Answer:
The answer to your question is number 2. NaNO₃ + H₂O
Explanation:
The reaction that is represented in this problem is an acid-base reaction. An acid-base reaction is a double displacement reaction.
The cation of a reactant attaches to the anion of the other reactant and viceversa.
Reactants NaOH and HNO₃
Cations Na⁺ H⁺
Anions OH⁻ NO₃⁻
Following the previous rule
Products NaNO₃ + H₂O
The products are a salt and water.
Answer:
True.
Explanation:
Hello,
Catalysis states that a catalyst is consumed but subsequently regenerated via inner mechanisms that allows it to achieve it. Besides, it is true that the inner mechanism has a lower activation energy which allows the reaction to be rapidly carried out in comparison with the catalystless chemical reaction.
Best regards.
Answer:
Part A: 27.8 L; Part B: 0.500 mol
Explanation:
Part A
For an ideal gas, we can use the equation:
PV = nRT, where P is the pressure, V is the volume, n is the number of moles, R is the gas constant, and T is the temperature.
In the beggining:
P*48.0 = 1.90*RT
P/RT = 1.90/48.0
P/RT = 0.03958
For constants pressure and temperature, after 0.800 mol of gas leaks out: n = 1.90 - 0.800 = 1.10 mol
PV = 1.10*R*T
P/RT = 1.10/V
0.03958 = 1.10/V
V = 1.10/0.03958
V = 27.8 L
Part B
In the beginning
PV = nRT
P*70.0 = 2.00*RT
P/RT = 2.00/70.0
P/RT = 0.02857
After the gas leaked out:
PV = nRT
P*17.5 = nRT
P/RT = n/17.5
0.02857 = n/17.5
n = 0.500 mol
Answer:
Condensed equation:
Complete ionic equation :
Net ionic equation :
Explanation:
A double displacement reaction is one in which exchange of ions take place. The salts which are soluble in water are designated by symbol (aq) and those which are insoluble in water and remain in solid form are represented by (s) after their chemical formulas.
The balanced chemical equation is:
Condensed equation :
Complete ionic equation : In complete ionic equation, all the substance that are strong electrolyte and present in an aqueous are represented in the form of ions.
Net ionic equation : In the net ionic equations, we are not include the spectator ions in the equations. Spectator ions are the ions present on reactant and product side which do not participate in a reactions. The same ions present on both the sides.
