Answer:
Explanation:
Hello there!
In this case, according to the given chemical reaction, we can set up the heat of reaction per mole of gasoline as shown below:
Now, since the total heat is obtained by multiplying the moles and heat of reaction, we can calculate the moles as shown below:
Finally, since the molar mass of gasoline is 114.22 g/mol, we can easily calculate the mass as follows:
Best regards!
I’m stuck on that question
A displacement reaction will occur from the system given above. The chlorine molecules will displace the bromide ions in the solution of sodium bromide. The reaction will yield to sodium chloride and bromine. The reaction will be:
2NaBr + Cl2 = 2NaCl + Br2
Answer:
It is important to know if a resource is renewable or non-renewable because renewable resources are self-sustaining (unlike non-renewable resources). If a non-renewable resource is used too often, that resource may eventually become non-existant. This can also happen to renewable resources, but it is more difficult.
Use the formula in terms of half life from the normal exponential functions
<span>
N(t) = N(0) (1/2) ^ (t/thalf) </span>
<span>
N(0) is the original quantity </span>
<span>
N(t) = quantity remaining at time t </span>
<span>
t is the time </span>
<span>
thalf is half life </span>
<span>
1/16 = (1/2)^(t/3.82) </span>
<span>
16 = 2^(t/3.82) </span>
<span>
4 = t/3.82 </span>
<span>
t = 15.28 days
