Answer:
cccfffffff
Explanation:
Integrated rate law for second order kinetics is:
Where, is the final initial concentration
is the initial concentration = 0.355 M
k is the rate constant = 0.540 (Ms)⁻¹
t is the time = 15.9 seconds
Applying the values in the above expression as:-
<u>11.4 M of will be left after 15.9 seconds have passed.</u>
Answer: Your friend is incorrect.
Explanation: If we have an object or something that isn’t moving, (let’s say a notebook on a desk). If there is change, and the notebook moves, there is acceleration. Force = Mass times acceleration, f = m*a. There has to be a force, first of all. If you touched the notebook and moved it, some of your energy is transferred and now the notebook has kinetic energy. If our system is you and the notebook, the total energy doesn’t change. the energy is transferred, but doesn’t change. Your friend is not correct. Please give brainliest hope this helped!
Answer:-
500324 grams
Explanation:-
Heat absorbed Q = M x Cp x T
We are given T = 10 [ The maximum allowed temperature increase]
Plugging in the values
6.70 x 10^ 6 J = M x 30.8 J / (K mol) x 10 K
M = 6.70 x 10 ^6 / (30.8 x 10)
= 21753 moles
Atomic Mass of sodium =23 gram / mol
Grams of liquid sodium required = 21753 moles x 23 grams / mol
= 500324 grams
