Answer:
water is made of 2 hydrogen atoms bonded by 1 oxygen atom
Explanation:
Answer:
81.54 °C
Explanation:
Use the equation
q = mcΔT
348 = 20.9(0.902)(100-t)
t = 81.54 °C
*note, you don't have to convert these to kelvin since the difference will be the same
Answer:
answer is 34.996 or 35 grams
Explanation:
Br2 + AlCl3
mass 34.996 29.2
RFM 160 133.5
moles 0.2187 0.2187
Answer:
Option-B (k) is the correct answer.
Explanation:
As we know the rate of reaction is given as;
Rate = k [A]ˣ
Where;
Rate = Rate of Reaction
k = rate constant
[ ] = concentration of A
x = order of reaction
So, from this equation we found that rate of reaction depends upon concentration and rate constant (k).
Now,
The rate constant is as follow,,
k = Ae^(Ea/RT)
This equation is known as Arrhenius Equation, according to this equation rate constant depends upon Temperature and Activation energy. Greater the temperature greater is the rate constant and hence greater is the rate of reaction. Or smaller the activation energy greater is the rate constant and vice versa.
