Answer:
A. m and n are independent from the molar coefficients of the reactants in the balanced chemical equation.
B. m and n must be determined by experiment.
Explanation:
rate = k[H2O2]^m × [I-]^n
The Order of Reaction refers to the power dependence of the rate on the concentration of each reactant.
Either the differential rate law or the integrated rate law can be used to determine the reaction order of reactants from experimental data.
Answer:
The Sun and the planets were born from a cloud of gas and dust called the solar nebula 4.6 billion years ago. The collapse of the solar nebula was most likely triggered by a shock wave from a nearby supernova explosion. The Sun formed in the center, with the planets surrounding it in a thin disk.
Explanation:
The specific heat capacity of unknown substance is 1.333 g/j/°c
<u><em> calculation</em></u>
Specific heat capacity is calculated using Q= MCΔT formula
where;
Q(heat)= 800 j
M(mass) = 30 g
C(specific heat capacity) =?
ΔT( change in temperature) = 40°c - 20°c = 20°c
make C the subject of the formula by diving both side of the formula by MΔT
C is therefore = Q/MΔT
800j / 30 g x 20°c = 1.333 j/g/°c

<h3>
Answer:</h3>
7.838 seconds
<h3>
Explanation:</h3>
- Assuming the sound of sound in seawater is 1531 m/s we can calculate the time taken by the signal to leave the ship and back.
- The depth to the bottom is 6000 meters
- The sound signal will cover the distance twice, to and fro the bottom to the ship.
- Time is calculated by dividing the distance by the velocity or speed.
In this case;
Time = (2× distance) ÷ velocity
= (2×6000) m ÷ 1531 m/s
= 12000 m ÷ 1531 m/s
= 7.838 s
Therefore, it will take 7.838 s for the sound signal to leave the ship and bounce back off and return to the ship.
