Answer:
12 moles of water will be produced
Explanation:
Given data:
Number of moles of NH₃ = 8.00 mol
Number of moles of O₂ = 14.0 mol
Number of moles of H₂O produced = ?
Solution:
Chemical equation:
4NH₃ + 7O₂ → 4NO₂ +6H₂O
Now we will compare the moles of reactant with product.
NH₃ : H₂O
4 : 6
8 : 6/4×8 = 12
O₂ : H₂O
7 : 6
14 : 6/7×14 = 12
12 moles of water will be produced.
Answer:
The correct answer will be " RbF > RbCl > RbBr > Rbl".
Explanation:
The size of the given ions will be:
<u>RbCl:</u>
⇒ 689kJ/mol
<u>RbBr:</u>
⇒ 660kJ/mol
<u>Rbl:</u>
⇒ 630kJ/mol
<u>RbF:</u>
⇒ 785kJ/mol
Now according to the size, the arrangement will be:
⇒ (785kJ/mol) > (689kJ/mol) > (660kJ/mol) >(630kJ/mol)
⇒ RbF > RbCl > RbBr > Rbl
The bond among all opposite charging ions seems to be strongest whenever the ions were indeed small.
The density of CO2 getting from experiment is 0.1/0.056 = 1.79 g/L. The percent error of this is (1.96 -1.79)/1.96*100%=8.67%. So the approximate percent error is 8.67%.
Given that the volume and amount of water are kept constant,
P/T = constant
P₁/T₁ = P₂/T₂
Normal atmospheric pressure is 746 mmHg and normal boiling point of water is 100 °C.
746/100 = 589/T₂
T₂ = 79.0 °C
