Answer:
Explanation:
The given chemical formula is;
4H₂O H₈O₄
H₂O signifies 2 atoms of hydrogen bonding with 1 atom of oxygen
H₈O₄ signifies 8 atoms of hydrogen bonding with 4 atoms of oxygen
The 4 coefficient before H₂O signifies the number of moles.
It appears H₂O is 4 moles of water
H₈O₄ is 1 mole of the compound
The number of moles of each of the compound differs.

Answer:
(i) Calculate the average rate of consumption of A in the first 15 seconds of reaction: -8.67X10^(-3) M/s
(ii) Calculate the average rate of production of C in the first 15 seconds of reaction: 0.0.17 M/s
(iii) Calculate the average rate of consumption of A in the last 15 seconds of the reaction: -3x10^(-3) M/s
(iv) Explain the difference between the rates of consumption calculated in (i) and that in (iii): At the beginning the reaction, is fast, then, when time passes, the reaction slows because there are less concentration of the reactants to produce C, so the rate is less.
Explanation:
The general formula to calculate any reaction rate is:
With this formula we can make the calculations, and we can know if r is positive or negative by knowing if we are calculating for a reactant or a product, positive for products, negative for reactants.
(i)
(ii)
In this case we need to multiply delta by 2, because 1 mole of A produces 2 moles of C:
As we know it is a product, r needs to be positive, so we change the sign of the result and we have: 0.017 M/s
(iii)
(iv)
Is already answered in the upper part.
The larger the kinetic energy of the vehicle, the larger the amount of energy will be needed to stop the vehicle, meaning that faster vehicles have a larger stopping distance
Conversion factors is a ratio expressed as fraction that equal 1.
Conversion factor is a number used to change one set of units to another by multiplying or dividing.
I don’t really get your question tho so that’s wht I’m guessing
