°C than at 525°C.
Explanation:
According to the Arrhenius equation,
where,
= rate of reaction at
= rate of reaction at
= activation energy of the reaction
R = gas constant = 8.314 J/K mol
The decomposition of ethane is 153.344 times much faster at 625°C than at 525°C.
Best Answer:<span> </span><span>Sorry its kind of hard to explain, you just need to study hesslaw, practice makes perfect, keep studying!
A. REACTION 2 IS MULTIPLIED BY 3 (HESS LAW)
ΔH2= -6129 j
B. IF REACTION IS REVERSED YOU FLIP THE SIGN OF ΔH
ΔH = 92.3 kJ
C. KIND OF HARD TO EXPLAIN, BUT I CAN TRY AND SHOW YOU
EQUATION 1 (FLIP) CH4 --> C + H2
EQUATION 4 (FLIP AND MULTIPLY BY 2) H2O(g) --> H2O(l)
ΔH = -890.7</span>
2NaCl + Br2
This is because Na (Sodium) still needs to retain the coefficient or amount of two. Since Chlorine already has 2 on the reactants side, having a two in front would make sense so both elements can have a two.
Bromine would have the subscript of two as in the reactants side of the equation, it is also under the coefficient of two. Thus, it would need to carry it to the products side in order to keep the equation balanced.
Hope this helps!
