Just try to find how you will get the reaction by adding the other reactions. Reverse the second eq as O is in reactant side and half it..
Now in the final reaction there is neither ozone nor oxygen so now you have oxygen on the products side after adding reversed
2 and 3, O ->1/2 O2
adding this to the third eq you get,
NO+O +O3 -> NO2 +3/2 O2
Now you need to remove O3 and O2 using the first equation,
So reverse the first one,half it and add, 3/2O2-> O3 adding it removes O3 and O2 you get the requires equation,
NO + O->NO2 you can do the calculation bit yourself when you add reactions Enthalpy is also added by Hess law so yeah that part should be pretty simple.
Answer:
333.3mL
Explanation:
Using the formula as follows:
C1V1 = C2V2
Where;
C1 = initial concentration (M)
C2 = final concentration (M)
V1 = initial volume (mL)
V2 = final volume (mL)
According to the information provided in this question,
C1 = 4.00M
C2 = 1.50M
V1 = 125mL
V2 = ?
Using C1V1 = C2V2
4 × 125 = 1.5 × V2
500 = 1.5V2
V2 = 500/1.5
V2 = 333.3mL
Therefore, the CuSO4 solution needs to be diluted to 333.3mL to make 1.50 M solution.
Answer:
Malleability is intensive
Length is extensive
Hardness is intensive
Volume is extensive
Explanation:
Extensive properties change when u change the size of an object and intensive properties don’t
Also I just took the quiz
The answer is: single replacement.
Single replacement is reaction where neutral element metal or nonmetal become an ion as it replaces another ion in a compound.
In this balanced chemical reaction magnesium (Mg) replaces copper (Cu).
Magnesium changes oxidation number from 0 to +2 (oxidation) and copper changes oxidation number from +2 to 0 (reduction).
Reactivity series is an empirical progression of a series of metals, arranged by their reactivity from highest to lowest (alkaline metals have highest reactivity and Noble metals lowest reactivity):
K > Ba > Sr > Na > Ca > Mg > Be > Al > Mn > Zn > Cr> Fe > Cd > Co > Ni > Sn > Pb > H(in acids) > Cu > Hg > Ag.
Metal higher in the reactivity series will displace another and it will be oxidized.
Answer:
Approximately .
Explanation:
Make use of the molar mass data () to calculate the number of moles of molecules in that of :
.
Make sure that the equation for this reaction is balanced.
Coefficient of in this equation: .
Coefficient of in this equation: .
In other words, for every two moles of that this reaction consumes, two moles of would be produced.
Equivalently, for every mole of that this reaction consumes, one mole of would be produced.
Hence the ratio: .
Apply this ratio to find the number of moles of that this reaction would have produced:
.
